Explanation for Question 43 From the Reading Section on the 2017 May Sat
Question 43 says based on the information in passage, 2 one, which area would be least likely to be colonized by a fast growing 3 invasive plant species. So we can look back into passage one and 4 look for evidence of where the author says anything about what would make certain 5 regions or areas susceptible to invasion by invasive plant species. 6 And we find that evidence right here in the second paragraph, 7 where it says that plant communities with lots 8 of disturbance, high resource availability, 9 or reduced a species diversity tend to be easily colonized. 10 So if we remember looking back at the question, 11 we're looking for the like scenario in which 12 the region would be least likely to be colonized. 13 So we're going to be looking for elements of the opposite of what's given 14 here. So we're given that lots of disturbance, 15 high resource availability or reduced species diversity lends itself to 16 being easily colonized. 17 So to be the least likely to be easy, 18 easily colonized we'd look for minimal disturbance, 19 low resource availability, or increased species diversity. 20 So if you read through each of the answer choices here, 21 we can start with answer choice a, it says a wetland area that was 22 recently converted to farmland, but now commonly experiences flooding and soil erosion. 23 So answer choice a is going to be an instance of high 24 frequency of disturbance. 25 And so that would be an easily colonized area. 26 And wouldn't be the correct answ...
