the disadvantages of group intelligence tests include thats:
a. all test takers must wait until all registered individuals arrive.
b. proctors are often insonsistent and allow some test takers a longer time to respond or to take testing breaks.
c. some test takers talk to themselves and distubs others.
d. some test takers are more motivated to perform at their highest level in a one-one testing situation.
Of the choices, D sounds best.
