The "Total Time" Hypothesis Proposes That the More Time Spent

The "total time" hypothesis proposes that the more time spent studying, the more people learn, with all other things being equal. Based on this hypothesis, a person can predict that if one group studies a list of words for 10 minutes and a second group studies the same list for 5 minutes, then the group studying for 10 minutes will learn:

A) more list words than the group studying for 5 minutes.
B) fewer list words than the group studying for 5 minutes.
C) the same number of list words than the group studying for 5 minutes.
D) no more list words than the group studying for 5 minutes.
