For the Past Several Years, A Certain Technology has been Widely Used to Transmit Data Among Networked Computers.

Question: Which of the following most logically completes the passage?

For the past several years, a certain technology has been widely used to transmit data among networked computers. Recently two data transmission companies, Aptron and Gammatech, have each developed separate systems that allow network data transmission at rates ten times faster than the current technology allows. Although the systems are similarly priced and are equally easy to use, Aptron's product is likely to dominate the market, because __________.

(A) Gammatech has been in the business of designing data transmission systems for several years more than Aptron has
(B) the number of small businesses that need computer networking systems is likely to double over the next few years
(C) it is much more likely that Gammatech's system will be expandable to meet future needs
(D) unlike many data transmission companies, Aptron and Gammatech develop computers in addition to data transmission systems
(E) it is easier for users of the current data transmission technology to switch to Aptron's product than to Gammatech

Answer: E

Explanation: This is a GMAT critical reasoning assumption-based question. An assumption is an implied hypothesis. So we are looking for something that is implied in the argument. In case it is wrong or maybe disable the argument.

Let’s look at all the available options and choose the one that fits the best.

Pre-thinking: Let us consider that the rivals Aptron and Gammatech are ranked the same on two factors. They could have possibly impacted their demand for price and ease of use. They probably have similar demands. Since this is not the case, there are some other factors that rank Aptron over Gammatech. This fact can be important enough to have an impact on the demand.

Any statement that states that the above-given pre-thinking can be considered correct.

(A) Gammatech has been in the business of designing data transmission systems for several years more than Aptron has
-Option A states that there must be an increase in the appeal of Gammatech over Aptron due to a possible role of loyalty that is coming into the scenario.

(B) the number of small businesses that need computer networking systems is likely to double over the next few years
-Option B implies the increased demand for both rivals without differentiation between the two. Hence this is incorrect.

(C) it is much more likely that Gammatech's system will be expandable to meet future needs
- Option C states that there should be an increase in the appeal of Gammatech over Aptron. This is due to be more pertinent in the future.

(D) unlike many data transmission companies, Aptron and Gammatech develop computers in addition to data transmission systems
-Option D is irrelevant.

(E) it is easier for users of the current data transmission technology to switch to Aptron's product than to Gammatech
-Option E states the differentiating factor that ranks Aptron over Gammatech. Hence option E is correct.
