An experiment was designed to test a hypothesis that stated that high-drive subjects would be able to learn a simple task much more quickly than would low-drive subjects. The hypothesis further stated that on a difficult task the opposite result would be found -- low-drive subjects would learn the task more quickly. The experiment's operational definition of drive was each subject's score on the Manifest Drive Scale. Twenty people who scored high on the scale (high-drive) and 20 people who scored low on the scale (low-drive) were given a difficult task to learn. The low-drive group learned the task more quickly that did the high-drive group, and the experimenter concluded that the hypothesis was correct.

You are to specifically, identify each study's IV(s), the IVs' levels, the DV(s), the type of design (i.e., between-subjects, within-subjects, and/or factorial), and the design problem of the study. Also be clear why the design problems are problems, and how they should/could be corrected. Each discussion should be about a paragraph.
