Experts seem able to break a problem into meaningful chunks.This strategy provides all of the following advantages EXCEPT for


A) making it easier to remember the various elements of the problem.
B) highlighting the organization of the problem's elements,making it easier to see the problem's structure.
C) helping in the identification of subproblems and therefore in the creation of subgoals.

B) he is likely to do well on the entire test.
C) we can make no predictions about whether he'll do well on other portions of the test.
D) he will score similarly if he takes other portions of the test today,but his score will likely be very different if he takes the test in a few months.

In some procedures,participants are helped by an interruption during their attempts at solving a problem.In explaining this effect,which of the following hypotheses seems LEAST plausible in light of the available evidence?


A) The interruption provides an opportunity for participants to gather further information about the problem.
B) The interruption provides an opportunity for frustration or fatigue to dissipate.
C) The interruption allows participants to forget their earlier approaches to the problem,thus enabling a fresh start.
D) The interruption allows an opportunity for participants to use means-end analysis to solve the problem.

Which of the following is NOT an advantage gained by visualizing a problem via a mental image?
