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?

1. The newly discovered butterfly is not related to any other species of butterfly.

2. There is no way for the scientists to detect the butterfly during the day.

3. No other butterfly species lives in this region of Central America.

4. The foliage in the butterfly's habitat is completely green.

5. The butterfly cannot survive in areas outside of Central America.
OA, after some discussion.

Any reason why 'Foliage need not necessarily be green in order to match.' I think because of Foilage's green colour, scientists couldn't figure out the butterfly in day.
