Which is the BEST summary of the passage? After Lowell discovered Pluto, the discovery of Eris led to questions about Pluto’s status as a planet.
Lowell’s dedication to planetary study inspired Americans interest in space.
The Lowell Observatory was a leader in astronomical discovery
Lowel’s study of Mars eventually led to the discovery of Pluto, which was later downgraded to a dwarf planet
The Correct Answer and Explanation is :
The best summary of the passage is: “Lowell’s study of Mars eventually led to the discovery of Pluto, which was later downgraded to a dwarf planet.”
Explanation:
This summary effectively encapsulates the key points made in the passage while remaining concise. Here’s why it stands out as the best option:
- Focus on Major Events: The summary highlights the two major astronomical events related to Lowell: his study of Mars and the subsequent discovery of Pluto. These events are significant in the context of Lowell’s contributions to astronomy.
- Emphasis on Pluto’s Status: It addresses the critical aspect of Pluto’s status change from a planet to a dwarf planet. This transition is pivotal in the narrative about Pluto, especially following the discovery of Eris, which raised questions about what constitutes a planet.
- Exclusion of Extraneous Information: Unlike the other options, this summary avoids additional details about Lowell’s influence on American interest in space or the general contributions of the Lowell Observatory. While these are relevant points, they do not directly contribute to the main storyline focused on Pluto.
- Clarity and Brevity: The summary is clear and succinct, effectively conveying the essential information without unnecessary elaboration. This is crucial in summarization, where clarity helps the reader grasp the core message quickly.
- Chronological Sequence: The summary maintains a logical sequence by linking Lowell’s studies to the outcomes—first studying Mars, then discovering Pluto, and finally addressing its classification as a dwarf planet. This organization helps in understanding the flow of events in the context of Lowell’s contributions.
In summary, the chosen summary provides a clear, coherent, and focused account of Lowell’s work and its implications for Pluto’s status, making it the most effective representation of the original passage’s main ideas.
