# Explanation

A is correct: An antioxidant *prevents* (menghambat) oxidation—the chemical process that causes food to spoil, rust, or go bad. Antioxidants protect stored food by stopping this damage.

B is wrong: This describes the opposite effect. It says antioxidants *promote* (mempromosikan) oxidation and *cause* food damage, which is backwards. That would make them harmful, not helpful.

Key point: The prefix "anti-" means "against," so antioxidant = against oxidation = protection.

Why A is correct:
Asthma is a breathing disorder where the airways in your lungs suddenly tighten (spasm), making it hard to breathe. This definition accurately describes what asthma is—a respiratory condition with airway spasms causing breathing difficulty.

Why B is wrong:
This describes the *opposite* of asthma. Asthma makes breathing *harder*, not easier. Option B contradicts the actual nature of the disease.

Correct Answer (A):
"Biochemistry" combines "bio" (life) + "chemistry" (chemical processes). It's the study of chemical reactions that happen inside living things—like how your body breaks down food or how DNA works. This definition is accurate.

Why B is wrong:
Option B says biochemistry studies *physical* processes that are *not* related to living organisms. This is backwards on both counts:
- Biochemistry focuses on *chemical* processes, not just physical ones
- It specifically deals with processes *in and related to* living things, not processes unrelated to life

# Cystic Fibrosis Explanation

Why A is correct:
Cystic fibrosis is an inherited disorder affecting exocrine glands (sweat, mucus, digestive glands). The key feature is abnormally thick mucus that clogs airways and organs, causing breathing and digestion problems.

Why B is wrong:
CF produces abnormally thick mucus, not thin mucus. Thin mucus wouldn't cause the characteristic lung blockages and infections that define the disease.

Correct Answer (A): This is the accurate definition of dyslexia. It's a learning disorder that makes reading and interpreting letters, words, and symbols difficult—the "dys-" prefix means difficulty or disorder.

Why B is wrong: This describes the *opposite* of dyslexia. It says reading and interpreting symbols is *easy*, when dyslexia actually makes these tasks *hard*. This definition describes typical, fluent reading ability, not a learning disorder.

Correct Answer (A): The endocrine system is literally defined as the body system made up of endocrine glands (like the pancreas, thyroid, and adrenal glands) and the hormones they produce. These hormones control important functions like growth, metabolism, and reproduction.

Why B is wrong: Option B says the endocrine system has *no* endocrine glands and hormones—this is the opposite of the actual definition. That would describe a system that doesn't exist.

Correct Answer (A): "Gastroenteritis" literally means inflammation ("itis") of the stomach ("gastro") and intestines ("enteritis"). This condition is commonly caused by bacterial toxins or viral infections—exactly what option A describes. This is the accurate medical definition.

Why B is wrong: Option B describes a *healthy* state (no inflammation), which is the opposite of gastroenteritis. The condition involves inflammation, not freedom from it.

# Hypoxia Explanation

Correct Answer (A): Kekurangan dalam jumlah oksigen yang mencapai jaringan
- "Hypo-" means "below/under" and "-oxia" refers to oxygen, so hypoxia literally means "below normal oxygen"
- This is when tissues don't get enough oxygen to function properly, which can happen due to lung disease, anemia, or circulation problems

Why B is wrong:
- That describes "hyperoxia" (excess oxygen), not hypoxia
- "Hyper-" means "above/over," which is the opposite prefix
- Too much oxygen can also be harmful, but that's not what hypoxia means

Why A is correct:
Iodine deficiency means your body doesn't have *enough* iodine because you're not eating enough foods containing it. The key word is "ketidakseimbangan" (imbalance/deficiency) and "tidak cukup" (insufficient).

Why B is wrong:
This describes the *opposite* situation—having enough iodine and good nutrition balance. It says "keseimbangan" (balance), which is the positive state you want, not the problem of deficiency.

Why A is correct:
"Jogger's Knee" is an actual injury condition common in runners where repetitive stress on a small area of the knee causes pain. This matches option A perfectly—it defines it as a common injury among runners caused by stress leading to pain.

Why B is wrong:
Option B describes a knee with *no* stress or pain, which is the opposite of what "Jogger's Knee" is. This would describe a healthy knee, not an injury condition.

Correct Answer (A):
"Kinesiology" comes from Greek words meaning "movement" (kinesis) and "study" (logos). It's the science of how bodies move and function mechanically during activity.

Why B is wrong:
Kinesiology focuses on *movement and activity*, not rest and inactivity. While rest is important for recovery, it's not what kinesiology studies. The word itself literally describes the opposite of inactivity.

Why A is correct:
Bronchial asthma is literally inflammation and narrowing of the bronchial tubes, causing them to swell and produce excess mucus—this directly restricts airflow and makes breathing difficult. This matches the definition exactly.

Why B is wrong:
This describes the opposite of asthma. Option B says the tubes expand and clear with no extra mucus, which would *improve* breathing. Asthma does the opposite—it constricts the airways and increases mucus production.

# Explanation

Correct Answer (A): "Hyper-" means "above/excessive" and "-thermia" means "heat," so hyperthermia literally means abnormally high body temperature. This is the medical definition—dangerously elevated core body temperature from extreme heat exposure or other causes.

Why B is wrong: Option B describes hypothermia (low body temperature from cold), which is the opposite condition. The prefix "hypo-" means "below/deficient," not "hyper."

Correct Answer (A):
Lactose intolerance means the body cannot fully digest lactose (the sugar in milk and dairy products). People with this condition lack enough lactase enzyme to break down lactose, causing digestive discomfort.

Why B is wrong:
Option B says the body can digest lactose fully, which is the opposite of what lactose intolerance means. That would describe someone *without* the condition.

# Explanation

A is correct: Metabolic Syndrome is a *cluster of conditions* (high blood pressure, high blood sugar, excess body fat, abnormal cholesterol) that work *together to increase* your risk of serious diseases like heart disease, stroke, and type 2 diabetes. It's a dangerous combination that makes these health problems more likely.

B is wrong: It says these conditions *decrease* risk, which is backwards. Metabolic Syndrome actually *raises* your risk, not lowers it. Having these conditions together makes you more vulnerable to disease, not less.

Correct answer (A): This is right because orthodontics literally means "straight teeth" (ortho = straight, dontics = teeth). It's the dental specialty focused on preventing and correcting misaligned teeth and bite problems—like using braces or aligners.

Why B is wrong: While orthodontists do address the *causes* of misalignment, that's not the main definition of the field. Orthodontics is primarily about the treatment and prevention of tooth irregularities, not investigating their underlying causes (that would be more aligned with other dental specialties).

Why A is correct:
Addiction is compulsive engagement with rewarding stimuli *despite* harmful consequences—you continue even when you know it's hurting you. This captures the core definition: loss of control combined with continued use despite negative outcomes.

Why B is wrong:
This describes the opposite of addiction. It says people *avoid* rewarding stimuli, which is not addiction. Also, "positive consequences" doesn't fit—addiction involves *negative* consequences that the person ignores or can't stop despite.

# Explanation

A is correct: An embolus is exactly what this describes—any foreign material (blood clot, air bubble, fat deposit, etc.) that travels *through* the bloodstream and lodges in a vessel, blocking blood flow. This obstruction is called an embolism.

B is wrong: This describes something *outside* the bloodstream that doesn't cause an embolism. An embolus must be *inside* the circulation and *must* cause a blockage—that's the whole point of the term.

# Why A is correct:

A defibrillator delivers (memberikan) a high-energy electric shock to the heart through the chest wall to restore normal heart rhythm during a heart attack. This is exactly what the device does—it actively sends electricity to fix an irregular heartbeat.

# Why B is wrong:

B says the device prevents (mencegah) electric shocks, which is backwards. A defibrillator doesn't block or prevent electricity; it *provides* electricity as a life-saving treatment. Prevention would be the opposite of what a defibrillator actually does.

Correct Answer (A): An electrocardiograph *measures* and records the heart's electrical activity—the prefix "electro-" means electrical, and "cardio-" means heart. This is exactly what the machine does: it detects and graphs these signals.

Why B is wrong: It says the machine *stops* ("menghentikan") the heart's electrical activity, which is incorrect and dangerous. An ECG is diagnostic only—it observes without interfering with heart function.

Why A is correct:
A ligament is fibrous connective tissue that connects bones together and holds joints stable—it must be flexible to allow movement while remaining strong. This definition matches the actual anatomical function of ligaments.

Why B is wrong:
- Describes tissue as "rigid/stiff" and "inflexible"—ligaments are actually flexible
- Says it "separates" and "pushes apart" bones—ligaments do the opposite; they connect and hold bones together
- This describes a barrier, not a joint-supporting structure

# Explanation

Correct Answer (A): This accurately defines herniated disc—the disc material protrudes or bulges outward from its normal position between vertebrae, often due to injury or aging. "Menonjol" (protrude/bulge) is the key term.

Why B is wrong:
- Uses "menyusut atau menguncur" (shrink or slip), which describes disc degeneration or slippage, not herniation
- A herniated disc doesn't shrink; material pushes *out* of the disc, not away from it
- This describes a different spinal condition

Correct Answer (A): A ligament tear is indeed a painful condition caused by stretching or tearing of ligaments in the body. Ligaments are connective tissues that hold bones together, so when they tear, they cause pain and loss of stability in joints.

Why B is wrong:
- B describes ligaments becoming hardened or compacted, which is not what a tear is
- Tears are acute injuries, not a hardening process
- A tear would cause pain, not be painless as option B suggests

# Why A is correct:

Carpal Tunnel Syndrome occurs when the median nerve gets compressed (squeezed) in the wrist, causing pain, numbness, and tingling. This compression is what defines the condition.

# Why B is wrong:

• Says the nerve is "enlarged/expanded" rather than compressed—this is the opposite of what happens
• Says it's "painless"—but CTS actually causes significant pain and discomfort, which is a main symptom
• Completely mischaracterizes the condition

Correct Answer (A): Strep throat is a bacterial infection caused by *Streptococcus pyogenes* bacteria. It causes pain and inflammation (swelling and redness) in the throat—these are the defining symptoms.

Why B is wrong: Option B says strep throat causes relief and a cold sensation, which is completely backwards. Strep throat causes discomfort and pain, not relief. This describes the opposite of what actually happens.

# Explanation

Option A is correct because gallstones are literally hardened deposits (usually made of cholesterol or bilirubin) that form in the gallbladder and can cause pain, inflammation, and serious complications like blockages or pancreatitis.

Option B is wrong because it describes deposits as soft and liquid, which is the opposite of what gallstones actually are—they're solid, stone-like formations. Also, gallstones cause problems, not wellness or positive effects.

Correct Answer (A): A peptic ulcer is an *open sore* (luka terbuka) that forms in the inner lining (lapisan dalam) of the stomach or upper small intestine. The word "peptic" refers to the digestive acids involved, and "ulcer" means an open wound—so this definition is anatomically accurate.

Why B is wrong:
- Says the area is "closed and healed" (tertutup dan sembuh)—but an ulcer is by definition an *open* sore, not a healed one
- Mentions the "lower small intestine" (usus kecil bagian bawah)—peptic ulcers occur in the stomach or *upper* small intestine (duodenum), not the lower part

Correct Answer (A): Peradangan paru-paru yang disebabkan oleh infeksi.
- This is the accurate medical definition: pneumonia is inflammation of the lungs caused by infection (bacterial, viral, or fungal).

Why B is wrong:
- It describes lung *healing* due to decreased infection, which is the opposite of what pneumonia is. Pneumonia is the disease itself (inflammation from active infection), not recovery from it.

Why A is correct:
"Tonsillitis" literally means inflammation (-itis) of the tonsils (tonsil-). It's an infection causing swelling, redness, and soreness of the throat tissues.

Why B is wrong:
This describes the opposite of tonsillitis. It talks about shrinkage or reduction of tonsils from good health, when tonsillitis actually causes swelling and is a medical problem, not a healthy condition.

Option A is correct because acne is specifically a skin condition characterized by red pimples/spots, usually appearing on the face and other areas. This matches the medical definition.

Option B is wrong because it describes the opposite—clean, smooth skin. Acne is a problematic skin condition, not a healthy one.

Why A is correct:
Melanoma literally means "black tumor" (melano = pigment, oma = tumor). It specifically refers to cancer of melanocytes (pigment-producing cells), which can spread to other parts of the body if not treated early.

Why B is wrong:
Melanoma is a serious cancer, not a skin rejuvenation treatment. While melanocytes are correctly identified, the definition incorrectly describes regeneration and health improvement instead of malignant mutation—the opposite of what melanoma actually is.

Why A is correct:
Astigmatism is a refractive error where the cornea or lens has an irregular curve (not perfectly spherical). This causes light rays to focus at different points rather than one single point, creating blurred or distorted vision. Option A accurately describes this.

Why B is wrong:
Option B describes perfect vision (emmetropia), where light focuses correctly on the retina. This is the opposite of astigmatism—it's what happens when the eye *doesn't* have this defect.

A is correct because basal cell carcinoma is specifically a *cancer* (carcinoma) that originates in the basal cells of the skin's deepest layer. The term "carcinoma" is the medical term for cancer.

B is wrong because it says "kesehatan kulit" (skin health condition) instead of cancer. While basal cell carcinoma does affect skin, it's a malignant disease, not just a general health condition. The word "carcinoma" in the name specifically indicates cancer, not a benign skin issue.

Correct Answer (A): A cataract is when the eye's lens gradually becomes cloudy, causing blurry vision. This is the actual medical definition—the cloudiness blocks light from passing through clearly.

Why B is wrong: Option B describes the opposite situation—a clear lens and perfect vision. This is normal, healthy eyesight, not a cataract. A cataract is specifically a *problem* with the lens, not the absence of one.

Correct answer (A): Diphtheria is a serious bacterial infection that attacks the mucous membranes of the nose and throat, causing a thick, grayish coating and potentially life-threatening complications like difficulty breathing and heart damage.

Why B is wrong: This describes a *beneficial* bacterial effect, but diphtheria is the opposite—it's a dangerous disease caused by toxins from *Corynebacterium diphtheriae* bacteria. There's nothing beneficial about it; it's a serious illness that requires immediate treatment and vaccination to prevent.

Correct Answer (A):
Ehrlichiosis is a disease caused by bacteria transmitted through tick bites. This accurately describes the condition: it's an infection from *Ehrlichia* bacteria that spreads when an infected tick bites a person.

Why B is wrong:
Option B incorrectly claims the bacteria are "beneficial" and "promote health." In reality, ehrlichiosis causes illness with symptoms like fever, headache, and muscle aches—it's harmful, not helpful.

Correct Answer (A): Fibrosis means thickening and hardening of connective tissue, usually from injury. This is the medical definition—when tissue is damaged, scar tissue (made of fibrous material) builds up and becomes thick and stiff.

Why B is wrong:
- It says "thinning" instead of thickening—the opposite of what happens
- It says tissue heals due to "health," which doesn't make sense; fibrosis is a *problem* caused by injury or disease, not a healthy process
- Fibrosis is abnormal scarring that limits movement and function, not normal healing

Correct Answer: A. Peradangan gusi (Gum inflammation)

Gingivitis comes from "gingiva" (gums) + "-itis" (inflammation). The suffix "-itis" always means inflammation of something, so gingivitis literally means inflamed gums—a disease where gums become red, swollen, and may bleed.

Why B is wrong:
"Penyembuhan" means healing or recovery. Gingivitis is the *disease* (inflammation), not the healing process. The opposite of gingivitis would be healthy gums, not "penyembuhan."

Correct Answer (A):
The prefix "hypo-" means low or below normal, so "hypoalbuminemia" literally means low albumin in the blood. This is a real medical condition that occurs in liver disease, malnutrition, and kidney problems.

Why B is wrong:
Option B describes high albumin levels, which would be "hyperalbuminemia" (using the prefix "hyper-" meaning high). This is the opposite of what "hypo-" means.

Correct Answer (A): This accurately defines Interstitial Cystitis as a chronic condition causing bladder pressure, bladder pain, and sometimes pelvic pain—which matches the actual medical definition of this disorder.

Why B is wrong: It describes bladder *comfort* and *health* instead of pain and pressure. This is the opposite of what IC actually causes—it's a painful condition, not a comfortable or healthy one.

Correct Answer (A): The jugular vein carries blood *back to* the heart from the head. Veins always return blood toward the heart, which is their defining function.

Why B is wrong: This describes an *artery*, not a vein. Arteries pump blood *away from* the heart to body parts. The jugular vein does the opposite—it collects used blood from the head and returns it to the heart.

Correct Answer (A): Platelets are tiny blood cells that stick together to form clots and stop bleeding when you get a cut or injury. This is their main job in your body.

Why B is wrong: That description is for the kidneys, not platelets. Kidneys are large organs that filter waste from your blood, which is completely different from what platelets do.

Correct Answer (A): This accurately describes the gallbladder—a small organ that stores bile (empedu) until it's needed to digest fats in the small intestine (usus kecil).

Why B is wrong: That describes the heart (jantung), not the gallbladder. The heart is a large organ that pumps blood throughout the body, which is a completely different function.

Correct Answer (A): Vena yang telah menjadi membesar dan bengkok.
- "Varicose" means abnormally enlarged and twisted, which is exactly what happens to veins in this condition—they become swollen and contorted, usually in the legs.

Why B is wrong:
- Varicose veins don't become smaller; they become *larger*. They also don't straighten—they become twisted and irregular in shape. This describes the opposite of what actually happens.

Correct Answer (A): An antigen is any substance that triggers the immune system to respond, mainly by producing antibodies. When your body detects a foreign substance (like a virus or bacteria), it identifies it as an antigen and creates antibodies to fight it.

Why B is wrong: This describes an immunosuppressant, which does the opposite—it *weakens* the immune response rather than triggers it. Antigens activate immunity, not suppress it.

A is correct: Lymph nodes are small glands that filter lymph (fluid circulating through the lymphatic system). They trap bacteria, viruses, and other harmful particles, helping your immune system fight infection.

B is wrong: This describes the bone marrow, which produces blood cells. Lymph nodes don't produce blood cells—they filter lymph fluid.

Why A is correct:
Surgical sutures are literally stitches that hold tissues together after they're cut. They join skin, organs, blood vessels, and other tissues after injury, surgery, or incisions—this is their core function.

Why B is wrong:
B describes instruments that *separate* tissues during surgery (like scalpels or scissors). Sutures do the opposite—they *join* tissues back together after separation. This is a completely different purpose.

Correct answer (A): "Benign" means harmless or not dangerous. In medical terms, a benign tumor is non-cancerous and won't spread or threaten life—it's the safer type of tumor.

Why B is wrong: This describes a *malignant* tumor, which is the opposite of benign. Malignant tumors are dangerous, cancerous, and can spread. The word "benign" literally means the opposite of what option B states.

Correct Answer (A): "Malignant" means dangerous and spreading—it describes cancerous tumors that grow aggressively and can spread to other parts of the body. This is the medical definition used by doctors.

Why B is wrong: Option B describes the opposite meaning. "Benign" (not "malignant") means harmless and non-cancerous. Malignant tumors are the dangerous ones, not the safe ones.

A is correct: Laryngitis literally means inflammation (-itis) of the larynx (voice box). When inflamed, the larynx produces the symptoms listed: hoarseness, voice loss, rough breathing, and painful cough.

B is wrong: This describes a *healthy* larynx, which is the opposite of laryngitis. Laryngitis is a medical condition, not a healthy state.
