Consumer health advocate: Your candy company adds caffeine to your chocolate candy bars so that each one delivers a specified amount of caffeine. Since caffeine is highly addictive, this indicates that you intend to keep your customers addicted.
Candy manufacturer: 0ur manufacturing process results in there being less caffeine in each chocolate candy bar than in the unprocessed cacao beans from which the chocolate is made.
Reading the argument, we see that the consumer health advocate's reasoning is that, since the company adds caffeine, which is addictive, to the chocolate bars, it's apparent that the company is seeking to keep customers addicted to the company's chocolate bars.
Then the candy manufacturer responds by saying that there is "less caffeine" in the bars than in the beans from which the bars are made.
A couple things might jump out at us with regard to the candy manufacturer's response.
One is that the fact that saying that there is less caffeine in the bars doesn't really serve to address the fact that the company adds caffeine. Sure, there's less, but even so, the fact that the company adds caffeine still appears to indicate that the company is seeking to keep customers addicted to the bars.
A second issue is that "less" is not the same as "little." So, while there is less caffeine in the bars than in the beans, there could still be in the bars a lot of caffeine, or at least enough caffeine to keep people addicted.
The candy manufacturer's response is flawed as a refutation of the consumer health advocate's argument because it
This is a Logical Flaw question, and the correct answer will accurately describe a way in which the candy manufacturer's response is flawed.
(A) fails to address the issue of whether the level of caffeine in the candy bars sold by the manufacturer is enough to keep people addicted
This choice may not be ideal because the main flaw in the manufacturer's response is not what this choice describes. Rather, the main flaw is that the response doesn't address the fact that it appears that the company wants to keep people addicted because the company adds caffeine.
At the same time, this choice works OK since it's true that, in saying that the bars contain "less caffeine" than the beans, the manufacturer fails to address the fact that "less caffeine" may still be enough caffeine to keep people addicted.
So, this choice accurately describes a flaw in the manufacturer's response.
Keep.
(B) assumes without warrant that all unprocessed cacao beans contain a uniform amount of caffeine
Notice that the manufacturer's response works regardless of whether all unprocessed cacao beans contain a uniform amount of caffeine. After all, even if they don't contain a uniform amount, it could still be that the company's chocolate contains less caffeine than the beans from which it's made.
So, since the response works even if it's not true that all unprocessed cacao beans contain a uniform amount of caffeine, the response does not assume that all unprocessed cacao beans contain a uniform amount of caffeine.
Eliminate.
(C) does not specify exactly how caffeine is lost in the manufacturing process
This choice accurately describes a characteristic of the candy manufacturer's response since it's true that the response does not specify exactly how caffeine is lost in the manufacturing process.
At the same time, this choice is not the correct answer since the fact that the response does not specify exactly how caffeine is lost in the manufacturing process does not make the response flawed.
After all, regardless of how the caffeine is lost, it's lost, and as a result there is, as the manufacturer says, less caffeine in the chocolate than in the beans from which it's made.
Eliminate.
(D) treats the consumer health advocate's argument as though it were about each candy bar rather than about the manufacturer's candy in general
This choice accurately describes a characteristic of the candy manufacturer's response since it's true that the response treats the consumer health advocate's argument as though it were about each candy bar.
At the same time, this choice is not the correct answer because the fact that the candy manufacturer's response treats the consumer health advocate's argument as though it were about each candy bar is not a flaw in the response. After all, the consumer health advocate's argument is indeed about the amount of caffeine in each bar.
Eliminate.
(E) merely contradicts the consumer health advocate's conclusion without giving any reason to believe that the advocate's reasoning is unsound
This choice is tempting because we may consider what the candy manufacturer says devoid of any good reason to believe that the advocate's reasoning is unsound.
At the same time, the truth is that, while what the manufacturer does not give any any good reason to believe the advocate's reasoning to be unsound, the manufacturer does give what the manufacturer considers a reason. After all, it appears that the manufacturer believes the fact that there is less caffeine in the bars than in the beans from which they are made to be a reason to believe that the advocate's reasoning is unsound.
So, even if that's not a good reason to believe the reasoning to be unsound, it is a reason that the manufacturer gives.
Thus, it's not accurate to say that the manufacturer contradicts the health advocate's conclusion without giving any reason.
Eliminate.
