The money spent developing a particular software application does not accurately reflect the quality of the application. If it did, the software with the lowest development costs would also be the worst performing and least reliable. In fact, when figures are adjusted to include a number of different worldwide markets, technology experts have found that some of the companies that spent the most money developing their software actually produced much of the software that was considered lowest in quality.

Assuming the statements above are true, which of the following can be inferred from them?

(A) Companies that spend very little to develop products are often very successful.

(B) Development managers for the companies that spend the most on software development often lose sight of important details because of the high volume of work that they oversee.

(C) Increasing spending on the development of a software application will not necessarily result in an improvement in the quality of that application.

(D) Different worldwide markets are equally likely to rate the quality of a expensively developed software application as "low."

(E) The highest quality applications are rarely the most expensive to develop.

The correct answer is c. Based on the premise saying that "some of the companies that spent the most money developing their software actually produced much of the software that was considered lowest in quality" we can infer that spending more money on the development of an application does not have to increase the quality of this application.

OA is C

OE is

The argument decouples money spent on software development and the quality of the software produced by telling us that some of the companies that spent the most money developing their software actually produced some of the software that was considered lowest in quality.

Choice C is correct. It draws a valid inference based upon the evidence in the argument: Since some of the companies that spent the most money developing their software actually produced some of the software that was considered lowest in quality, increasing spending would not necessarily make any improvement in the software's quality.

Choice A draws an an invalid inference. We know from the argument that some of the companies who spent the most on software development nonetheless produced some of the worst quality software. Even if this statement applied to all companies that spend high amounts on software development, this answer choice would be assuming that its inverse is true, an invalid formal logical inference.

Choice B states a possible explanation for why some companies might produce low quality software despite spending large amounts of money on development. While this explanation may seem to make logical sense, it cannot be validly inferred from the information in the argument.

Choice D states that different markets are equally likely to rate an expensive software product as being of low quality. This cannot be inferred from the argument. In fact, the opposite can be inferred: Because the figures must be adjusted to include other markets, the implication is that different worldwide markets have different ratings for software products. Otherwise, there would be no point in adjusting [the rating figures] for different worldwide markets.

Choice E states that the highest quality applications are rarely the most expensive. We can conclude from the argument that the highest quality applications are not necessarily the most expensive, but it is too extreme to say that they rarely are.

Choice C is correct.
