Answer:

High reliability and low validity

Explanation:

It was stated that the children took the test twice and had similar scores, hence the test has high reliability because it produces the same or similar results under the same conditions. Validity is tested to see how the results of the study really measured what they were intended to, checking how the results is in line with concepts and theories, and if the results are reproducible. In this case, Allans contained only multiplication problems and hence has low validity.
