Millie is stumped by a problem in her pre-calculus text. She furtively glances at the answer provided in the back of the text to get an idea of how the solution should look before she returns to the problem. Millie's strategy most closely resembles the problem-solving heuristic of:.a. working backward.
b. trial and error.
c. forming subgoals.
d. insight.

a. working backward.  

Explanation:

Working backwards: In psychology, the term "working backwards" is considered as one of the different types of heuristics and is described as a problem-solving method whereby a person imagines or thinks that he or she has solved a specific problem which he or she was trying to solve for quite a while.

Through the process of analyzing or imagining that the person has already solved a specific problem, he or she can then "work backwards" in his or her mind and therefore becomes capable of visualizing a particular solution to the given problem.

In the question above, Millie's strategy most closely resembles the problem-solving heuristic of "working backwards".
