Identify the sentence that uses the verb mood in the indicative.

b.

c.

d.

C. It is impossible to sneeze with your eyes open.

Explanation: The correct sentence is indicative in its verb mood because it states a fact. Most sentences in English are in the indicative mood. They simply state a fact or give factual details.

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.
