what was the primary purpose of the inuits invention of snow goggles?
a to protect their eyes from sunlight reflected off the snow.
b to keep their eyes warm in cold weather.
c to improve their night vision.
d to help them see better underwater.

Explanation:

Inuit snow goggles were designed to reduce the intense glare from sunlight reflecting off snow. This glare (also known as snow blindness) can harm the eyes. Options B (keeping eyes warm) is not the main purpose - goggles' design (narrow slits) is more about light reduction. Option C (improving night vision) is incorrect as they were for bright daylight conditions. Option D (seeing underwater) is unrelated to their typical use in snowy, sun - exposed environments.

Answer:

A. To protect their eyes from sunlight reflected off the snow.
