Answers

Both "Do high pressure systems prefer forming in Ecuador compared to in Springdale?" and "Are average yearly temperatures in Ecuador greater than in Springdale?" are acceptable questions. The others deal with subjectivity.

Final answer:

The only testable question from the options provided would be asking if the average yearly temperatures in Ecuador are greater than those in Springdale. This question allows for a factual comparison using data.

Explanation:

When comparing climates, we must focus on quantitative, measurable aspects. So, the testable question here most appropriate for Sam's inquiry would be: Are average yearly temperatures in Ecuador greater than in Springdale?. This question relies on measurable, empirical data related to the large scale weather patterns of two distinct geographic locations. It will allow a factual analysis of the differences in climate between Springdale and Ecuador, specifically in terms of average yearly temperatures.
