Question

read the passage.
whats beneath your plane?
as shane loeffler, a geology student at the university of minnesota, was flying home from europe, he looked down at the landscape and began to wonder what he was flying over. he realized that a plane flight would be a good opportunity for people to learn about the geological features of the earth below them. as a result of this experience, with a grant from the national science foundation, he created a free app called flyover country. the app provides users with information on natural formations, man - made features like dams, and even where fossils can be found. the features are pinpointed on a map that corresponds to the landscape below the plane.
what is the main, or central, idea of the passage?
shane loefflers plane flight home from europe led him to think about the geological features of the land below him.
shane loefflers experience in a plane led him to create an app that would provide information to flyers about the land below them.

Explanation:

To find the main idea, we analyze the passage. The first part tells about Shane's flight and his wonder about the landscape. But the key action is his creation of the Flyover Country app (with a grant) that provides info on geological and man - made features below the plane. The first option only focuses on his thinking, while the second option covers the cause (his plane experience) and the result (creating the app to inform flyers about the land below).

Answer:

Shane Loeffler's experience in a plane led him to create an app that would provide information to flyers about the land below them.
