We are looking for an assumption that connects evidence and conclusion. First, read the stimulus and identify the argument. How are the evidence and conclusion different from each other? Try to work out the assumption that holds them together.
The advertisement contains an argument built on three pieces of evidence:
- Quicktrak is growing fastest;
- Quicktrak offers the most up-to-date international business news, and the most comprehensive company information needed to make wise investment decisions;
- Quicktrak is the only service devoted exclusively to these two types of news.
Based on this evidence, the advertisement concludes that subscribing to any other financial news service would be a disservice to your company. There are many assumptions here. But the most crucial assumption is that the two types of news Quicktrak provides must be useful to any company. Choice (B) explicitly states the latter assumption and is the correct answer.
