Question

alan reluctantly decided to take a long - awaited trip to new zealand. the thing that is most disturbing to him is that he must leave his pet monkey behind. a \pet hotel\ in the city has agreed to take him. should alan worry about him? yes. monkeys under stress due to social disruptions have weakened immune systems. yes. monkeys under stress due to social disruptions tend to have increased lymphocyte production. no. monkeys like new social situations, and their immune systems are actually strengthened. not sure. no studies have been done examining social disruptions and monkey immune systems.

Explanation:

When animals experience social disruptions, it can cause stress. Stress in animals, including monkeys, is known to have negative impacts on their immune systems. Increased stress due to being separated from their usual environment (in this case, being left at a "pet hotel" away from Alan) can lead to weakened immune systems. Lymphocyte production is not increased in a positive way due to such stress - rather, the overall immune function is compromised. Also, there are studies indicating the negative effects of stress (including from social disruptions) on animal (including monkey) immune systems, so the claim of no studies is incorrect. And monkeys do not generally "like" new social situations in a way that strengthens their immune systems when it's a result of forced separation (like being left at a pet - hotel).

Answer:

Yes. Monkeys under stress due to social disruptions have weakened immune systems.
