It all depends on how tricky the question is intended to be. If they really want to be devious then the effect on the take-off run depends upon the flap setting chosen.
With zero flap the lift-off speed will be high so it will take a long run to accelerate up to it.
With maximum landing flap set the lift-off speed will be lower but the drag will be much higher. So the acceleration rate will be dreadful. This will also require a long take-off run.
But at some flap setting in between zero and maximum there is an optimum angle which gives the shortest run. It is the angle at which the trade-off between increasing drag and decreasing lift-off speed is best. The value of this optimum angle depends on aircraft type (and probably a few other things).
