Answer:
1. We fed the kittens that we found in the shed.
3. This is the house that I grew up in
Explanation:
Restrictive clauses have three main characteristics:
- They are adjectives, meaning that they modify or gives further detail of nouns.
- They are not set off by commas.
- They are essential to the full meaning of the sentence: Without a restrictive clause, the meaning of a sentence would change, or the sentence would be incomplete and vague.
Number 1 and 3 has all those characteristics because none of them are set off by commas, number 1 describes the noun "the kittens" and number 2 describes the noun "the house", and if these clauses were removed from the sentences, the sentences would seem incomplete.
