Question

Quizplus · Accepted Answer

Bats are nocturnal animals, so opening at night would be the best way for a flower to attract them. Insects, on the other hand, are commonly active during the day and may not be attracted to a flower that only opens at night.

Answer: B
 Bats are attracted to sweet smells, so producing a sweet scent would be a way for a flower to attract them. Insects may also be attracted to sweet smells, but they may also be attracted to other types of scents, such as musky or floral scents.

Therefore, the answer is either A or B, or both.
