An experiment will be conducted to determine whether children learn their multiplication facts better by practicing with flashca
rds or by practicing on a computer. Children who volunteer for the experiment will be randomly assigned to one of the two treatments.

Why will it be impossible to conduct a double-blind experiment?A. The experimenter will know whether the child is a boy or a girl and whether he or she used flash cards or the computer.B. The child will know whether he or she is a boy or a girl.C. The child will know whether he or she used flashcards or the computer.D. The person who grades the tests will know whether the child was a boy or a girl.E. The person who grades the tests will know whether the child used flashcards or the computer.
