Answer

Brief Explanations:

A restrictive clause is essential to the meaning of the sentence and is not set off by commas. In the first three sentences, the under - lined clauses are restrictive as they are necessary to identify the nouns they modify ("books", "girl", "items"). In the fourth sentence, the clause "which had its grand opening two months ago" is non - restrictive as it is set off by commas and gives additional information about the "restaurant" that is not essential to identify it.

Answer:

The books that are stacked neatly on the top shelf belong to my great - grandfather.; The girl who broke the downstairs window with a baseball is knocking on the front door.; The store allowed the items that were purchased less than thirty days ago to be returned.
