Marissa Wise · Answer 1

Presence or absence of the floral scent.

Explanation:

An explanatory variable is a type of independent variable. These are called explanatory variables because they explain the outcome of the experiment. In these case, if researchers found differences between the time that people take to complete the mazes, the explanation would lie with the presence or absence of the floral scent.
