Question

question 48
trephination is the ______.
technique that helps ensure the validity of experimental results
procedure where a large hole is created in the forehead so that evil spirits can escape
method that supposedly proved that the world is flat
theory that mental illness is caused by demonic possession

Explanation:

Trephination is a historical medical procedure involving creating a hole in the skull (including the forehead area in some cases) historically believed to let evil spirits escape. The first option is about experimental validity (not related), the third about proving the world flat (unrelated), the fourth is a theory of demonic possession for mental illness (not trephination). So the correct option is the one about creating a large hole for evil spirits to escape.

Answer:

B. procedure where a large hole is created in the forehead so that evil spirits can escape (assuming the options are labeled A, B, C, D with this as the second option; adjust label if needed based on actual numbering, but the text of the option is as stated)
