Question

Read the excerpt from a report.

(1) Stopping trash before it gets to the ocean is way better than having to clean it up in the ocean. (2) The city of Baltimore has a large machine called Mr. Trash Wheel. (3) The machine is powered by the sun and the flow of the river. (4) Floating booms off the front of the machine funnel garbage toward a conveyor belt. (5) The belt takes the garbage from the water and puts it in a dumpster. (6) The trash wheel helps collect garbage in the river after it flows out into the ocean

Which revision improves the precision of the text?

In sentence 2, change “large” to “big.”
In sentence 3, change “powered” to “run.”
In sentence 4, add “or barriers” after “booms.”
In sentence 6, add “or the sea” after “the ocean.”

Answer 1

C.) In sentence 4, add “or barriers” after “booms.”

Step-by-step explanation:

A.) is incorrect because "large" and "big" are synonyms. The word "big" is no more specific than "large".

B.) is incorrect because "powered" and "run" are synonyms. Again, the main idea is perfectly understood by the original word. No more additional context would be given if "run" was used instead.

C.) is correct because not everyone knows what the word "booms" means. By adding the word "barriers", more context is added. It allows the reader to better understand the mechanism.

D.) is incorrect because "ocean" and "sea" are very close synonyms. No more new information would be given in the statement is included.
