Answer Choices
A) The plants were unable to receive distress signals from infested plants through hyphal contact.
The plants had emitted a chemical that repelled the wasps that were attracted to infested plants.
The plants had developed hyphal connections with the fungi.
The plants’ root systems had become compromised by the aphids.
Explanation for Question 28 From the Reading Section on the 2018 April Sat
Hey guys. So question 28 says based on the passage, 2 which factor is most likely responsible for aphids attraction to some of the uninvested 3 plants in the experiment. So going back, 4 let's just remember what it tells us around here. 5 This says that in other words, 6 the volatiles from an infested plant attract wasps and repel, 7 aphids, meaning that these volatiles, 8 um, going on to an infested plant mean the aphids are scared away 9 because, um, and wasps are attracted wasps, 10 which are going to kill aphids. So when the plants aren't given this 11 infestation of these volatiles, when they're not given that, 12 then the aphids feel more comfortable going at them because the plant isn't able 13 to release this thing, that's going to call the wasps and repelled the aphids. 14 So what we seem to be seeing is, 15 um, that right there, and let's go through our answer choices and see which 16 fits to start at the bottom. 17 These are the plant's root system and become compromised by fits. 18 So we have no proof to believe that the plants or system was compromised 19 by aphids. It says that nowhere in the passage, um, 20 so it can be sure that's wrong. C says the plants had developed hyphal 21 connections with the fungi. So if the plants develop these connections with the fun 22 guide, that means there'll be more likely to be warned of the oncoming aphids 23 that they would release these certain things. But we know that that's not true 24 because they Fitz are more attracted...
