Question

another knowledge check, which means another chance to score some points! which of the following statements about recurring concussions is true? remember, you earn points for right answers, and you need at least 80 points to pass. after you fully recover from a concussion, its harder to get a second concussion. even if you fully heal between them, multiple concussions can cause long - term brain changes. getting a second concussion after recovering from your first is just as risky as getting a second concussion before recovering from your first. its impossible to fully heal from a concussion — theres always some residual damage.

Explanation:

After a concussion, the brain is more vulnerable, making subsequent concussions more likely. Multiple concussions, even with full - healing in between, can lead to long - term brain changes. Getting a second concussion before full recovery from the first is more dangerous than after full recovery. And it is possible to fully heal from a concussion in many cases.

Answer:

B. Even if you fully heal between them, multiple concussions can cause long - term brain changes.
