Question

Which of the following sentences contain(s) a dangling modifier?

Answer 1

Answer:

The sentence that contains a dangling modifier is To raise a good dog, persistence is important.

Explanation:

A dangling modifier or a misplaced modifier is a word that is supposed to modify a word but because of its incorrect collocation in the sentences, it makes the general meaning confusing. The sentence To raise a good dog, persistence is important, needs to be modified in order to convey a clear message, since after the words To raise a good dog -which is the modifier-a noun is expected.

Answer 2

A dangling modifier is usually a phrase that is improperly placed in a sentence, and thus creates confusion because it doesn't really modify any word.
Having this in mind, the sentence that contains a dangling modifier is the first one - To raise a good dog, persistence is important.
The phrase to raise a good dog is a dangling modifier here, because it is not placed in the right location in the sentence.
