Question

Which of the following best represents the average rate at which infants grow in height during the first four years after birth?

A) 3 inches per month

B) 3 inches per year

C) 3 feet per month

D) 3 feet per year

Answer 1

The correct answer is B) 3 inches per year

C and D are nonsensical while A might seem correct but is actually the same as D when you do the math so it's also incorrect.

Answer 2

I believe the answer is: B) 3 inches per year

Humans tend to grow at a particularly slow rate until we hit our puberty. The growth rate could vary depending on nutrition and the genetic composition of the infants. Asian babies for example, grow at a slower rate with 2 inches - 2.5 inches per year.
