question 20 of 20
which sentence should be revised to reduce wordiness?

a. equipped with a video camera, the robot in flight captures aerial views that provide a unique visual angle.

b. its movable wings allow the robot to accompany and film people or objects in motion, so it can film the action as it is happening.

c. guided by a remote control, the robot is able to hover in place as well as fly in all directions, which gives it flexibility.

d. this palm - sized robot has the appearance of a large motorized dragonfly.

Explanation:

To determine which sentence is wordy, we analyze each option:

• Option A: The phrasing is concise, describing the robot's function clearly.
• Option B: The phrase "so it can film the action as it is happening" is redundant because "accompany and film people or objects in motion" already implies filming the action while it occurs. This repetition makes the sentence wordy.
• Option C: The sentence is clear and concise, explaining the robot's movement capabilities.
• Option D: The description of the robot's appearance is straightforward and not wordy.

Answer:

B. Its movable wings allow the robot to accompany and film people or objects in motion, so it can film the action as it is happening.
