(C) to lower the underground water level and digging trenches
(D) that lower the underground water level and that trenches be dug
(E) that lower the underground water level and trench digging
Solution:
Parallelism
The engineering firm has proposed two things "installing pumps" and "digging trenches".
It cant be said that "pumps" are digging trenches.
In A, B, and D, parallelism has been violated through using phrases other than digging. Furthermore, in B it is suggested that pumps would dig trenches which is illogical.
Besides, in D, engineering firm has proposed installing pumps that lower and that trenches be dug is awkward.
In E, firm has proposed installing pumps and trench digging is not parallel. It should have been digging trenches. Hence, E is incorrect.
In C, firm has proposed installing pumps and digging trenches is parallel. Hence, C is the best choice.
