The correct answer is C) a dry climate with little rainfall.
The Jones family lives on the western side of the Sierra Nevada Mountains, and they experience a wet climate much of the year. The Greer family lives on the eastern side of the mountain range. The type of climate that the Greers most likely experience is a dry climate with little rainfall.
What happens in the Eastern side of the Sierra Nevada mountains is that it gets dry airmass, in opposition to the humidity conditions of the westside. So the climate is weird in this mountain range that covers a big portion of California. The prevailing winds of the west side of the mountains contain warm moist air that condenses and causes rain, meanwhile the East side only gets dry air, in what meteorologists call the "Rain Shadow Effect."
