Answer: B. Periods of intense stress to be frequently followed by illness
Explanation: Too much accumulated stress primarily affects the collapse of the immune system and makes the body more susceptible to disease. As for the final weeks during the academic and school years, all the exams and many activities are tight and accumulated during those few weeks and there is always a lot of stress. A series of stress-related tasks that will be impossible to break and all of these responsibilities need to be answered for the exam, of course it causes a lot of stressful situations and rest during these weeks is not possible. After the end of this period, as with Mee Jung, rest comes, the accumulated stress will surely last for some time, and consequently, the mood is stressful and often due to a fall in immunity and the onset of illness.
