Baddeley & Hitch (1974)report an experiment in which participants were to perform a reasoning task of various difficulty ("A precedes B" T/F? "B does not precede A" T/F? etc.).In addition to this primary task they were to repeat "the the the," repeatedly count from 1 to 6,or repeat a set of random digits.Performance was compared against single-task performance.
A)The dual-task demands affected each difficulty condition equally.
B)The dual-task demands of the verbal task did not affect reasoning performance.
C)The dual-task demands were particularly pronounced for the negative passive condition.
D)The dual-task demands were particularly pronounced when the second task was the random digit task,especially in the negative passive condition.

The experiment demonstrated that the dual-task demands were particularly pronounced when the second task was the random digit task, especially in the negative passive condition. This suggests that this type of secondary task places more cognitive load on the participants and interferes with reasoning performance, especially in more difficult conditions.
