Question

based on reports from patients, scientists estimate that as many as 80% of people with amputations experience phantom pain. although this pain is common, scientists do not yet fully understand the mechanisms, or processes in the body, that cause phantom pain.
because scientists do not understand what causes phantom pain, it is difficult for them to figure out how to stop it.
what will be possible when scientists better understand the mechanisms behind phantom pain? select the best prediction.
scientists will be better able to prevent limbs from being removed in the future.
scientists will be better able to find treatments to stop the processes in the body that cause phantom pain.
scientists will be better able to determine the number of people who experience phantom pain.

Explanation:

The text states that scientists cannot stop phantom pain because they don't understand its causes. If they better grasp the mechanisms, they would be able to develop ways to stop the pain-causing processes. The other options are not supported: preventing amputations is unrelated to understanding phantom pain mechanisms, and the number of affected people is already estimated.

Answer:

Scientists will be better able to find treatments to stop the processes in the body that cause phantom pain.
