Official Solution:
Managing Director: In order to keep the competitive edge gained by our extensive research and innovative methods, information security must remain a high priority for our company. The information stored on our networks including everything from research data, to training materials, to company memos - could be very valuable to competitors. All employees must work to protect company information, not only through passwords, but also through the physical control of company assets, such as laptops.
Which of the following is an assumption necessary for the logic of the argument?
A. The company should install more effective anti-virus software.
B. Company information carries a high monetary value, making the network attractive to individual hackers.
C. The employees will follow the directions of the Managing Director.
D. Competitors may get access to company information if not adequately protected.
E. Other companies which have not taken information security seriously have suffered because of information leakage to competitors.
Premise: “The information ....... could be very valuable to competitors.”
Conclusion: “ ...information security must remain a high priority for our company.”
The assumption is some additional information that would bridge the premise with conclusion.
A. This option could be a suggestion to implement the conclusion and hence is not an assumption to arrive at the conclusion from the premise.
B. This option is a strengthening statement for the suggestion forwarded by the managing director. If, in addition to the competitors, the individual hackers also are interested in the company information, then there is all the more necessity to implement information security in the company. However this statement is not a necessary assumption that bridges premise to conclusion. Even if the hackers are not interested in the company information, the argument would still be valid because the information would still be valuable for the competitors and hence needs to be protected.
C. Whether the employees would follow the Managing Director’s suggestion would determine whether the suggestion would be successfully implemented or not. However the actions of the employees have no role in the argument itself, i.e. they have no role in linking premise to conclusion.
D. CORRECT. This option fills in the gap in the Managing Director’s argument. He states that the information is valuable and then he concludes that the information must be protected. What he has not spoken out is the intermediate assumption, i.e. the competitors may get access to information if not properly protected and that’s why the information must be protected.
In other words if the competitors cannot get access to the information even if unprotected, there is no need to protect the information. Thus option D must be an underlying assumption to complete the argument.
E. Citing an example strengthens the argument but the example is not a mandatory assumption in the Managing Director’s argument. Even if there were no preceding examples, the argument would still hold good and hence this option is not an assumption.
