Question

marcus is going through a particularly difficult time because of work - related stress, his parents health problems, impending final exams, and term paper deadlines. marcus has a history of not dealing well with stress. the continuous stress is likely to cause all these except:
cause marcus to develop cancer.
cause the blister on marcus foot to heal more slowly than normal.
weaken marcus resistance to a bad cold.
alter marcus immune system so that he does not fight off disease as well.

Explanation:

Stress can weaken the immune system, leading to slower wound healing (like a blister), reduced resistance to common illnesses (such as a cold), and altered immune function. However, while chronic stress may have an impact on overall health, it is not a direct cause of cancer. Cancer development is a complex process involving genetic, environmental, and lifestyle factors, not just stress alone.

Answer:

cause Marcus to develop cancer.
