A) the average male score was better than the average female score.
B) the students were simply guessing at the answers.
C) the average score on the test was 50 percent correct.
D) relatively few students' scores deviated extremely from the groups' average score.

The statement mentions that the scores form a normal curve, which means that the distribution is bell-shaped and symmetrical. In such a distribution, most scores tend to be near the average, and relatively few scores deviate extremely from the average. Therefore, option D is the best choice as it captures this characteristic of normal distributions. Option A cannot be determined from the given information, option B is unlikely given that the test is designed to measure mechanical reasoning, and option C assumes a 50/50 chance of guessing, which may not be the case if the test has multiple-choice questions with more than two options.
