Explanation for Question 43 From the Reading Section on the 2021 March Sat
All right now, looking at our final passage of this March, 2021 exam 2 for the reading section. Let's look at question number 43. 3 The question asks us do the result of the survey described in passage one 4 support the conclusion that there are twice as many Jupiter mass free-floating planets as 5 earth mass ones. So we're looking for passage one and these 6 earth mass planets and how many there are, 7 um, when we kind of skim through this first passage, 8 we'll see that, um, 9 there is some discussion of Jupiter mass planets earlier in the passage. 10 Um, this is the reference to lower mass planets like earth. 11 And it says the survey is not sensitive to planet smaller than Jupiter and 12 Saturn. So because earth is smaller than Jupiter and Saturn, 13 we can kind of guess that the survey isn't going to be sensitive to 14 those lower mass planets. Um, 15 so as a result, if it's not sensitive to those planets, 16 it wouldn't make sense for them to actually have generated account. 17 So because the survey isn't sensitive to those smaller planets, 18 we don't actually know how many there are. 19 Um, and that best aligns with the answer choice. D are there have twice 20 as many Jupiter mass planets? Well, 21 we can't really say because the survey does not include direct information about earth 22 mass free-floating pine nuts. In fact, 23 it actually goes so far to say, as the study can't really detect them. 24 So for that reason, we can't really weigh in conclusively on those question and 25 we'll select answer choice state.
