Explanation:

First Question (True/False about Concussion Cause)

A concussion is a type of traumatic brain injury that can result from a direct blow to the head (like a hit) or an indirect blow (such as a whiplash - type motion that causes the brain to move within the skull). So the statement is true.

• CT scans and MRIs are not typically used to diagnose a concussion as they often don't show the subtle changes of a concussion.
• A "concussion test" is a bit vague, and the standard diagnosis involves observing two or more signs and symptoms (like headache, dizziness, confusion) that occur after a direct or indirect blow to the head.

Answer:

True
