A recent survey of people all over the world ranking the happiest countries

provided some surprisingly cold, hard facts. A quick perusal of the happiest ten countries
reveals that several of them, including Switzerland, Iceland, and Finland, have relatively
cold climates. Could it be that the clichéd image of people frolicking in the snow is
actually a guide to living a happy life? The survey certainly proves that people who want
to maximize their happiness should not make their homes in balmy areas.

What is true of the argument made in the last sentence of the passage?
It interprets the data from the survey in a way that clearly supports the personal bias of the passage's author.
It summarizes the findings of a complex survey, giving readers its only logical conclusion in simple words.
It likely draws a faulty conclusion because it is based upon only one factor that several of the countries have in common.
