Question

combination wrenches a combination wrench combines a box - end and an open - end together in one tool. both ends are the same size. this tool combines the advantages of both box - end and open - end designs: a relatively large force can be applied using the box - end, while the open - end allows for greater speed in hard to reach places. which advantage of the box - end is combined with the ability to work quickly? the box - end enables the user to transfer a relatively large force to a bolt or nut. the box - end provides the ability to tighten a bolt with a small force. the box - end allows easier access to difficult or inaccessible nuts and bolts.

Explanation:

The text about combination wrenches states that the box - end allows a relatively large force to be applied, and the open - end allows for greater speed. So the advantage of the box - end combined with the ability to work quickly (from the open - end) is the ability to transfer a relatively large force. The second option says tightening with a small force, which is incorrect. The third option about easier access is the advantage of the open - end, not the box - end.

Answer:

The box - end enables the user to transfer a relatively large force to a bolt or nut.
