Scientists have discovered a new species of butterfly that lives only in a small region of Central America and is active only at night. During the day, it rests in treetops, where its green color matches the foliage perfectly. Therefore, the scientists must have discovered the butterfly at night.
The argument depends on which of the following assumptions?
the OA was B
(B) CORRECT. In order for this argument to work, one has to assume that there is no way for the scientists to detect the butterfly during the day, despite its camouflage. If there is a way for the scientists to detect the butterfly during the day, the conclusion is no longer logical.
(D) Whether the foliage is completely green or partially green is irrelevant as to when it was discovered
