Use the following to answer questions
Scenario I
Over 100 years ago,French educational researchers Alfred Binet and Theodore Simon developed the first intelligence tests to identify children in need of remedial education.Binet and Simon developed their test to measure what Binet termed natural intelligence,or a natural ability to learn dissociated from the effects of educational instruction.Using Binet and Simon's intelligence test,each child's score could be compared with age-norms to arrive at the child's mental age.Shortly after this pioneering work,Louis Terman developed the intelligence quotient (IQ) .There are two ways to calculate an IQ score.A ratio IQ is calculated by dividing person's mental age by their physical age and then multiplying the quotient by 100.A deviation IQ is calculated by dividing a person's test score by the average test score from their age group and multiplying this quotient by 100.
-(Scenario I) An 8-year-old who performs similarly to an average 16-year-old would have a ratio IQ of 200.Similarly,a 30-year-old who performs similarly to an average 60-year-old would have ratio IQ of 200.At the other end of the intelligence spectrum,a 10-year-old with intellectual challenges and a mental age of 5 would have a ratio IQ score of 50.Based on these examples,ratio IQ scores tend to lose their validity as a measure of intelligence when used with:

A) highly intelligent individuals.
B) individuals with intellectual challenges.
C) children.
D) adults.
