Prepositions

"Interested in" is the correct collocation — this is the standard phrase we use in English.

• A (in) ✓ Correct. "Be interested in [noun/gerund]" is the fixed expression we use: "interested in learning," "interested in sports," etc.
• B (for) ✗ Wrong. "Interested for" isn't idiomatic English.
• C (from) ✗ Wrong. "Interested from" doesn't make sense here.
• D (to) ✗ Wrong. We don't say "interested to learning." ("Interested to hear" exists, but only with certain verbs like hear, see, learn as main verbs—not gerunds.)

Correct answer: WITH

When describing an emotion directed at a person, we use "angry with" (or "angry at"). This is the standard English idiom.

Why the others are wrong:
- In: Not used with emotions toward people ("angry in" isn't correct)
- From: Used for sources or origins, not emotions ("angry from" would imply anger originated from the friend, which is awkward)
- Of: Used for possession or type, not emotions toward people ("angry of" is not standard English)

Why A (at) is correct:
Use "at" for specific locations or points. You arrive "at" a particular place like an airport, station, or building.

Why the others are wrong:
- B (in): Use "in" for enclosed spaces or cities/countries, not for arriving at specific buildings ("in Paris" yes, "in the airport" no)
- C (on): "On" is for surfaces or transport ("on the plane," "on time"), not for arriving at a destination
- D (from): "From" shows where you came from, not where you're arriving ("from the airport," not "to the airport")

Correct answer: A (to)
- "Going to" is the standard phrase showing direction or destination—you're moving toward the office.

Why the others are wrong:
- B (at) - "At" shows location/position, not movement ("I'm at the office" = already there)
- C (from) - "From" shows origin/starting point, the opposite direction ("coming from the office")
- D (in) - "In" shows being inside something, not the act of going there ("in the office" = already inside)

A. on ✓
"On the phone" is the standard English phrase for using a telephone to communicate. It's the accepted idiom.

B. at ✗
"At the phone" would mean he's physically near the phone, not using it to talk.

C. from ✗
"From the phone" doesn't make grammatical sense in this context.

D. in ✗
"In the phone" is incorrect—we don't use "in" with this phrase.

Correct answer: A (about)
"Thinking about" is the standard phrasal verb used when you're considering or reflecting on someone. It means your mind is focused on that person.

Why the others are wrong:
- B (in): "Thinking in" isn't a common phrasal verb; it would suggest thinking *inside* something, which doesn't fit here.
- C (from): "Thinking from" doesn't make sense; it would imply your thoughts originate *from* your friend, which isn't the intended meaning.
- D (of): While "thinking of" can sometimes work (especially in British English), "thinking about" is more natural and more commonly used in American English.

A. for ✓
"For" is correct because we use it to show the occasion or reason for receiving something. "A gift for her birthday" means the gift was given on/because of her birthday.

Why the others don't work:
- B. in – "In" refers to time periods (in March, in 2020), not specific occasions like birthdays
- C. from – "From" shows who gave the gift, not when: "a gift from her friend"
- D. of – "Of" shows possession or what something is made of, not occasion: "a gift of jewelry" (though less common)

A. from ✓
"Come from" is a fixed phrase meaning "originate in" or "be born/raised in." It's the standard way to describe where someone is originally from.

B. in ✗
"Come in" means to enter, not to originate. You'd say "He lives in a small town," not "comes in."

C. to ✗
"Come to" means to arrive at a destination, not where someone is from. Example: "He comes to the office daily."

D. of ✗
"Come of" isn't a standard phrase. You'd never say "comes of a town."

A. in ✓
We use "in" for places, especially larger areas like cities, countries, or regions. "I live in New York" is the standard way to say where you're located.

B. for ✗
"For" shows purpose or duration ("I work for a company" or "I stayed for two weeks"), not location.

C. from ✗
"From" shows origin or where something came out of ("I'm from France"), not where you currently live.

D. of ✗
"Of" shows possession or belonging ("the mayor of the city"), not where someone lives.

Why A is correct:
"Afraid of" is the standard English phrase. When you fear something, you use "of" after "afraid."

Why the others don't work:
- B (in): "In" doesn't pair with "afraid." You wouldn't say "afraid in spiders."
- C (from): "From" suggests spiders are the source of fear coming toward him, but "afraid of" is the proper expression.
- D (to): "Afraid to" means you're hesitant to do something (e.g., "afraid to speak"), not that you fear something itself.

Why A is correct:
"Borrow from" is the standard phrasal verb meaning to take something temporarily with the intention of returning it. The library is the source or origin of the borrowed item.

Why the others are wrong:
- B (in): "In" shows location (the book is physically in the library), but doesn't express the borrowing action
- C (to): "To" indicates direction/destination, but you borrow *from* a source, not *to* it
- D (of): "Of" shows possession or relationship, but isn't used with the verb "borrow"

A. at ✓
Use "at" for specific times of day (at 9am, at noon, at 3:30pm).

B. in ✗
"In" is for longer periods (in an hour, in the morning, in 2024), not exact clock times.

C. on ✗
"On" is for days and dates (on Monday, on June 5th), not times.

D. from ✗
"From" indicates a starting point in a range (from 9am to 5pm), not when something begins.

A. for ✓
"Wait for" is the correct phrasal verb/preposition combination. "She has been waiting for him" means she expects his arrival.

Why others are wrong:
- B. in – "Waiting in" means waiting inside a place, not waiting for a person to arrive
- C. from – "From" indicates origin or starting point, not expectation of someone's arrival
- D. of – "Of" shows possession or relationship, not the act of anticipating someone

A. for ✓
"For" is correct because it shows duration—how long something lasted. "He lived there for 10 years" means the 10-year period is complete.

B. in ✗
"In" refers to a time period when something happens, not how long it lasts. ("In 2015" or "in the summer")

C. from ✗
"From" starts a time range but needs an ending point. ("From 2010 to 2020")

D. of ✗
"Of" shows possession or relationship, not duration. It doesn't work here grammatically.

• A (on) – CORRECT. Use "on" with specific days and parts of the week: "on Monday," "on the weekend," "on Friday night."

• B (in) – Wrong. "In" is for months, years, seasons, or longer periods: "in July," "in winter."

• C (at) – Wrong. "At" is for specific times: "at 3 p.m.," "at noon."

• D (from) – Wrong. "From" shows a starting point in time or space, but doesn't fit here: "from Monday to Friday" would need another preposition after.

A. among ✓

"Among" is correct because it means "in the company of" or "surrounded by a group." She is the tallest when compared to the people in her group of classmates.

Why the others don't work:
- B. in – Would need "in the class," not "in her classmates"
- C. from – Means "originating at," which doesn't fit this comparison
- D. of – While "of" can show possession/relationship, "tallest of her classmates" is less natural in modern English than "among"

Correct answer: A (at)
- "Stay at a hotel" is the standard phrase in English. We use "at" for specific locations or destinations where people temporarily lodge.

Why the others are wrong:
- B (in): "In a hotel" means inside the building itself (e.g., "She's in a hotel room"), not the act of staying/lodging there.
- C (on): "On" is used for surfaces or positions (e.g., "on a table"), not for lodging.
- D (from): "From" indicates origin or direction, not location (e.g., "They came from a hotel").

• A. in ✓ Correct. Use "in" for a duration of time extending into the future (in 5 minutes, in two hours, in a week).

• B. at ✗ Wrong. "At" specifies an exact clock time (at 3 PM, at noon), not a duration from now.

• C. from ✗ Wrong. "From" indicates a starting point (from Monday, from 2 PM), not when something will happen in the future.

• D. to ✗ Wrong. "To" shows direction or range (Monday to Friday), not a future time point.

Why A is correct:
"In" is the right preposition for location inside a space. You sit *in* a row (you're positioned within it).

Why the others are wrong:
- B (for): "For" shows purpose or direction, not location ("I sit for the test" doesn't work here)
- C (from): "From" shows origin or starting point, not where you currently are
- D (of): "Of" shows possession or connection ("the front of the row" is different from "in the front row")

Why A is correct:
"Talk about" is the correct phrasal verb. When discussing a topic or subject, you always "talk about" it.

Why the others are wrong:
- B (in): "In September" works for timing, but "talking in September" means *when* they talk, not what they're discussing
- C (from): "Talk from" isn't a natural English phrase for this meaning
- D (of): "Talk of" is archaic/poetic; modern English uses "talk about" for discussing topics

A. from ✓
When you receive something, it comes from the sender. "She received a letter from her grandmother" means the grandmother sent it to her.

B. in ✗
"In" shows location or containment (a letter *in* a box), not the source of the letter.

C. to ✗
"To" indicates direction toward someone. This would mean the letter was going *toward* the grandmother, not that she sent it.

D. of ✗
"Of" shows possession or connection (a letter *of* apology), not who sent something.

Correct answer: A (in)
- "In the shade" is the standard phrasal combination when something is located within or surrounded by a shaded area. You park *inside* the shade.

Why the others are wrong:
- B (at) - "At the shade" suggests a specific point or destination, not a location within an area
- C (from) - "From the shade" means coming away from shade, the opposite of what we want
- D (of) - "Of the shade" doesn't create a meaningful phrase for location

Why A is correct:
"Along" means moving in a line down the street, which matches how people typically walk on streets.

Why the others are wrong:
- B (in): "In the street" suggests being surrounded by the street itself, not walking on it naturally
- C (from): "From the street" indicates a starting point or origin, not the action of walking
- D (of): "Of the street" is grammatically incorrect and doesn't make sense with "walking"

Correct answer: A (at)
- Use "at" for specific times of day (at 7pm, at 3 o'clock, at noon).

Why the others are wrong:
- B (in) – Use "in" for periods of time (in 2 hours, in the morning), not exact times.
- C (from) – "From" shows a starting point in a range (from 7pm to 9pm), not when something begins.
- D (on) – Use "on" for days/dates (on Monday, on December 25th), not times.

Correct answer: A (in)
- "Interested in" is the correct fixed phrase in English. We always say "interested in [something]."

Why the others are wrong:
- B (on): Not used with "interested" — we don't say "interested on"
- C (at): Not used with "interested" — we don't say "interested at"
- D (for): "For" doesn't work here; while you can be "eager for" something, "interested for" isn't correct

A. to ✓
"Return to" is the correct phrasal verb. It means to go back to a place. He went back *to* his home country.

Why the others are wrong:
- B. from — "Return from" means you're coming *away* from a place (e.g., "He returned from his trip"), not going back to it.
- C. for — "For" doesn't fit this meaning; it's usually about purpose or duration.
- D. in — "In" is a preposition but doesn't work with "return"; we don't say "return in."

Why A is correct:
Use "in" for enclosed spaces like rooms, buildings, or apartments. "They live in a small apartment" means they reside within that space.

Why the others are wrong:
- B (at): "At" is for specific locations or addresses, not for living inside a space ("at the corner," "at 42 Main Street")
- C (for): "For" shows duration or purpose, not location ("for two years," "for rent")
- D (on): "On" is for surfaces or top of something ("on the table," "on the floor"), not for living in a building

A. for ✓
"Wait for" is the correct phrasal verb—you wait *for* a person or thing to arrive. She is waiting for him to come out or meet her.

B. in ✗
"In" doesn't work here. You might wait *in* a place (wait in the lobby), but not wait *in* a person.

C. at ✗
"At" describes location (she's at the cinema), not the action of waiting for someone.

D. on ✗
"Wait on" means to serve someone, not to wait for them to arrive.

For is correct because we use "for" when talking about the occasion or reason for something. You received a gift because of your birthday.

• On is wrong—we use "on" for specific dates/days ("on my birthday"), not for the occasion itself.
• At is wrong—"at" refers to a point in time or location, not an occasion ("at 3pm" or "at the party").
• In is wrong—"in" refers to longer time periods ("in summer," "in 2024"), not occasions.

Why A (to) is correct:
"Going to" is the standard phrasal verb for traveling toward a destination. You use "to" to show direction or purpose.

Why the others are wrong:
- B (in): "In" describes being inside a place, not going toward it ("I am in the supermarket" works, but not "going in")
- C (at): "At" shows a specific location ("I'm at the supermarket"), not the action of traveling there
- D (on): "On" doesn't work with "going" for destinations; it's used for surfaces or modes of transport ("on the bus")

A. on ✓
Use "on" when something rests on top of a surface. The book is sitting on the table's surface.

B. in ✗
"In" means inside a container or space. The book isn't inside the table.

C. at ✗
"At" indicates a general location or direction. It doesn't show the book's relationship to the table's surface.

D. for ✗
"For" shows purpose or direction toward someone/something. It doesn't describe physical position.

A. about ✓ Correct
"Talk about" is the standard phrasal verb in English. You discuss or mention topics using "about."

B. in ✗ Wrong
"Talk in" refers to the language or manner of speaking (e.g., "talk in French"), not the topic being discussed.

C. at ✗ Wrong
"Talk at" means to speak to someone without listening to them (one-way communication), not to discuss something together.

D. for ✗ Wrong
"Talk for" isn't a common phrasal verb for discussing topics. It can mean to speak on behalf of someone, but that doesn't fit here.

A. with ✓
"With" shows she's accompanying her friends—they're going together. This is the correct preposition for showing companionship.

B. in ✗
"In" describes location or position inside something ("in the car," "in the room"), not companionship.

C. at ✗
"At" shows a specific place or point, but doesn't express the idea of going together with people.

D. for ✗
"For" means intended to be given to someone or for a purpose, not for traveling together with someone.

Why A is correct:
"From" is the correct preposition to show where someone originates or comes from. "He is originally from France" means France is his place of origin.

Why the others are wrong:
- B (in): "In" shows location where someone currently is, not origin. "In France" means he's there now, not that he's originally from there.
- C (at): "At" is used for specific points or addresses, not countries or origins.
- D (for): "For" shows purpose or duration, not origin.

Why "for" is correct:
"For" is used with periods of time to show duration (how long something lasts). "He has been living in this city for five years" means he started living there five years ago and is still there.

Why the others are wrong:
- "in" – Used for months, years, or seasons as points in time ("in 2020"), not duration
- "at" – Used for specific times or locations ("at 3pm," "at home"), not time periods
- "on" – Used for days and dates ("on Monday," "on May 5th"), not duration

Correct answer: A (at)
- Use "at" with specific times (at 6 o'clock, at noon, at midnight). This is the standard English preposition for exact clock times.

Why the others are wrong:
- B (in) – Used for longer periods (in the morning, in 2024), not exact times
- C (on) – Used for days and dates (on Monday, on July 4th), not clock times
- D (for) – Used to show duration/length of time (for 2 hours), not arrival times

A. on ✓
"On" is correct because we use "on" with projects and tasks. "Working on a project" is the standard phrasal verb.

B. in ✗
"In" suggests being inside a location, not working on a task. You'd say "in an office," not "working in a project."

C. at ✗
"At" indicates a location or point in time. You might say "work at a desk" or "work at 9am," but not "work at a project."

D. for ✗
"For" shows duration or purpose. While "for" appears in the sentence later ("since morning"), it doesn't work here—you don't "work for a project."

Why A (in) is correct:
Use "in" when someone is inside a space or enclosed area. She is physically inside the meeting.

Why the others are wrong:
- B (at): "At" works for specific locations or events, but "in a meeting" is the standard phrase we use.
- C (on): "On" shows position on top of something or schedules (like "on Monday"), not being part of an activity.
- D (for): "For" indicates purpose or duration, not the action of participating in something happening now.

Why "at" is correct:
Use "at" for specific times of day (at 9 PM, at 3 o'clock, at noon).

Why the others are wrong:
- "in" – used for longer time periods (in an hour, in the morning, in 2024)
- "on" – used for days and dates (on Monday, on Christmas)
- "for" – used for durations/lengths of time (for 2 hours, for a week)

Why A (on) is correct:
"On vacation" is the standard English phrase. We use "on" with trips and time away from work/school.

Why the others are wrong:
- B (in): "In" is used for locations or time periods (in Paris, in summer), not for the act of taking a vacation
- C (at): "At" describes specific points or small locations (at home, at the store), not vacations
- D (for): While "for" can indicate duration (for two weeks), it doesn't pair with "vacation" the way "on" does—we'd say "on vacation for a week," not "go for vacation"
