Final answer:
The strategic hint "Do not spin your wheels" is best summarized by taking a break from a difficult problem and returning to it later, allowing for a fresh perspective and more effective problem-solving progression. The correct option is B.
Step-by-step explanation:
The strategic hint "Do not spin your wheels" suggests that when facing a difficult problem, rather than continuing to work on it fruitlessly, it can be beneficial to take a break or move on to something else to avoid wasting time. Option B best summarizes this strategy: Often the best strategy in problem solving is to put a problem aside for a few hours or days. For example, if you are struggling with a problem involving long division with polynomials, set it aside and come back to it in a few hours. This allows your brain to reset and possibly come back with a fresh perspective on the problem. Applying problem-solving strategies should involve identifying knowns and unknowns and checking the reasonableness of the solution.
The strategic hint "Do not spin your wheels" means that you should not waste time and effort on a problem that you are unable to solve or understand. Instead, it is best to set the problem aside and seek help or take a break from it. For example, if you are struggling with a problem involving long division with polynomials, it is recommended to put it aside and either ask for help or come back to it after taking a break.
