Question

from ,begin bold,Yellowstone National Park: Geology,end bold,



paragraph 1,The landscape of the Greater Yellowstone Ecosystem is the result of various geological processes over the last 150 million years. Here, Earth's crust has been compressed, pulled apart, glaciated, eroded, and subjected to volcanism. All of this geologic activity formed the mountains, canyons, and plateaus that define the natural wonder that is Yellowstone National Park.

paragraph 2,While these mountains and canyons may appear to change very little during our lifetime, they are still highly dynamic and variable. Some of Earth's most active volcanic, hydrothermal (water + heat), and earthquake systems make this national park a priceless treasure. In fact, Yellowstone was established as the world's first national park primarily because of its extraordinary geysers, hot springs, mudpots and steam vents, as well as other wonders such as the Grand Canyon of the Yellowstone River.



(from "Yellowstone National Park: Geology" by National Park Service)
Which detail from the passage ,begin emphasis,best,end emphasis, supports the correct answer from Part A?

Question 2 Answer options with 4 options
1.
"processes over the last 150 million years" (Paragraph 1)

2.
"define the natural wonder" (Paragraph 1)

3.
"active volcanic, hydrothermal (water + heat), and earthquake systems" (Paragraph 2)

4.
"extraordinary geysers, hot springs, mudpots and steam vents" (Paragraph 2)

Answer 1

Answer: 3

Why: That detail explicitly states Yellowstone contains "active volcanic, hydrothermal (water + heat), and earthquake systems," which directly supports the idea that the park is geologically dynamic. If your Part A was about a different claim, tell me what it was and I’ll re-evaluate.
