Passage Summary: People want old, out-of-print books more now because the Internet makes them much easier to find.

Reasoning: The Internet has made it easier to search for and locate out-of-print books, which has directly caused an increase in the demand for these books.

Analysis: This stimulus establishes a causal link: easier searching leads to higher demand. In a 'Most Strongly Supported' task, we are looking for a reasonable inference that follows from this relationship. You should look for an answer that reflects how the difficulty of finding books acted as a barrier to the market in the past. Avoid any choices that make broad, sweeping claims about all books or the future of the Internet; stay close to the specific relationship between searchability and consumer interest.
