Which sentences contain a restrictive clause? 1. We fed the kittens that we found in the shed. 2. My grandmother, who was growing crankier by the day, scolded him harshly. 3. This is the house that I grew up in. 4. Our teacher, who was always ready to share in a good joke, laughed with us.
1 and 3 seem to be the right answer because the others don't specify.
