Answer to Question 1

D
Researchers have recently recognized that interferon and certain related cytokines are frequently produced by the body in response to some cancers and chronic inflammatory illnesses(such as rheumatoid arthritis). These substances appear to have a direct effect on the brain and may be responsible, at least in part, for depression that often accompanies malignancies and chronic illnesses.

Answer to Question 2

B
Studies of the brain seem to show that depression is associated with consistent changes in the temporal and especially the frontal lobes. Depressed persons do not metabolize glucose well in these areas, but when their depression resolves, the metabolism returns to normal.
