In which month does Buenos Aires experience winter? A) January, because it is located in the Southern Hemisphere. B) January, because it is located in the Western Hemisphere. C) July, because it is located in the Southern Hemisphere. D) July, because it is located in the Western Hemisphere.

What the question is really testing

This is a seasons and hemispheres question. You need to know which hemisphere Buenos Aires is in, then match that to when winter happens in that hemisphere.

Locating Buenos Aires on the globe

Buenos Aires is in Argentina, which lies south of the Equator. That means Buenos Aires is in the Southern Hemisphere.

Matching hemisphere to seasons

In the Southern Hemisphere, seasons are opposite to those in the Northern Hemisphere:

• Southern Hemisphere winter happens roughly in $\text{June to August}$.
• $\text{July}$ is a winter month there.

Why the other choices are wrong

• Choices mentioning the Western Hemisphere confuse location with seasons. Being east or west of the Prime Meridian does not determine seasons.
• January is summer in the Southern Hemisphere, not winter.
