Option B works as the increase in prices of shipping and handling risen by 15% would in fact negatively impact the profits, as the increased cost is an additional expense to the increase in water prices for irrigation.

So Option B does nothing to positively impact the conclusion i.e. to increase the profits by 15% but otherwise.

I was confused between A & B:

To me A doesn’t seem to also explain this paradox. If there are more producers how does it mean the profit will also increase?

Appreciate if someone can help explain this?

OFFICIAL EXPLANATION



The alfalfa industry requires comparatively large amounts of water. The past decade has seen both a steep rise in the price of water for agriculture and also a rise of 15% in overall profits in the alfalfa industry, even though the market price of alfalfa didn't fluctuate substantially.

Any of the following statements, if true, helps to explain the rise in profits EXCEPT



A. The number of alfalfa growers has grown by 25%.

Incorrect.

This is a Paradox Question, but one that asks you to choose the answer choice which does not help to resolve the paradox of the existing premises (all the others answer choices do):

    Premise A: There was a steep rise in the price of water for agriculture (expenses)

    Premise B: There was an increase of 15% in profits in the alfalfa industry

    Premise C: The market price of alfalfa hasn't changed much (i.e., no greater revenues because of price)

    Resolving Premise: ?

If some expenses are higher but there are higher profits in the industry, it means either that (a) revenues (=expenses+profits) are higher too; or (b) other expenses (=revenues-profits) are lower.

The question stem asks you to focus on explaining the rise in profits, therefore focus on premise B. Don't allow the first and third premise to distract you; think what else could explain the increase the amount of money made in alfalfa or lower the costs of alfalfa production... and eliminate all such answer choices.

A steep increase in the number of growers can explain why revenues (and therefore profits) are still high. You need an answer choice which does not explain the paradox.

Wait, but wouldn't an increase in supply actually drive down prices, and lead to lower profits?

It's true that according to economic theory prices are a function of demand, but we must be careful about making more assumptions than are necessary in solving this CR question. Remember the following:

a) The question belongs to the Profits/Revenues/Expenses type. Therefore, limit your reasoning to the application of this formula. Don't import another economic rule (in this case laws of supply and demand) which is not known to be utilized in CR questions.

b) Even if we were to assume that the grow in supply led to a price decrease, this would still not tell us whether the price decrease affected profits. It could always be that reduction of revenue due to price decreases was offset by the economy of scale, and did not affect profit adversely.

Because of these considerations, this answer choice is not the best of all the answer choices.



B. The price of shipping and handling has risen by 15%.

If the alfalfa growers are forced to pay more for getting their produce to markets, the paradox of the profits of the alfalfa industry growing by 15% is emphasized, not resolved.


C. The formation of the Alfalfa Growers Union has enabled alfalfa growers to obtain substantially lower prices for agricultural machinery.

Incorrect.

Don't allow the first and third premise to distract you; think what else could explain the increase the amount of money made in alfalfa or lower the costs of alfalfa production... and eliminate all such answer choices.

A substantially lower price for machinery, a major drop in expenses, could explain how profits grew despite higher water prices. You need an answer choice which does not explain the paradox.



D. A nationwide best-seller published at the beginning of the decade postulates a healthy diet, in which alfalfa is a staple.

Incorrect.

A nationwide best-seller telling people to eat alfalfa? Yep, this could definitely help explain higher revenues and therefore higher profits. You need an answer choice which does not explain the paradox.



E. New overseas markets for alfalfa have opened recently.

Incorrect.

The opening of new overseas markets could explain the rise in revenues and therefore in profits. You need an answer choice which does not explain the paradox.
