While researching a topic, a student has taken the following notes:
<ul> <li>The Tunguska event occurred in Siberia in 1908.</li> <li>It flattened roughly 2,000 km^2 of forest.</li> <li>No impact crater was ever found.</li> <li>Most researchers attribute the event to an asteroid or comet exploding in Earth's atmosphere.</li> <li>The energy released was estimated at 10-15 megatons of TNT.</li> </ul> The student wants to introduce a counterintuitive aspect of the Tunguska event. Which choice most effectively uses relevant information from the notes to accomplish this goal?Which choice most effectively makes the student's point?
- Acheck_circle
Although the 1908 Tunguska event flattened 2,000 km^2 of Siberian forest, no impact crater was ever found, suggesting the object exploded in midair.
- B
The Tunguska event released energy estimated at 10-15 megatons of TNT.
- C
The Tunguska event occurred in Siberia in 1908.
- D
The Tunguska event flattened forest in Siberia.
Explanation
The counterintuitive aspect is the lack of crater despite the immense damage. Choice C juxtaposes destruction with no crater, then explains the leading interpretation. The others miss the tension.
