Bunuel
The Larynxtown industrial zone is infested with rats. The municipality introduced DDA poison, improving the situation, but resulting in the death of many Klacktop birds. To prevent the death of the Klacktops, DDB poison was introduced which resulted in the death of many Gellowtop frogs. Some of the public believe that
since the rat infestation poses a significant threat to the Larynxtown citizens' health, any measures, irrelevant of the harm caused to wildlife, must be taken to cease it. The industrial zone neighbors the habitats of certain wildlife species that are protected by law so
the introduction of poisons is probably not the solution to this particular infestation.In the argument given, the two portions in boldface play which of the following roles?
(A) The first provides support for the argument's main position; the second objects to this position.
(B) The first states a position that challenges that supported by the argument's conclusion; the second is evidence used to further support that conclusion.
(C) The first challenges the main position of the argument; the second gives support to that challenge.
(D) The first describes evidence that supports the argument's conclusion; the second is that conclusion.
(E) The first is a position that opposes that established by the argument; the second is a conclusion to the argument.
Official Explanation
The Larynxtown industrial zone is infested with rats. The municipality introduced DDA poison, improving the situation, but resulting in the death of many Klacktop birds. To prevent the death of the Klacktops, DDB poison was introduced which resulted in the death of many Gellowtop frogs. Some of the public believe that
since the rat infestation poses a significant threat to the Larynxtown citizens' health, any measures, irrelevant of the harm caused to wildlife, must be taken to cease it. The industrial zone neighbors the habitats of certain wildlife species that are protected by law so
the introduction of poisons is probably not the solution to this particular infestation.In the argument given, the two portions in boldface play which of the following roles?
(A) The first provides support for the argument's main position; the second objects to this position.
Incorrect.
This is a Boldface Type question, in which you are required to define the role of the two boldface sections in the argument. Read the argument and break it down using indicative words:
- Sentences 1-3 are premises because they report real, factual occurrences.
- The first boldface portion in sentence 4 is an opinion because it uses the word believe.
- The section that follows the reason conjunction since is a premise about the danger posed to citizens' health; the section that follows is the position of some of the public, their conclusion.
- The first part of sentence 5 is a premise because it gives us factual information about the location of the industrial zone and about the wildlife protection laws.
- The second boldface portion is the argument's conclusion because it is based on the given premises; the word probably also helps to establish it as a judgment.
To sum up, the argument introduces two positions / conclusions:
1) Use poisons (taken by the residents) and
2) Don't use poisons (as shown by the argument's final conclusion, which claims that the poisons are not the best solution).
After reviewing the breakdown, we can see that the first boldface portion opposes the argument's main position. You can immediately eliminate answer choices that incorrectly define the first boldface part; do not waste time reading the rest.(B) The first states a position that challenges that supported by the argument's conclusion; the second is evidence used to further support that conclusion.
Incorrect.
While this answer choice defines the first boldface part correctly, it defines the second incorrectly. The second boldface portion does not contain any evidence but is, in fact, a conclusion based on the provided evidence.(C) The first challenges the main position of the argument; the second gives support to that challenge.
Incorrect.
While this answer choice defines the first boldface part correctly, it defines the second incorrectly. The second boldface portion represents the main position of the argument. Therefore, the two boldface portions actually oppose one another.(D) The first describes evidence that supports the argument's conclusion; the second is that conclusion.
Incorrect.
While the first boldface portion includes evidence, it is not in support of the argument's conclusion. On the contrary, it supports the conclusion of some of the public which opposes to the argument's position. You can immediately eliminate answer choices that incorrectly define the first boldface part; do not waste time reading the rest.(E) The first is a position that opposes that established by the argument; the second is a conclusion to the argument.
Since the argument's conclusion is for position 2, it can be taken as the bottom line-argument's position. Since the first boldface supports using poisons, it can be taken as going against the argument's main position.
