Despite the anti-virus protection program installed on its computers, SmartTech has received many complaints from consumers that their computers had become infected with viruses. In order to reduce the number of its computers vulnerable to viruses, the CEO of SmartTech Corp. has had the company's engineers install three different virus-blocking programs on each computer before shipping them to consumers. Nevertheless, customer reports of computer viruses have risen since the institution of this initiative.

Which of the following, if true, most helps to explain why acting on the CEO's plan failed to achieve her goal?


A. The installation of the three anti-virus programs has led to increased labor costs, taking away resources from other company departments.

B. When more than one anti-virus program is installed on a machine, the programs can become less effective.

C. Many consumers have found that it is more difficult to use a computer with three anti-virus programs than with one.

D. Corporations that are already vulnerable to hackers often use SmartTech's computers but have stopped doing so since the increased viruses.

E. SmartTech has lost approximately 25 percent of its clients as a result of its computers' vulnerability to viruses, though it regained a third of these with its recovery efforts.

Prethinking : One anti-virus program was already installed on computers. Installing more anti-virus programs may have a negative effect on each other by one blocking the other two etc

A. The installation of the three anti-virus programs has led to increased labor costs, taking away resources from other company departments.

The CEO's plan failed because of increase in number of complaints has risen and not because of costs. INCORRECT

B. When more than one anti-virus program is installed on a machine, the programs can become less effective.

This option aligns with prethinking saying antivirus program doesn't work together well.

C. Many consumers have found that it is more difficult to use a computer with three anti-virus programs than with one.

The number of antivirus complaints has risen and not the complexity of using the computers. INCORRECT

D. Corporations that are already vulnerable to hackers often use SmartTech's computers but have stopped doing so since the increased viruses.

Same explanation as option A. The CEO's plan failed because of increase in number of complaints has risen and not because of loss of customers.. INCORRECT

E. SmartTech has lost approximately 25 percent of its clients as a result of its computers' vulnerability to viruses, though it regained a third of these with its recovery efforts.

This statement supports the CEO's plan and doesn't explain why the number of antivirus complaints went up. INCORRECT

Hence option B

Official Explanation


Answer = (B). If one is good, are three necessarily better? Not if the three interact to hinder one another! In this scenario, computers with three anti-virus programs are getting more viruses than computers with just one virus. There could be many explanations for this: maybe one anti-virus program views another as a virus and disables it; maybe their activation is impossible when other programs are detected. In any case, the addition of these programs seems to have increased the machines’ vulnerability to viruses; (B) explains this situation well.

While this initiative might have cost the company more (and probably did), (A), this isn’t a reason that three programs would be less effective than just one.

(C), even if it is true, is not relevant. Consumer use of the product is not linked, at least in this passage, to the acquisition of computer viruses, nor is their difficulty using the computers linked to the machine’s vulnerability.

If vulnerable corporations stopped using the machines (D), it would make sense for fewer, not more, viruses to infect these computers, as some of the most open targets would have been removed from the field.

Finally, SmartTech’s customer retention rate (E) doesn’t have anything to do with how vulnerable, or invulnerable, its computers are to viruses.
