A company has been hired to drill a well to mine for groundwater. The rock in the area is very hard, so the drill used must be able to pound the rock to break it apart. Fortunately, however, the groundwater is not too far below the surface, so a suction pump can be used to bring the water to the surface. What type of drill and pump should the company use?(1 point)

Given the scenario where the rock is very hard, the company should use a percussion drill to effectively break up the rock. Since the groundwater is not too far below the surface, a suction pump would be suitable for bringing the water to the surface.

From the options provided, the most appropriate choice is:

a percussion drill with a suction pump.

However, since this option is not explicitly listed, the closest match would be:

a percussion drill with a submersible pump.

The submersible pump can still effectively lift the water from the well since the groundwater is not too deep, and it complements the use of a percussion drill in breaking the rock.
