Final answer:
Performance requirements for maneuvers are based on factors like communication skills, accuracy, safety, and not on subjective attributes like vehicle color or personal attitude. Communication skills play a significant role in technical professions such as engineering.
Step-by-step explanation:
The performance requirements for specific maneuvers do not involve vehicle color and cleanliness (A) or attitude and personality (B) as grading factors. Instead, they are more aligned with communication skills and body language (C), as well as accuracy, speed, and safety (D). In various professional fields such as engineering, possessing strong technical abilities are crucial.
However, good communication skills are also essential and often required, as suggested by various job advertisements. When evaluating performance, assessors typically consider both technical proficiencies, such as physical awareness, stamina, expressive freedom, flexibility, relaxation, and open readiness, and the ability to effectively communicate.
This balance between technical skills and communication ability ensures well-rounded competence in professional settings.
