In which phrase does the writer most need to improve the
word choice for clarity?
Read the passage
Another drawback of the driverless car is the way it handles
things on streets. In one example, a driverless car couldn't
respond to a police officer's hand signals when he waved for
it to stop at a green light. In another situation, the car was
confused by a tumbleweed blowing across the road.
O way it handles things on streets"
o "police officer's hand signals”
O "to stop at a green light"
O "tumbleweed blowing across the road"

O way it handles things on streets

Explanation:

There is a needless ambiguity in this phrase that would just confuse the reader. it is not good prose when you can use just as many words and explain what the problem is but instead just use the word 'things' to describe them.

The sentence begs to understand what exactly it is that the car does not understand on the road or has a difficulty to follow but this is left unanswered in the text of the paragraph.

So this  is where the author must re question their word choice for the passage.
