Change this question into indirect speech. He said to me, "Where is your book"?

To change this into indirect speech, it would become "He asked me where my book is/was"

Hope this helps!

Explanation:

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.
