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
Brief Explanations:
"Booms" can be ambiguous. Adding "or barriers" clarifies what the floating booms are, improving precision. Changing "large" to "big" doesn't enhance precision as they are similar in meaning. Changing "powered" to "run" is a minor word - change without precision - gain. Adding "or the sea" after "the ocean" is redundant since ocean and sea are related and the context already implies a large - water body.
Answer:
In sentence 4, add "or barriers" after "booms."
