What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted?
| | A) The CG shifts forward when thrust and drag are reduced. |
| | B) When thrust is reduced to less than weight, lift is also reduced and the wings can no longer support the weight. |
| * | C) The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced. |

The explanation should read: The wording of the question is misleading. As currently stated with the word 'category' being singular, the answer would be [B] because the listed classes are all in one category. If the question were stated "... which are categories of aircraft?" the correct answer would be [A] because these are all separate categories of aircraft.
