Explanation for Question 46 From the Reading Section on the Official Sat Practice Test 8

Okay, so for number 46, it says in the second paragraph lines, 2 15 through 31, the discussion of short-term memory, 3 primarily functions to do what. 4 So, um, remember where they talk about the second paragraph, 5 they talk about basically his analogy of short-term memory. 6 Um, and remember, 7 we kind of wrote that down or two over here as our main idea. 8 Um, the purpose of giving us an analogy is so that 9 we can better understand what's really happening here. 10 So it's so that we can better understand how the Venus fly trap when 11 its hair gets touched, how it encodes information. 12 And so by relating it to something that we are very familiar with, 13 something like short term memory, it allows us to have a better understanding, 14 or it allows us people that aren't really into science. 15 It allows them to have an easier understanding of really how this works. 16 So any answer choice that talks about making it easier to kind of understand 17 what's really happening here.
