The two correct answers that can help determine air pressure are:
-
Temperature of the air - As temperature changes, it can affect air pressure; warmer air is generally less dense than cooler air, affecting pressure readings.
-
Moisture in the air - Humidity levels can influence air pressure; moist air is less dense than dry air, which can lead to variations in pressure.
Cloud patterns and wind speed can be affected by air pressure but don't directly help in determining it.
