Explanation for Question 47 From the Reading Section on the 2018 May Sat
Question number 47 is asking us about the meaning of the word patch in 2 line 48. Let's see exactly how it is being used. 3 Line 48 is up here. 4 Um, each patch has been well-studied 5 from radio to x-rays giving plenty of complimentary data across the electromagnetic spectrum. 6 So patch here is pertaining to these five patches of 7 the Northern and Southern skies. So these are just different areas that are being 8 studied. Each patch is a particular area, 9 the sort of experimental unit that the scientists are drawing on. 10 Um, they're observing each patch, 11 each area, each region, sort of individually, 12 um, to, to discover what the, 13 um, remote galaxies look like. So we 14 should have for this question, answer choice D 15 region as our correct answer region area, 16 any of those kinds of words, that's exactly what patch is being used to 17 discuss here. It's important to just remember that patch is referring to these patches 18 of the sky in line. 19 Um, I believe 54, 55 that's being referenced by the author, 20 um, as the experimental units of this candles project. 21 Um, the other answer choices don't quite fit connection. 22 Um, patch could mean connection, but connection does not make any sense in this 23 context, if you plug that back into the sentence, 24 it won't fit. Um, allotment is sort of our easiest to eliminate that 25 doesn't work here, um, and see covering again, 26 like connection, a alternative use of the word patch, 27 but covering really has nothing to do with the current situation that we're looking 28 at in line 48. So for that reason, 29 our best answer to question number 47 is choice D region.
