Answer to Question 1

Answer: b

Answer to Question 2

Answer: Precursor T cells leave the bone marrow (where they develop from the committed lymphoid progenitor cell) and enter the thymus through arterioles in the cortex. The thymus is the maturation compartment for T-lymphocytes. As they travel through the cortex and medulla, the T-lymphocytes interact with epithelial cells and dendritic cells, which provide signals to ensure that T cells recognize foreign antigen, not self-antigen. In addition, the T cells undergo substantial proliferation.
