Millions of illegally reproduced copies are being used. Copies would have generated significant revenue for the company if legally purchased. The company attempts to boost sales. The company has not taken legal measures to prosecute those who have copied the program illegally.
What most helps to explain this paradox?
(A) is irrelevant. It might lead you to think that because it is difficult, the impact on sales is insignificant but since there are millions of illegal copies out there, clearly this answer choice contradicts the premise and has no impact on the conclusion;
(B) is wrong because it provides additional evidence demonstrating that the company could have taken legal action. It adds nothing to explain why the company has not taken such action;
(C) is the correct answer choice. The fact that many people have to try before they buy helps us explain the company's position. The company expects that at least some of these users of illegally reproduced copies would eventually buy the software. It is not a particularly strong argument, and you may think - why not offer a trial version instead? But among all the answer choices, this fact most helps to explain the paradox even though it is far from a perfect explanation.
(D) is irrelevant. So what? The company is looking to boost sales not maximize the number of users of its software;
(E) is wrong as this fact strengthens the view that the company should have taken legal action. The competitor being tough on piracy would only encourage more unauthorized copies of XYZ.
