Answer to Question 1

B
Explanation: The pia mater is applied directly to the surface of the brain. The dura mater is the tough and fibrous outer layer. The subdural space is the space between the dura mater and the arachnoid layer. The arachnoid layer is a thin, delicate layer attached to the pia mater by web-like filaments.

Answer to Question 2

D
Explanation: Fibrin eventually becomes the meshlike blood clot; it does not convert platelets. The other statements are true.
