A is correct: A brand is the identity and reputation a company creates for its products—it's the name, logo, and promise behind what they sell (like Nike or Coca-Cola).

B is wrong: This describes the opposite. A generic or unmarked item has *no* brand—it's unbranded. Brand is about distinctive identity, not lack of it.

A is correct: "Broadcast" means to *send out* a signal or program to many people at once through radio, TV, or other media. The word comes from "broad" (wide/many) + "cast" (throw/send).

B is wrong: This describes *receiving* a broadcast, which is the opposite action. The person or device receiving is not doing the broadcasting—they're on the listening/watching end.

Correct (A): A broker acts as a middleman between buyers and sellers, earning a commission or fee for arranging transactions. They don't own the goods themselves—they facilitate deals for others.

Why B is wrong: That describes a manufacturer or direct seller, not a broker. These people produce and sell their own goods, whereas brokers handle transactions for other people's assets.

A. A financial plan. ✓
A budget is a detailed plan that outlines expected income and planned spending over a specific period. It helps you track money and make intentional financial decisions.

B. An extravagant expenditure. ✗
This is backwards—a budget is actually meant to *prevent* wasteful spending by limiting expenses. "Extravagant" means excessive or luxurious, which is the opposite of what budgeting encourages.

A. An office or agency ✓

A bureau is an official organization or department that handles specific government or business functions—like the "Federal Bureau of Investigation" (FBI) or a "travel bureau."

B. A public outdoor space ✗

This describes a park or plaza, not a bureau. While a bureau might *be located in* a public space, that's not what the word means.

Correct Answer: A. An occupation or trade.

Business refers to organized work or commercial activity done to earn money and provide goods or services to others. It's a professional pursuit, not a casual pastime.

Why B is wrong:
A hobby or leisure activity is done for personal enjoyment in free time, not as a primary income source. Business is structured, intentional work with a profit motive—the opposite of leisure.

Why A is correct:
CEO stands for "Chief Executive Officer"—the top leader of a company who makes major decisions and is responsible for overall performance.

Why B is wrong:
A mid-level manager describes a supervisor or department head, not the CEO. The CEO is above all other managers in the company hierarchy.

Why A is correct:
"Cable" refers to something thick and durable—like the heavy steel cables on a suspension bridge or the thick cord that carries electricity to your home. It's designed to support weight and withstand tension.

Why B is wrong:
A light, flexible string describes something like twine or yarn—the opposite of a cable. Cables are specifically characterized by being thick and strong, not delicate or light.

A is correct. "Calculate" means to find an answer using math—whether it's addition, algebra, or other mathematical methods. It requires actual computation based on known values.

B is wrong. Guessing without basis is the opposite of calculating. Calculating is precise and based on logic/math, while guessing is random.

A. The process of using mathematics ✓

This is correct because "calculation" literally means working through numbers and math operations to find an answer. It's precise and deliberate.

B. An act of making a wild guess ✗

This is wrong because a guess is the opposite of calculation—it's random and unthinking. Calculation requires careful, methodical work with numbers.

Correct Answer: A system of organizing days

A calendar is specifically designed to organize and track time by dividing it into days, weeks, months, and years. This helps people plan, schedule events, and keep track of dates.

Why B is wrong:

A device that measures physical properties describes something like a thermometer (temperature), ruler (length), or scale (weight). A calendar doesn't measure physical properties—it organizes information about time instead.

# Explanation

A. To communicate by phone. ✓
This is the primary definition of "call" in everyday English. When you "call someone," you're reaching out to them by telephone to have a conversation.

B. To ignore someone. ✗
This is the opposite of what "call" means. Ignoring someone means avoiding contact with them, not communicating with them. This contradicts the actual definition.

Correct Answer: A

A camera is specifically designed to capture images and videos by recording light through a lens onto a sensor or film. This is its primary and defining function.

Why B is wrong:
A thermometer (not a camera) measures temperature. While cameras do have electronic sensors, those sensors detect light, not heat, so measuring temperature is not what cameras do.

A is correct: A campaign requires planning and coordination—like a political campaign, marketing campaign, or military campaign. All involve deliberate steps working toward a specific objective.

B is wrong: This contradicts what a campaign actually is. Campaigns are the *opposite* of spontaneous—they're structured and intentional, not random or unplanned.

Correct answer: A. The grounds and buildings of a university.

"Campus" refers to the physical property where a university or college is located—the land, buildings, and facilities students and staff use. This is the standard definition you'll find in any dictionary.

Why B is wrong:
Option B describes the opposite of a campus. An isolated area *away* from educational institutions would be the last place you'd find a campus. A campus is specifically designed to be a hub of academic activity, not a remote location.

A. To call off ✓

Cancel means to stop something that was planned or scheduled—like canceling a meeting or a flight reservation. You're ending it and it won't happen.

B. To confirm ✗

This is the opposite of cancel. Confirming means to verify or approve that something *will* happen, whereas canceling means it *won't* happen.

Correct Answer: A person who applies for a job.

A candidate is someone actively seeking a position—they've submitted an application or expressed interest. This is the standard meaning in hiring and elections.

Why B is wrong: Rejecting a job is the opposite of what a candidate does. A candidate pursues opportunities; they don't turn them down before even applying.

Why A is correct:
Canvas is a heavy, tightly-woven fabric specifically designed to be a surface for painting. Artists stretch it over frames and apply paint to it.

Why B is wrong:
Canvas is actually quite sturdy and thick—the opposite of soft. Soft, delicate fabrics like silk or cotton are used for clothing, not canvas.

Correct Answer: A. The power or ability to do something.

"Capability" refers to having the skill, strength, or means to accomplish a task or action. It's about what someone or something is able to do.

Why B is wrong:
Option B describes the opposite—inactivity means doing nothing, while capability is about having the potential to act or perform. They're completely contradictory concepts.

A is correct: "Capable" means having the skill, knowledge, or power to do something. If someone is capable, they're competent and able to handle a task.

B is wrong: This describes someone who is *apathetic* or *unmotivated*—the opposite of capable. Being capable is about having ability, not about lacking interest.

A is correct. Capacity means the maximum amount or volume that something can hold or contain—like a bucket's capacity or a stadium's seating capacity.

B is wrong. This describes a *lack* of capacity or inability, which is the opposite meaning. The word "incapacity" means inability to function, not capacity itself.

A is correct. A captain is the person in charge who gives direction and makes decisions for a group—like a ship captain commanding a vessel or a sports team captain leading players.

B is wrong. That describes a regular member or subordinate who takes orders *from* the captain, not the captain themselves. The captain is the opposite—they're the one giving the orders.

A is correct. "Capture" means to take control of someone or something, usually against their will or by using force. Think of capturing a criminal or capturing a city in war.

B is wrong. This describes the opposite action—releasing or freeing something. That's closer to words like "liberate" or "release," not "capture."

A is correct: A "card" is a common everyday object made from sturdy paper material—like a greeting card, playing card, or ID card.

B is incorrect: While digital platforms exist for software, that's not what "card" means. You might be thinking of an "app store" or similar service, but those aren't called cards.

Why A is correct:
A career is a long-term professional journey, not just any job. It involves building skills, experience, and progression over years—like becoming a teacher, engineer, or nurse.

Why B is wrong:
That describes a temporary job or gig work (like seasonal retail or freelance tasks). These are short-term and don't constitute a "career" because they lack the ongoing development and commitment that defines one.

Why A is correct:
A carrier is literally something that transports or holds something else—like a mail carrier delivers letters, or a grocery bag is a carrier for items. It's the active agent doing the carrying.

Why B is wrong:
This describes a barrier or obstacle, not a carrier. A carrier *enables* movement by transporting things, rather than restricting it. Elements that restrict movement would be impediments or obstacles, not carriers.

A is correct. "Carve" means to cut or shape something by removing material—like carving a turkey, sculpting wood, or etching designs into stone.

B is wrong. Smoothing or polishing makes something sleeker, but carving is the opposite—it removes material to *create* a shape rather than refine an existing surface.

A is correct. A "case" refers to a specific example or occurrence of something—like "a case of the flu" means one instance of someone having the flu, or "a legal case" is one particular situation being examined in court.

B is wrong. A case is not permanent; it's typically temporary or limited to a particular situation. For example, once someone recovers from the flu, that case is over. If something were permanent, we wouldn't call it a "case."

A is correct: A catalog is an organized, systematic list—like a library catalog listing books, or a store catalog showing products. It's designed for easy reference and browsing.

B is wrong: A catalog is the *opposite* of chaotic. It's carefully organized and arranged, not random or messy. "Unrelated items" also misses the point—catalogs typically group similar things together.

A is correct: A cell is fundamentally a small, enclosed space—whether it's a prison cell, a monk's cell, or a biological cell in your body. The word comes from Latin meaning "to hide or conceal," reflecting the idea of something small and contained.

B is wrong: This is the opposite meaning. An extensive open space describes something large and unrestricted, which contradicts what a cell is.

A is correct: A chain is defined by its connected structure—multiple links joined together to form one unit. This is its essential characteristic.

B is wrong: A single, unlinked piece describes an individual object in isolation, not a chain. A chain requires multiple elements connected together.

A is correct. A chairman is the highest-ranking person who leads meetings, makes decisions, and directs an organization or board.

B is wrong. The person who takes notes is called a secretary or note-taker, not a chairman. They have a supporting role, not a leadership role.

Why A is correct:
A "challenge" is something that requires effort and skill to overcome—it's inherently difficult or demanding. That's the core meaning of the word.

Why B is wrong:
This contradicts the actual definition. Easy tasks aren't challenges; they're routine. A challenge specifically means something that tests your abilities and pushes you beyond what's easy.

A is correct. A chapter is a distinct section within a book that divides the story or content into manageable parts, usually with its own heading or number.

B is wrong. While a collection of poems is sometimes organized into sections, that's not what "chapter" means. Poems are typically organized into collections or volumes, not chapters.

Why A is correct:
A chart is specifically a visual tool—like a graph, bar chart, or pie chart—designed to display data in a way that's easy to understand at a glance.

Why B is wrong:
A written explanation of an event describes a narrative or account, which is not what "chart" means. That would be more like a story or report, not a chart.

A. A document defining rights ✓

A charter is an official document that establishes rules, rights, and powers—like a constitution or formal agreement. Think of it as a legal blueprint that says "here's what you're allowed to do and what your responsibilities are."

B. A casual agreement or informal arrangement ✗

This is backwards. A charter is the *opposite* of casual—it's formal and official. Informal agreements don't need charters; they need actual legal documents.

A. A professional cook ✓

A chef is someone trained and employed to prepare food professionally, typically in restaurants or other food service settings. This is the standard definition of the word.

B. A person who dislikes food and cooking ✗

This is the opposite of what a chef is. Chefs are passionate about food and cooking—that's why they chose the profession. This option contradicts the actual meaning of the word.

A is correct: A chemical is any substance involved in a reaction—either something you start with or something you create. This includes everything from water to medicines to cleaning products.

B is wrong: While some chemicals are natural elements, not all are. Many chemicals are human-made (like plastics or synthetic drugs), and many natural elements only become "chemicals" when used in reactions or processes, not just in their raw form.

A is correct. Chemistry is the study of matter—what substances are made of and how they react with each other. This includes atoms, molecules, reactions, and energy changes.

B is wrong. That describes astronomy or astrophysics, which focuses on stars, planets, and space—not the behavior of chemical substances.

A. A leader or ruler. ✓
"Chief" means someone in charge—the top person with authority over others. Think of a "fire chief" or "chief executive officer."

B. A minor follower without authority. ✗
This is the opposite of what "chief" means. A follower has no power, while a chief has the most power in their group.

A is correct: A circuit is a closed loop that allows electricity to flow from a power source, through components, and back. Think of it like a circular route—the current needs a complete path to travel.

B is wrong: An open space without connections is the *opposite* of a circuit. Without connections, electricity can't flow, so there's no circuit at all.

A. To mention as a source. ✓

When you cite something, you're giving credit by naming where information came from—like citing a book, website, or person in an essay. This is the correct meaning used in academic and professional writing.

B. To hide or keep secret. ✗

This is the opposite of what "cite" means. Citing actually makes sources *visible* and public, not hidden.

Why A is correct:
"Class" refers to a group of students learning together in the same setting, typically with one teacher. This is the standard definition used in education.

Why B is wrong:
That describes "distance learning" or "online instruction"—not a class. A class requires students to be grouped together (whether in person or virtually as a cohesive group), not individual isolated instruction.

Correct Answer: A place where teaching occurs.

A classroom is specifically designed as a learning space where teachers instruct students and educational activities happen. This is the primary purpose and defining feature of a classroom.

Why B is wrong:

While classrooms may contain some stored materials (like books or supplies), storage is not what makes a space a "classroom." A storage room or supply closet isn't called a classroom, even if it holds materials. The essential function is teaching and learning, not storage.

Correct Answer (A):
A clerk handles paperwork, filing, scheduling, and other office support work. This is the standard definition of the role across most organizations.

Why B is wrong:
A person who oversees construction is called a foreman or construction manager, not a clerk. Construction supervision involves managing workers and projects on-site, which is very different from clerical work.

A. A short, sharp sound. ✓
"Click" describes a brief, distinct sound—like a pen clicking or a door latch closing. It happens quickly and then stops.

B. A long, continuous noise. ✗
This describes a sound that keeps going (like a hum or buzz), not a click. A click is over in an instant.

Why A is correct:
A client is the person or organization who *receives* professional services and pays for them. Think of it as the customer in a professional relationship.

Why B is wrong:
B describes the opposite relationship. The service provider (lawyer, accountant, doctor) is the professional offering help, not the client. The client is the one *hiring* that professional.

Correct answer: A

A "clip" is a small section extracted or cut out from something larger—like a video clip from a movie, or a news clip from a broadcast. It's a shortened piece meant to stand alone.

Why B is wrong:

Option B describes the opposite of a clip. An entire long piece kept intact would be the *full* version, not a clip. A clip is always *part* of something bigger, not the whole thing.

A is correct. A clue is specifically information that *helps* you figure something out—like a hint in a game or evidence in a detective story.

B is wrong. While an obstacle might create confusion, it blocks progress rather than helping to solve something. That's the opposite of what a clue does.

A is correct: A cluster means items that are alike and bundled closely together—like a cluster of grapes or a star cluster in space.

B is wrong: This describes the opposite of a cluster. If things are "widely spread" and "diverse," they're scattered and different, not clustered. A cluster requires proximity and similarity.
