Imagine a Graph Showing Fluid and Crystallized Intelligence Scores as a Function

question 83

Multiple Choice

Imagine a graph showing fluid and crystallized intelligence scores as a function of age.Age appears on the x-axis,with increasing age toward the right.One curve portrays fluid intelligence scores; the other,crystallized intelligence scores.Which of the following statements best describes the relationship between the two curves as age increases?

• A)The two curves converge.
• B)The two curves remain parallel.
• C)The curves diverge: the slope of the fluid intelligence curve eventually becomes increasingly negative,whereas the slope of the crystallized intelligence curve does not.
• D)The curves diverge: the slope of the fluid intelligence curve eventually becomes increasingly negative,whereas the slope of the crystallized intelligence curve eventually becomes positive.
