Explanation for Question 31 From the Reading Section on the Official Sat Practice Test 8
Okay, so number 31 is actually based solely on the graph. 2 So we don't need to read the passage at all here. 3 Um, let's go back to, oh, actually wait one second. 4 So it actually says based on the passage and the graph, 5 so nevermind. You do have to read the passage to, 6 um, so which label on the graph indicates the point at which assault me 7 in a wire breaks. So let's go back to the graph first. 8 Um, okay. 9 Let's look at this. So 10 this is an interaction of the two with the solid surface. 11 Um, and this is the tip moving away from the cell surface. 12 So this is, would be the graph where things break, 13 because this is actually what you're moving toward. 14 Whereas this is when you're moving away. If you're moving away, 15 you're breaking. Right. So kind of where is that inflection point where you break? 16 Um, well, let's see. 17 The break would be where there's no more force, right? 18 If there's no more force, that means that you kind of broke off from 19 the other thing that you were attached to. 20 Um, so we see like, okay, the forest had going down, 21 down, down, down, down, and then bam, it drops like this. 22 This is the breaking point right here T um, 23 I'm not sure if there's any point in the passage where like that helps 24 you understand that more. Um, 25 I think it's over here. So yeah, the surface tension is so strong that 26 as a microscope pulls away from the salt again, 27 that proves that we're looking at this graph pulling away. 28 Um, the salt stretches the inside has no choice, 29 but to reprint the atoms rather than break. So they basically, 30 you like keep moving away, moving away with them away, moving away until you 31 reached rock and bottom, right until you get to zero force. 32 So there you go. The answer is going to be, 33 let's see, letter D, which is point T.
