Avis put off writing her term paper until three days before it was due. "It's not that big of a deal. I can whip it out in a couple of hours," she thought. As it turned out, this was not the case. She averaged two hours a night sleep as she struggled to write the paper and turn it in on the due date. Once the project was submitted, she returned to her dorm room and collapsed into a deep sleep. Research has shown that she will:

1. sleep fitfully for several nights.
2. spend more time in REM sleep than she normally does.
3. suffer a brief period of short term memory loss as a result of the sleep deprivation.
4. suffer an extreme but temporary dip in her immune system.

I think 2.

2 is right.

To determine the correct answer, let's analyze the situation and use reasoning based on the information provided.

In the given scenario, Avis put off writing her term paper until three days before it was due. She then struggled to write the paper, resulting in only averaging two hours of sleep per night. Once the project was submitted, she returned to her dorm room and collapsed into a deep sleep.

Based on this information, it is likely that Avis experienced a significant amount of sleep deprivation. When individuals are sleep deprived, their sleep cycles can be affected, particularly the amount of REM (Rapid Eye Movement) sleep they get. REM sleep is a stage of sleep associated with dreaming and plays a crucial role in cognitive functioning and memory consolidation.

Given that Avis only averaged two hours of sleep per night during the period of writing her term paper, it is reasonable to expect that she would compensate for this sleep debt by spending more time in REM sleep once she finally got the chance to rest. Therefore, option 2, which states that she will spend more time in REM sleep than she normally does, seems to be the most accurate answer.

Note that while sleep deprivation can have various effects on the body, the scenario does not provide sufficient information to support options 1, 3, or 4 (sleeping fitfully for several nights, suffering from short-term memory loss, or experiencing an extreme dip in the immune system). Therefore, option 2 appears to be the most reasonable conclusion based on the information provided.
