Explanation:

A claim is an arguable statement based on opinion. "Doctors say that 7 - 8 hours of sleep is necessary" is a fact - based statement (as it's a medical assertion). "Your brain needs sleep to function properly" is also a factual statement (a biological fact). "Students should go to bed before midnight" is an opinion - based statement that can be argued for or against.
