Question

Change the underlined part at [5], if necessary:

• A. NO CHANGE
• B. Refusing to back, down,
• C. Refusing to back down,
• D. Refusing, to back, down,

Answer 1

Answer: (C)

Refusing to back down,

According to general rule, a comma must be used after an introductory clause that's followed by the main clause. Thus, option C is correct.

Option A is incorrect because the usage of comma after 'Refusing' is incorrect in this context.

Options B and D: A comma indicates a pause; using several commas in a sentence disturbs its intended meaning.

Thus, options B and D are incorrect.
