Quizplus · Accepted Answer

According to Siegler's first rule, the first thing a child would consider in a balance-scale problem is whether there are the same number of weights on each side of the scale. Therefore, Scott is likely to ask himself if there are the same number of weights on each side of the scale, making option B the correct answer. Options A, C and D are also relevant in balance-scale problems, but they are not the expected first step according to Siegler's theory.
