Evan is terrified because he is convinced that he has a terminal heart condition. he has consulted with several physicians who have found no evidence of any heart disease. evan continues to feel terrified even when the doctors find no physical problem. his diagnosis is probably

His diagnosis is probably Illness Anxiety Disorder (formerly known as Hypochondriasis).

Explanation:

Recently, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) redefined and modified what was previously known as Hypochondriasis into Somatic Symptom Disorder and Illness Anxiety Disorder.

In this case, Evan has probably Illness Anxiety Disorder, Care-seeking type. In contrast with Somatic Symptom Disorder, this focuses on the anxiety caused by the significance or outcome of the presumed illness, not by the somatic signs or felt symptoms.

As directly lifted from DSM-5, in order to diagnose this, the following criteria should be met:

Criteria A: Preoccupation with having or acquiring a serious illness.

Criteria B: Somatic symptoms are not present or if present, are only mild in intensity.  If another medical condition is present or there is a high risk for developing a medical condition (e.g., strong family history is present), the preoccupation is clearly excessive or disproportionate.

Criteria C: There is a high level of anxiety about health, and the individual is easily alarmed about personal health status.

Criteria D: The individual performs excessive health-related behaviours (e.g., repeatedly checks his or her body for signs of illness) or exhibits maladaptive avoidance (e.g, avoids doctor appointments and hospitals).

Criteria E: Illness preoccupation has been present for at least 6 months, but the specific illness that is feared may change over that period of time.

Criteria F: The illness-related preoccupation is not better explained by another mental disorder, such as somatic symptom disorder, panic disorder, generalized anxiety disorder, body dysmorphic disorder, obsessive-compulsive disorder, or delusional disorder, somatic type.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
