Test-retest reliability refers to the consistency of test scores over time. In this case, Carl's scores were very similar when he took the test again at age 10, indicating that the test has good test-retest reliability. Face validity refers to whether a test appears to measure what it is intended to measure, validity refers to the accuracy of the test in measuring what it is intended to measure, and test reliability refers to the consistency of test scores across different test-takers or situations, none of which are specifically addressed by Carl's test scores.
