Which passage is noted for providing insufficient reasons to support its claim?

The identification of Passage 1 as the one providing insufficient reasons to support its claim suggests that it lacks strong evidence, logical reasoning, or adequate support for the argument presented. This often means that the claims made in Passage 1 might be based on assumptions or insufficient information, failing to persuade the reader effectively.

A well-supported passage typically includes concrete examples, statistics, logical reasoning, or authoritative references, which help to substantiate its claims. By contrast, when a passage does not include these elements, it leaves the reader unconvinced, as it does not allow for a thorough understanding of the argument's validity.

In the context of the other options, if Passage 2 was noted for providing sufficient reasons, it would have a compelling basis that supports its claims. Similarly, choosing 'Neither passage' or 'Both passages' would suggest that either both lacked support or that neither did, which contradicts the assertion that Passage 1 stands out for its insufficiency. Thus, the selection of Passage 1 underscores the importance of adequate reasoning in making effective arguments.
