Which sentence should be revised to reduce wordiness? a. this palm-sized robot has the appearance of a large motorized dragon fly . b. equipped with a video camera ,the robot in flight captures aerial views that provide a unique visual angle. c. guided by a remote control ,the robot is able to hover in a place as well as fly in all directions ,which gives flexibility d. its moveable wings allow the robots go accompany and film people or objects in motion ,so it can film the actions as it is happening.

The answer would be D. You would want to break it up into 2 sentences at least. Hope this helped at least.  ↖(^ω^)↗

faulty parallelism is a construction in which two or more parts of a sentence are equivalent in meaning but not grammatically similar in form.

the correct version of this faulty parallelism in the sentence is:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

the problem is the last sentence, the first two have a basic subject+verb+object structure.

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in all three sentences:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.
