The doctor suggested that the patient taking it easy inside of three months.	The doctor suggested that the patient to take some vacations for three months.
Correct Answer: The doctor suggested that the patient take things easy for at least three months.

3. John did not do well in the class because ____________

he studied bad.	he was not good study wise.
he was a badly student.	he failed to study properly.
Correct Answer: he failed to study properly.
Explanation: Choice (A) is incorrect because the Verb ‘studied’ should be modified by an adverb, ‘badly’. Choice (B) is in error because it is never correct to say ‘wise’ with a noun or verb to mean ‘in relation to’. Choice (C) uses ‘badly’, which is an adverb and cannot modify the noun ‘student’; it should have been ‘bad’. Choice (D) is correct in all sense.

4. Choose the correct sentence:

A good student must know how to study effectively.	A good student must know the way of efficiency in study.

8. ____________ the best car to buy is a Mercedes Benz.

Because of its durability and economy,	Because it lasts a long time, and it is very economical,
Because of its durability and it is economical,	Because of its durability and economy wise it is better than all the others
Correct Answer: Because of its durability and economy,
Explanation: Choice (A) contains correct parallel structure: durability (noun)… economy (noun). Choice (B) is verbose: ‘lasts a long time’ means it is durable. It is not necessary to us so many words. When there is a shorter answer that means the same and is grammatically correct, choose the shorter answer. Choice (C) would be correct if it said: “its durability and economy” (noun & noun). Choice (D) uses ‘economy-wise’. It is always incorrect to use ‘wise’ with a noun in this way.

when he had sixteen years	when sixteen years were his age
at the age of sixteen	at age sixteen years’ old
Correct Answer: at the age of sixteen
Explanation: There are only a few possibilities for expressing age in English. (1) When he is sixteen (years old). (2) at (age) sixteen, and (3) at the age of sixteen. Choice (C) follows the rule (3) and is the only correct answer.

17. The Starks were told to ________.

talk all they wanted	make lots of expressions
speak freely	talk with their minds open
Correct Answer: speak freely
Explanation: Choice (A) is verbose and too informal for written English. Choice (B) uses ‘make’ and it does not make any sense. In choice (D) with their minds open (having open minds) is an idiom meaning to be willing to have no biases. When used in this context with ‘talk’, it is not logical.

18. Those students do not like to read novels__________their textbooks.

in any case	forgetting about
leaving out of the question	much less
Correct Answer: much less
Explanation: ‘Much less’ is used in this context in a negative sentence to indicate that the second item mentioned is disliked even more than the first. The students dislike reading novels and dislike reading textbooks even more.

19. He _________ looked forward to the new venture.

eagerly	with great eagerness
eagernessly	in a state of increasing eagerness
Correct Answer: eagerly
Explanation: Choices (B) and (D) are verbose. ‘Eagerly’ (A) is much more concise than either of these choices. Choice (C) uses ‘eagernessly’, which is not a word. It is not possible to add an adverb affix (-ly) to a noun affix (-ness).

20. The people were told to vacate their houses immediately ___________.

in the time when the water raised	when the water began to rise
at the time when the water began to go up	when up was going the water
Correct Answer: when the water began to rise
Explanation: Choices (A), (C), and (D) are all verbose. In addition, choice (A) includes the wrong verb (raised); (A) and (D) incorrectly use ‘the time’ as well as ‘when’. So, choice (B) is the logical answer.
