read the excerpt from a report. (1) cleaning up the existing garbage in the ocean would begin to address the issue of climate change. (2) a company called the ocean cleanup project has successfully developed a self - contained system that collects ocean garbage. (3) it uses the natural forces of the ocean to dump floating plastic. (4) the system consists of a thing, which holds a ten - foot screen below and catches the waste. (5) it would be awesome to have a bunch of these systems removing garbage. which revision improves the precision of the text? in sentence 1, change “address” to “impact”. in sentence 2, change “self - contained” to “one - of - a - kind”. in sentence 3, change “ocean” to “sea”. in sentence 4, change “thing” to “barrier”.
Answer
Brief Explanations:
In sentence 4, "thing" is a very general and imprecise term. Changing it to "barrier" makes it clear what the component of the system is, improving precision. Changing "address" to "impact" in sentence 1 doesn't improve precision regarding the action. Changing "self - contained" to "one - of - a - kind" in sentence 2 changes the meaning rather than improving precision about the system's function. Changing "ocean" to "sea" in sentence 3 is just a word - swap with no precision improvement as they are similar large water bodies.
Answer:
In sentence 4, change "thing" to "barrier."
