Read the following segment from a paper Ali wrote: The Yellowstone volcano is one of the largest volcanoes in the world, and it’s located next to Grand Teton National Park. “Sometimes [Yellowstone] erupts with lava flow, but once or twice every million years, it erupts very violently,” says Ilya Bindeman, professor of geological sciences at the University of Oregon. Unlike Yellowstone, there are no volcanoes in the Grand Tetons. The Grand Tetons are mountains that resulted from uplift along a tectonic fault line, and, according to the Wyoming State Geological Survey, are among the youngest mountains in the Rockies.

What was likely missing from Ali’s research process? Why?

A.
Credible sources; because Bindeman does not appear reliable.
B.
A narrow topic; because the paragraph talks about two different topics.
C.
Multiple avenues of exploration; because the paragraph contains few facts, indicating little research.
D.
Further research questions related to her initial findings; because the paragraph could use more information on volcanoes from other areas.
