Answer to Question 1

2,4,5
Rationale: The body's buffering system is more base than acid, due to the strong tendency toward acidity because acids are continually produced during metabolism.

Answer to Question 2

3
Rationale: Mononucleosis is spread through contaminated saliva, so it is important to avoid kissing or contact with the infected person's saliva until the infection is resolved. Handwashing also helps to reduce the spread of the disease if the hands have been contaminated by infected saliva.
