Explanation for Question 49 From the Reading Section on the 2017 April Sat
Question number 49 asks scientists who specialized in lignum were useful to 2 Martin and asked of us, because why, 3 so specialization, like then we're going to take a look back at the passage 4 to see kind of where that comes up exactly and how the scientists 5 might've contributed to the original research project. 6 So looking at our passage, 7 um, and this bottom of the first column, 8 we see that, um, initially home 9 was kind of working alone, then brought on this collaborator, 10 um, who was able to examine the joints and find these secondary cell walls. 11 That's when they decided to seek out these experts in LinkedIn. 12 So this is kind of the beginning of the, 13 um, the answer choice that we're looking for there, 14 they're seeking out experts in LinkedIn because they examined the joints of, 15 um, these different units in the seaweed and saw secondary cell walls, 16 which were features commonly found in land plants. 17 So there were sort of this curious finding that led them to bring on 18 experts and lignin.

Um, so looking at our answer choices, 22 ISS, the toughness made it difficult to analyze so that the use of specialized 23 chemistry, um, this is incorrect. 24 They weren't looking for information about, 25 um, analysis with specialized chemistry. 26 They kind of alr...
