Answer:
The two claims that are supported by the source is claim 1 and 4
Step-by-step explanation:
Claim number 4 is supported by the source because it states at the beginning that sleepwalkers are usually operating under severe lack of sleep or have an irregular or hectic sleep schedule.
Claim number 1 is supported by the source because its states that stress, anxiety, medical conditions, and taking certain types of medications can cause a person to sleepwalk.
I hope this helps you. Have a blessed day.
