Answer:
Intelligence tests should play no role in grading or marking practices
Step-by-step explanation:
This is because practice is an exercise or test on its own, and there should be a level playing field for every participant regardless of their IQ level prior to taking the practice. Hence, in this case, the right answer to the question is "Intelligence tests should play no role in grading or marking practices of participants," as this may lead to bias from the examiner.
