Question

Quizplus · Accepted Answer

The statement implies that Suzie's mental age is 6, which is typical for a 6-year-old child. Mental age is a measure of intellectual development, which may or may not correspond to physical age. Option A assumes that physical age is at least 6, which is not necessarily implied by the statement. Option C is incorrect because mental age cannot be calculated by subtracting physical age from the normative age of intellectual functioning. Option D is also incorrect because mental age is not determined by simple division of physical age.
