Problem Statement

Julie's school wanted to determine how speaking languages affected people's intelligence.

They made all the most fluent speakers take an IQ test. This is what they found:

1) The students most fluent in Spanish were smarter than the students most fluent in Italian.

2) All the Italian speakers were smarter than all of the Latin speakers.

3) All the Latin speakers were smarter than most of those who spoke Spanish.

Which of these sentences can be concluded from the above information?

Spanish Speakers had the highest range of intelligence.

People who spoke Latin were generally good at speaking Spanish.

On average, the smartest people could speak Spanish.

To be intelligent, it is better for a student to be able to speak Italian and Latin over Spanish.
