Explanation for Question 32 From the Reading Section on the 2017 April Sat
Number 32 asks us which data presented in the table would 2 McKinnon find most useful to his argument. 3 So let's refresh our memory of McKinnon's argument. 4 Recall that McKennon was discussed earlier in the passage, 5 um, uh, 6 with reference to Sirius's lower density, 7 um, which is a high proportion for an asteroid, 8 but closely matches Pluto and other icy objects native to the outer solar system. 9 And he links this to the idea that it's likely that series probably formed 10 in Pluto's neighborhood. Um, so the key piece of evidence being used here is 11 actually the density, which is similar to Pluto, 12 um, kind of linking series to potentially being formed out there in the solar 13 system, kind of where Pluto is. So the data presented in the table that 14 best aligns with this is going to be answer choice. 15 A, the average density of Pluto is similar to that of series suggesting that 16 they were probably formed in a similar place in the series may be originated, 17 um, closer to where Pluto is in the outer edges of the solar system. 18 Um, details about, uh, location from the sun or mass or 19 density, um, are not going to be as relevant since McKinnon's findings really 20 hinge on, um, the density and the water ice content. 21 So that's why we're going to select answer choice. 22 A, the average density of Pluto being similar to series would kind of reinforce 23 McKinnon's argument better than any of these other, 24 um, pieces of data from the table. So choice a for number 32.
