Answer:
B
Explanation:
The barometer is a piece of equipment that can be used to predict weather conditions, and more specifically atmospheric pressure.
A level of 30 inches of mercury is considered to be a normal "height", so therefore, a level in the high 30s, should be considered high.
Another typical reading taken from barometers are how the levels indicate the weather. If the level is decreasing, that tends to mean that the weather is getting worse, and if it gets higher, then the weather should be becoming better. Hence, if the reading is high, then the barometer indicates good weather.
