Task: Explanation
Input (English): Question: Harry was installing a TV mount. He drills into the wall with a screw that has 30 threads. If he used a screw of the same size with 20 threads, it would take _____ turns to put it in. 
 Answer: fewer
Output (English): The trade-off when the threads are closer together, is that more turns of the screw or bolt are needed to do the job because the distance over which the input force must be applied is greater.
