Read the source information below: “What is Sleepwalking?” by Matt Valerio Sleepwalking is a sleep disorder that causes a person to get up and walk while still asleep, usually during the deepest states of sleep. While sleepwalking, a person does not often respond when someone asks a question or touches him or her. Though sometimes a sleepwalker will verbally respond, the response will make no sense. A sleepwalking episode can include the person just walking quietly around a room or demonstrating very agitated behavior and trying to “escape” the room.

Which claim is supported by the source above?

Some outside influences make a person more likely to sleepwalk.

If your mother was a sleepwalker, it is more likely that you will be, too.

When people are sleepwalking, they are not aware of their surroundings.

Going to bed at the same time every night can help some children not sleepwalk.
