Question 7

To determine the t - cell count threshold for AIDS, we rely on medical knowledge. In the context of AIDS diagnosis, a person's CD4 + T - cell (a type of t - cell) count must drop below 200 cells per micro - liter of blood.

We analyze the meaning of the acronym "STI". In the field of health and medicine, "STI" is a well - known acronym. "Sexually Transmitted Infections" is the correct expansion of "STI". The other options, like "Sensually Transmitted Infections" and "Sexually Transmitted Intentions", do not match the standard medical definition of "STI".

Answer:

D. 200 cells/micro - liter of blood
