Explanation for Question 49 From the Reading Section on the 2018 May Sat
For question number 49, we are providing evidence for the previous 2 question. Um, previous question would be number 48 based 3 on the passage. The authors would most likely say that conducting deep all sky 4 surveys to obtain information about ancient galaxies is unnecessary. 5 So we're looking for evidence that the scientists don't believe all sky surveys 6 are required to gain this important information about ancient galaxies. 7 So our correct answer, I believe should be located in the paragraph I 8 highlighted in the previous video. Let's take a look 9 So here mine's 51 through 58. 10 This paragraph is where they describe their experimental setup using 11 a smaller sample to sort of generalize to the full 12 universe of galaxies as a whole. So this setup where they talk 13 about how pollsters and medical researchers learn about a larger population 14 by studying fewer samples, shows that they believe this is a valid approach. 15 And therefore that a full scale study, 16 um, making the entire, all of these galaxies as their sample would be unnecessary 17 as addressed in the answer to question number 48. 18 So our correct answer here should be choice C lines, 19 53 to 58. That's this underlined portion here, 20 and that's going to be our correct answer, 21 53 to 58 choice. See our other answer choices. 22 A is lines 39 to 45 down here 23 where they'd just describe how candles became the largest 24 observing program undertaken by humble the telescope devoted 600 hours 25 to ...
