The argument is most vulnerable to which of the following criticisms?
(A) It offers a conclusion that is no more than a paraphrase of one of the pieces of information provided in its support.
(B) It presents as evidence in support of a claim information that is inconsistent with other evidence presented in support of the same claim.
(C) It takes one possible cause of a condition to be the actual cause of that condition without considering any other possible causes.
(D) It takes a condition to be the effect of something that happened only after the condition already existed.
(E) It makes a distinction that presupposes the truth of the conclusion that is to be established.


Hi, there. I'm happy to help with this. :-)

Of course, this is OG13, CR #8, a new question that did not appear in the OG12. Let's look at this prompt.

GENERAL RULE: In virtually any industry, technological improvements increase labor productivity, which is the output of goods and services per person-hour worked.
FACT/EVIDENCE: In Parland's industries, labor productivity is significantly higher than it is in Vergia's industries.
CONCLUSION: Clearly, therefore, Parland's industries must, on the whole, be further advanced technologically than Vergia's are.

We are told that technological improvements cause increases in labor productivity --- to use the language of formal logic, we know that technological improvements are sufficient for an increase in labor productivity. This is quite different from saying that: technological improvements are necessary for an increase in labor productivity. In other words, the argument is implicitly assuming that absolutely nothing else ---- labor conditions, local economic conditions, difference in shipping cost for materials or sale, etc. etc. --- would affect labor productivity. That's crazy. All kinds of other things also could affect labor productivity. Technological improvements are sufficient but not necessary for an increase in labor productivity.
Parland has higher labor productivity than does Vergia. One possible explanation could be a technological superiority, but again, there are a dozen other things that might differ between the two regions and might account for the difference in labor productivity.
The answer that best summarizes this flaw is (C) --- assuming that one particular cause is the only possible cause, or in other words, assuming that a sufficient cause is thereby also a necessary cause.

Does all this make sense? Please let me know if you have any further questions.

Mike :-)


Mike,
I am not sure what is wrong with answer choice D.

Does it say that the effect ( Technological advancement) causes the cause (Labor Productivity) ?

Mike,

Does it say that the effect (Technological advancement) causes the cause (Labor Productivity) ?

The argument is saying that:
CAUSE = technological improvements
EFFECT = increased labor productivity

Choice (D) does not reverse or change the order of fundamental causal relation. What choice (D) does is to introduce time. Choice (D) says:
It takes a condition (= increased labor productivity) to be the effect of something (= technological improvements) that happened only after the condition already existed

First of all, the argument gives absolute no information about time relationships, about what is before what. Furthermore, if technological improvements really are causing increased labor productivity. it simply makes no sense that labor productivity would have increased before any technological improvements. For these reasons, (D) is an unacceptable answer.

Does this make sense?

Mike :-)
