Explanation for Question 21 From the Writing Section on the 2017 April Sat
Question number 21 says which choice provides the best transition from the previous 2 paragraph. So we want to make sure that our answer choice kind of touches 3 back on what was discussed in the previous paragraph while it introduces the new 4 subject of the new paragraph. So the previous paragraph here was talking 5 about, um, how beaver dams create 6 these ecosystems and the effect that they have on wetlands. 7 So in terms of increasing or decreasing the amounts of open water 8 via the creation of dams. So looking at our answer choices, 9 the no change option reads in addition to studying wildlife researchers are collaborating with 10 local officials. Um, this really puts the focus on the researchers, 11 uh, and doesn't touch on the beavers. So we don't want to select a 12 choice, eh, answer choice B despite the Beaver's reputation. 13 As a nuisance, researchers are collaborating with local officials to promote beaver populations. 14 Um, this focus on the reputation as a nuisance, 15 isn't really what's established in the previous paragraph. 16 So for that reason answer choice B is out. 17 Um, the previous paragraph actually talks about how beavers help ecosystems. 18 So it wouldn't make sense to characterize their reputation as a nuisance, 19 um, choice C spurred by these findings makes a lot of sense. 20 It connects the positive finding about beavers impact on ecosystems, 21 um, to the research that's being done here. 22 So it both touches on the previous paragraph and introduces the new idea. 23 Um, so answer choice C is correct, 24 uh, and D motivated by this opportunity. This again, 25 focuses on the researchers rather than the beavers who are discussed in the previous 26 paragraph. So for that reason, it's less of a strong answer twice then choice 27 C it's really important here to touch on the meaning of the previous paragraph. 28 Um, so focusing on the positive impact of beavers, 29 the choice, see here is correct.
