Answer:
1, 3, and 4. ( 1. It helps readers see Nick’s mom as a caring person. 3. It explains what Nick’s mother felt and thought. 4. It helps readers see Nick’s mom as a real person. )
Step-by-step explanation:
The dialogue is said by Nick's mom. So, the second one, "It shows what Nick thinks and feels.", is incorrect. However, the rest of them (aka 1, 3, and 4) are correct since they apply to Nick's mom.
Also I did the assignment on Edg and got it right.
