Question

some scientists have the following hypothesis:
atypical signals from severed sensory nerves are the mechanism behind phantom pain.
scientists have tested this hypothesis in multiple studies. in each study, scientists worked with patients who felt phantom pain after amputation. scientists gave the patients shots of anesthetics, which are chemicals that block nerve signals. the anesthetics stopped the severed nerves from sending signals to the brain. then, the scientists asked the patients about their feelings of phantom pain.
click the blue words to correct the following statement.
if the scientists hypothesis is correct, blocking atypical signals will cause phantom pain. so, the hypothesis is best supported if some patients report that they feel phantom pain after receiving anesthetics.
submit

Explanation:

The hypothesis states atypical signals from severed nerves cause phantom pain. Blocking these signals (via anesthetics) should stop, not cause, the pain. To support the hypothesis, patients should report no phantom pain after anesthetics, so the incorrect words need replacement.

Answer:

If the scientists' hypothesis is correct, blocking atypical signals will stop phantom pain. So, the hypothesis is best supported if no patients report that they feel phantom pain after receiving anesthetics.
