What is a common consequence of a low-pressure system?

The presence of a low-pressure system is commonly associated with clouds and precipitation. Low-pressure areas lead to rising air, which cools and condenses as it ascends, forming clouds. This process often results in various forms of precipitation, such as rain, snow, or storms, depending on other atmospheric conditions.

In contrast, a high-pressure system typically brings clear skies and stable weather due to descending air that inhibits cloud formation, which clarifies why the first choice does not align with the characteristics of low-pressure systems. Increased wind speeds and stable weather are generally associated with high-pressure systems as well, rather than low-pressure systems where winds can become turbulent and variable due to the rising air. High humidity and cold conditions may occur in some low-pressure systems, but it is the cloud formation and precipitation that are more definitive characteristics, making this option the most accurate representation of the consequences of low-pressure systems.
