Quizplus · Accepted Answer

There are confounding variables present in Vanessa's reasoning that could be impacting her sleep. For example, she may be sleeping better on nights when she finishes studying earlier, rather than the presence of music. Therefore, her claim cannot be fully attributed to the music alone, and there is a potential flaw in her reasoning.
