Select the most appropriate adverb to fill in the blank.
"Good books should be read again and _________."

Explanation of the Correct Answer:
· The sentence suggests repeated actions, meaning the missing adverb should indicate repetition.
· The word "again" perfectly fits because it means doing something one more time or repeatedly.
Other options:
· (a) Ever → Incorrect; means at any time, which does not indicate repetition.
· (b) Never → Incorrect; means not at all, which contradicts the meaning of the sentence.
· (c) After → Incorrect; means later in time, which does not indicate repetition.
Thus, the correct answer is (d) Again.
