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?
Answer
A
Look at other leaves from the same tree, and count how many lobes they have.
B
Skip this question, since one question does not make a difference.
C
Start over from the beginning of the dichotomous key.
D
Find a different dichotomous key to use that does not ask this question.
