What skill is likely to improve when cadets practice under pressure during drills?

When cadets practice under pressure during drills, the skill that is most likely to improve is time management. Drills often involve executing tasks within a set timeframe, which requires cadets to prioritize their actions, allocate their time efficiently, and respond quickly to changing scenarios. This environment of pressure can lead to the development of better decision-making skills, as cadets learn to identify what tasks are most important and how to complete them effectively and promptly.

The other options, while important in their own right, do not specifically correlate with the skills honed through high-pressure practice during drills. Socializing is more focused on interpersonal interactions, writing skills pertain to expression and composition of written material, and reading comprehension involves understanding and interpreting text; none of these are directly enhanced through the time-sensitive and action-oriented nature of drill practices.
