Explanation for Question 31 From the Reading Section on the 2019 April Sat
For 31, we want to know which statement about reflectance patterns in monitor. 2 Sepsis Honorata is best supported by the data presented in figure one. 3 So here I have figure one, 4 we're looking at the reflectance patterns and let's just go through with the answer 5 choices until we find one that matches up. 6 So for a, the flower pedal reflectance pattern. 7 So here it is tracks closely with the bract reflectance 8 pattern, which is this one. So if we look here is the flower pedal. 9 Here is the BRAC. They are not tracking closely at all. 10 So a is not correct. 11 Now, if we look at B the leaf litter reflectance pattern. 12 So here is leaf litter shows decreases in relation 13 to increases in the flower pedal, 14 reflect this pattern. Here's flower pedal. If we only look at this 15 leaf litter graph right here, 16 it doesn't decrease at all. So B can't be correct. 17 Now we look at, see the reproductive stem reflectance pattern. 18 Just this one is most similar to the leaf litter reflectance pattern, 19 the solid line. So here's the reproductive stem and here is leaf 20 litter. They are not similar at all. 21 I would say that the reproductive stem is most similar to the flower pedal 22 graph, not the leaf litter graph. 23 So C is also not correct. 24 And that leaves D let's make sure it's correct though. 25 So the bract reflectance pattern differs substantially 26 from the reproductive stem reflectance pattern. 27 So here is Brecht here is reproductive SEM, 28 and we can see that they are very different. 29 So D is going to be the correct answer.
