Answer to Question 1

4
Rationale 1: It usually takes a little longer than 2 months for transient strabismus to disappear.
Rationale 2: Transient strabismus lasts longer than 2 weeks.
Rationale 3: Transient strabismus generally does not last this long.
Rationale 4: Transient strabismus is caused by poor neuromuscular control of the eye muscles and gradually regresses in 34 months.

Answer to Question 2

4
Rationale 1: Sperm are produced in the seminiferous tubules in the testes, and are not affected by a vasectomy.
Rationale 2: A vasectomy does not affect motility or fertility of sperm.
Rationale 3: The sperm deteriorate, and are reabsorbed.
Rationale 4: Sperm cannot reach the outside of the body in a man who has had a vasectomy. The main function of the vas deferens, which is ligated in a vasectomy, is to squeeze the sperm from their storage site into the urethra.
