Passage Summary: A video game company is losing sales to pirates, so they are adding a new security feature and expect that people will start buying the games instead of stealing them.

Conclusion: Ditalgame will see a significant rise in game sales after implementing new copy protection.

Reasoning: The company's games are currently being illegally copied on a large scale, and the new feature is designed to stop this piracy.

Analysis: The president's prediction relies on a key assumption: that people who are currently pirating the games will actually pay for them once the 'free' option is removed. To strengthen this, look for an answer that suggests these pirates have the desire and means to buy the games. Alternatively, an answer could show that the new security feature won't annoy legitimate customers so much that they stop buying the games themselves.
