Explanation for Question 19 From the Reading Section on the 2021 March Sat
Question number 19, according to the model and figure one, 2 the number of Twitter posts on the relevant topics in excess of the average 3 followed what trend. So looking at model one, 4 we see that this figure, 5 um, describes the number of posts that are kind of being made 6 as a function of the days following publication. 7 So, uh, every kind of day that's passed since the publication 8 of the new story, how many posts were generated on 9 that topic? We said, there's kind of this downward trend. 10 So as the number of days increases, 11 the number of posts is going down. 12 So more days in the future means less posts kind of at an even 13 rate dropping off a little bit more and more every day. 14 So when we look at our answer choices, 15 this kind of best aligns with answer choice D um, 16 the amount of Twitter posts in excess of the average decrease throughout 17 days one through six, following the publication. 18 Um, our other choices increased. 19 Um, definitely not the case. We saw that downward trend. 20 Um, B was approximately zero by day three. 21 Um, that's not the case because we can actually see that day three 22 would have been more like 2,500, 23 definitely not zero. Um, 24 and answer choice C was greater than zero for two weeks. 25 Following the experimental new stories publication. 26 The key here is that two weeks figure this data actually only goes through 27 six days in the future. So we wouldn't want to make any comments about 28 what happens further than that in the future. 29 And we eliminate choice C leaving answer choice, 30 D as our best answer for question number 19.
