Question

Choose the option that best fills in the blank:

You do not have to pay the fine _____ you return the book tomorrow.

• A. in order that
• B. so that
• C. on condition that
• D. as well as

Answer 1

Answer: (C)

on condition that

The speaker gives the listener an option, that if they return the book the next day, they would not have to pay the fine. "Return the book tomorrow" is the condition on the basis of which the listener won't have to pay a fine. "On condition that" also means the same, that refers to the condition, hence option C is correct. "In order that" expresses purpose in a sentence, but here the sentence is not purpose-related, it's condition-related. Hence option A is incorrect. Similarly, "so that" expresses purpose, the 'reason for which', and isn't relevant to the sentence, hence option B is incorrect. "As well as" is used to refer to an addition in a sentence, it plays the role of merely adding or connecting one clause or sentence to another, without modifying them. The clauses in the given sentence are not merely connected, but one of them "you return the book tomorrow" is the condition on the basis of which the action in the main clause "You do not have to pay the fine" is determined. Hence option D is incorrect.
