Answer to Question 1

ANS: C
Linear growth or height occurs almost entirely as a result of skeletal growth and is considered a stable measurement of general growth. On average, most children have doubled their birth length at age 4 years. One and 2 years are too young for doubling of length. Most children will have achieved the doubling by age 4 years.

Answer to Question 2

ANS: B
The growth velocity after age 7 years is approximately 5 cm (2 inches) per year. One inch is too small an amount. Three and 4 inches are greater than the average yearly growth after age 7 years.
