Answer:

is reliable but not valid

Explanation:

Here, the test will show the vocabulary of a student every time a student takes the test. This means that the test is reliable i.e., the results are repeatable.

However the test will in no way indicate the instrument that they are suited for. This means the test is not a valid test in order to know what instrument is best suited to the student.

Hence, the test is reliable but not valid.
