SAT Question 3dcc7140: Answer & Explanation

While researching a topic, a student has taken the following notes:

• Nissologists are scientists who study islands.
• Some nissologists define an island as any piece of land surrounded by water.
• Using that definition, they determined that Sweden has 221,000 islands.
• Other nissologists define an island as being 1 kilometer square, a certain distance from the mainland, and having at least 50 permanent residents.
• Using that definition, they determined that Sweden has 24 islands.

Difficulty:Hard

The student wants to make and support a generalization about nissologists’ definition of an island. Which choice most effectively uses relevant information from the notes to accomplish these goals?

The definition of an island as any piece of land surrounded by water is supported by some nissologists, scientists who study islands.

Multiple counts of Sweden’s islands have been based on different definitions of an island.

Based on a recent count, Sweden has a relatively small number of islands with at least 50 permanent residents.

Nissologists’ different definitions can result in huge disparities in counts of islands, as the example of Sweden shows.
