Alex's low scores on the new test suggest that it may not be a valid measure of intelligence, as other tests have indicated that Alex is intelligent. However, it is possible that the test is a reliable measure, as Alex consistently scored 35% on it during multiple administrations. Therefore, the best choice is B, which suggests that the test may be reliable but not valid. However, without more information or further testing, it is difficult to determine with certainty the properties of the new test.
