which question would be asked in a dichotomous key?\nhow long are the insects antennae?\nare the insects antennae longer than its head?\nare the insects antennae long or short?\nhow does the insect use its antennae?

Answer

Brief Explanations:

A dichotomous key uses yes/no questions (binary choices). The question "Are the insect's antennae longer than its head?" is a yes/no question. The other questions either ask for a measurement ("How long are the insect's antennae?"), a description without a clear binary ("Are the insect's antennae long or short?" - "long" and "short" are relative and not strictly binary in a dichotomous - key - context as it's better to have a comparison like with the head length here), or about function ("How does the insect use its antennae?").

Answer:

Are the insect's antennae longer than its head?
