I think the intent of the problem is that it wants to show that an equal and opposite force is being applied to the engine, therefore no forward movement is applied.
The way it is worded however causes those who a reading word for word to conclude that there is less than equal force being applied (because 1:1 with the wheel motion is that) and therefore the aircraft moves forward.
