Answer to Question 1

ANS: B
Progression of human immunodeficiency virus (HIV) infection into AIDS is accompanied by a decrease in the number of CD4-positive cells (TH).

Answer to Question 2

ANS: C
CD34 is expressed on the surface of myeloid stem cells and blasts. CD4, CD8, and TdT are all markers of lymphoid lineage. In addition, TdT is not a membrane antigen but rather is found in the nucleus.
