Preposition MCQ (A / An / The) – Daily Practice Set with Answers

Explanation (in simple English):

• The correct sentence uses by to show the manner/means of ending the speech: “concluded his speech by stressing …”
• Rule: by + gerund expresses the way something is done or how it ends.
• Other options are wrong: with or in stressing is not idiomatic here; at stressing is incorrect in this context.
• Note: After “stress,” the common structure is to use the gerund (stressing) or to say “stress the importance of …”

Correct option: B to

• Reason: The verb “fight” can take the infinitive/aim sense with to to show purpose or goal (fought to defeat/overcome every kind of aggression).
• Why others are wrong:

  • with — used for means or accompaniment, not for purpose here.
  • at — not used with this meaning in this context.

Correct option: B on

• Why: The phrasal verb "depend on" means to rely on someone or something. The sentence uses the fixed idea "stand on your own feet," so we say "depend on others."

  • D for: incorrect meaning

Explanation: The correct preposition is of in the phrase a lot of when talking about uncountable nouns like pleasure.

• Correct: Our life promises a lot of pleasure.
• Wrong: with, for, at do not collocate with "a lot" to modify "pleasure" here.
• Reason: "a lot of" + uncountable noun is the standard form; “a lot” is followed by of.

Correct option: C

• Rule: Adjectives like "good" are followed by at + a gerund (doing something). So, "good at making stories."
• Why others are wrong:
  • in — not the fixed collocation with "good" + gerund.
  • about — not used to express skill.
  for — means usefulness, not skill: "good for" something else.

Correct answer: D. with

• Rule/usage: "Deal with" is a common phrasal verb meaning "to concern or deal with a subject." The sentence needs a preposition that links the subject (the author's familiarity and love) to the topic.
• Why D is correct: The phrase reads: "deals with the author's familiarity..." which is the standard collocation.

  • in/at/of are not used with "deals" in this sense.

"since" with the "Present perfect" describe an action or situation that began in the past and continues in the present.

Answer: D) at

• Rule: Use at with an address/location when giving where to send mail or correspondence.
• Why this fits: “Please write to me at this address” tells where to send the letter.
• Why others are wrong:
  • to: used for the recipient (who), not for the location.
  • on: used for days, dates, or surfaces, not addresses.
  • upon: outdated/rare, not standard for addresses.

Correct option: A
