Answer to Question 1

ANS: A
Measurement of skin-fold thickness is an indicator of body fat. Arm circumference is an indirect measure of muscle mass. The accuracy of weight measurement should be verified with a properly balanced scale. Body fat is just one indicator of weight.

Answer to Question 2

ANS: C
Head circumference begins larger than chest circumference. Between ages 1 and 2 years, they become approximately equal. Head circumference is larger than chest circumference before age 1. Chest circumference is larger than head circumference at 2 1/2 to 3 years.
