Rory is trying to identify a tree from one of its leaves. A question on the dichotomous key that he is using asks whether the leaf has 3-5 lobes or more than 5 lobes. Rory cannot tell whether the leaf in his hand has 5 or 6 lobes. What should Rory do to continue identifying the tree?
Look at other leaves from the same tree, and count how many lobes they have.
Skip this question, since one question does not make a difference.

Find a different dichotomous key to use that does not ask this question.
