With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: In swing dances, tension and compression may be maintained for a significant period of time. In other dances, such as Latin, tension and compression may be used as indications of upcoming movement. However, in both styles, tension and compression do not signal immediate movement: the follow must be careful not to move prior to actual movement by the lead. Until then, the dancers must match pressures without moving their hands or legs. In some styles of Lindy Hop, the tension may become quite high without initiating movement.
text_B: Does someone have good form if they only move their legs while trying to match pressure?
NO.
