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 :-)

Please explain option D ? It seems so convoluted to me ..

Dear samichange,

I'm happy to respond. :-)

Here's the prompt with choice (D).
8) In virtually any industry, technological improvements increase labor productivity, which is the output of goods and services per person-hour worked. In Parland's industries, labor productivity is significantly higher than it is in Vergia's industries. Clearly, therefore, Parland's industries must, on the whole, be further advanced technologically than Vergia's are.

The argument is most vulnerable to which of the following criticisms?
(D) It takes a condition to be the effect of something that happened only after the condition already existed.


Yes, this is a bit hard to decipher. Many times, the incorrect answer choices on the CR Argument Structure question have this flavor: they are speaking at a very abstract level.

A condition is just some set of circumstances we find in the real world. It's anything that's factual. For example,
"In Parland's industries, labor productivity is significantly higher than it is in Vergia's industries."

To take a condition to be the effect of something ---- suppose I take the condition of a drought in California to be the effect of global climate change. Then I am saying global climate change is a CAUSE, and the drought in California is an EFFECT. To take a condition P to be the effect of Q: that is equivalent to the interpretation that Q caused P, that Q is the CAUSE and P is the EFFECT.

Now, my argument that "Q cause P" is going to run into trouble if it turns out that P was going on before Q ever existed. For example, suppose we have the following exchange:
Person A: "The price of tomatoes is very high. This must be due to the documentary last summer on the health benefits of lycopene, found in tomatoes."
Person B: "The price of tomatoes was high well before last summer."

Person B makes a devastating objection to Person A's argument.
Person A takes a condition (the high price of tomatoes) to be the effect of something (the documentary) that happened only after the condition (the high price of tomatoes) already existed. In other words, tomato prices were already before the documentary aired, so the documentary cannot possibly be the sole cause of the high price of the tomatoes.

For more practice with these question, see:

Does all this make sense?

Many thanks Mike for such an elaborate explanation.

Your explanation contains all that I was looking for.

Answer should be C.
It is clear from the argument that while making conclusion statement, author assumes that there could be no other explanation for the higher productivity.

(E) It makes a distinction that presupposes the truth of the conclusion that is to be established.

This is CR #8 in the OG13.


C it is because it presupposed a particular assumption and thought it is the reason for increase in Parland's industries .
He should have thought of other options.
Hence most vulnerable.

technological improvements(sufficient condition) -> increases in labor productivity( necessary condition)

Conclusion of the argument is a mistaken reversal for conditional reasoning

Conclusion: Parland's industries' has higher labor productivity than Vergia ->Hence Parland industries are technologically more advanced.

C is the only one that states the argument confuses sufficient condition for necessary condition( another way to state that the flaw is a mistaken reversal)

More technology = more productivity

Productivity in Parland > productivity in Vergia

Technology in Parland > technology in Vergia

A--No; the conclusion is the combination of the two premises, not simply a restatement of one of them.

B--I do not see any inconsistencies in the evidence.

C--correct; it is entirely possible that other factors have led to Parland being more productive. Better resources, more education, etc.

D--we don't really have information about timing here.

E--nope, no circular reasoning going on here.
