Explanation for Question 25 From the Reading Section on the 2018 May Sat
Question number 25 says which choice best describes how the team 2 achieved the results discussed in this paragraph. 3 So how results were achieved is what we're looking for here. 4 So let's look at that sixth paragraph. We want to know what the experimental 5 process was here to generate these results. 6 So I kind of provided an overview of this in the video for the 7 first question of this passage, but here let's take a look. 8 Um, basically what the scientists did was they sequence the Geneva, 9 the genomes of 22 domestic cats. 10 That was kind of a step one, um, 11 sequencing these genes of domestic cats and uncovered genes that 12 changed as the cats kind of were domesticated over time. 13 Um, and then they found, 14 um, they found genes sort of in these other, 15 um, non domesticated cats that allow them to make a comparison, 16 um, that was sort of their second step. 17 And they used those two studies to draw conclusions about 18 the genetic components, 19 um, that are responsible for the domestication of cats that the components have changed 20 as that process of domestication took place. 21 So looking at our answer choices as sequence genomes of 22 breeds 22 compared to each other, and then identified the genes that appear to change as 23 a result of breeding, the key here is a result of breeding. 24 That's not what we're focusing on. We're focusing on evolution and domestication B 25 says the team used a previously published genome sequence to locate the genes assoc...
