Explanation for Question 52 From the Reading Section on the 2017 May Sat
Question 52 says based on the information in the passages, 2 do the data and the graph better support the enemy released hypothesis or the 3 resource hypothesis. So the first thing we can do is look back and passage 4 one here to get a feel for what each of these hypotheses are predicting 5 specifically. And then we can look at the graph to see what information that's 6 giving us, and then what we can conclude based upon that information. 7 So the first thing we'll do is look back into passage. 8 One about these hypotheses. We can see that it says the enemy release hypothesis 9 attributes, the success of exotic diseases to their escape from or exotic species 10 to their escape from diseases and herbivores upon moving to a new range. 11 So for the graph to support this, we'd have to see something about diseases 12 or escape. The resource hypothesis suggests that plant invasion 13 is caused by the available availability of resources, 14 such as light water and soil nutrients. 15 So for the graph to support this, we'd have to see evidence of, 16 or some mention of a certain type of resource. 17 So if we look at the graph, then we can see that it says 18 the title is growth rates of native and invasive plants in a sauna and 19 desert during two growing seasons. So already right off the bat, 20 if we're looking at growth rates, this is probably going to be based on 21 resource availability. And we can confirm that based on the paragraph under it, 22 it says adopted from Sarah Kimb...
