What chapter 3 covers

Ten English · Vocabulary questions with answers

Try each one, then open the answer. These ten stay the same; the test draws new ones every time.

1. Choose the word that best completes the sentence: "He is accused ______ stealing the exam papers."

  1. A
    for
  2. B
    with
  3. C
    about
  4. D
    of
Show answer

Answer: D. The verb "accuse" takes "of": accused of stealing. "Charged with" uses "with", which is the usual mix-up.

2. Choose the word that best completes the sentence: "The results were so ______ that the researchers repeated the experiment to be sure."

  1. A
    surprising
  2. B
    predictable
  3. C
    ordinary
  4. D
    expected
Show answer

Answer: A. Researchers repeat an experiment "to be sure" when the results are unexpected. The other three words describe results that would need no checking.

3. Choose the word most nearly opposite in meaning to FRUGAL.

  1. A
    thrifty
  2. B
    fruitful
  3. C
    extravagant
  4. D
    poor
Show answer

Answer: C. Frugal means careful not to waste money, so the opposite is extravagant. "Thrifty" is a synonym and "fruitful" only sounds similar.

4. Choose the word or phrase closest in meaning to AMBIGUOUS.

  1. A
    ambitious
  2. B
    precise
  3. C
    harmful
  4. D
    open to more than one meaning
Show answer

Answer: D. Ambiguous means able to be understood in more than one way. "Precise" is nearly its opposite, and "ambitious" is a look-alike.

5. Choose the meaning of the bold word: "The rules were applied arbitrarily, so no one knew what to expect."

  1. A
    strictly
  2. B
    fairly
  3. C
    without reason or system
  4. D
    in secret
Show answer

Answer: C. Arbitrarily means based on chance or personal whim rather than a reason or system, which is why no one could predict the outcome.

6. Choose the word closest in meaning to DILIGENT.

  1. A
    intelligent
  2. B
    hard-working
  3. C
    delicate
  4. D
    lazy
Show answer

Answer: B. Diligent means showing steady effort. It rhymes with "intelligent" but describes effort, not ability; "lazy" is the opposite.

7. Choose the word most nearly opposite in meaning to OBSCURE.

  1. A
    clear
  2. B
    vague
  3. C
    dim
  4. D
    confused
Show answer

Answer: A. Obscure means unclear or hard to understand or see, so its opposite is clear. Vague, dim and confused are close in meaning to obscure.

8. Choose the meaning of the bold word: "Her account of the accident was corroborated by two witnesses."

  1. A
    contradicted
  2. B
    exaggerated
  3. C
    recorded
  4. D
    confirmed
Show answer

Answer: D. To corroborate is to support or confirm a statement with further evidence. "Contradicted" is the opposite.

9. Choose the word that best completes the sentence: "His explanation was so ______ that even the youngest students understood it."

  1. A
    complex
  2. B
    vague
  3. C
    lucid
  4. D
    lengthy
Show answer

Answer: C. Lucid means clear and easy to understand, which explains why even the youngest followed it. Complex and vague would make it harder.

10. Choose the word that best completes the sentence: "It is high time we ______ the problem seriously."

  1. A
    take
  2. B
    took
  3. C
    have taken
  4. D
    will take
Show answer

Answer: B. "It is high time" is followed by the past simple to talk about the present: "it is high time we took".
