关于写作中间立场的讨论

Need NIUs to shed some light on this. When I review the AI topics, sometime I find myself compelled to argue in a mixed stand. For example: 21、“job security and salary should be based on employee performance, not on years of service. rewarding employees primarily for years of service discourages people from maintaining consistently high levels of productivity.” I tend to claim that employee should be rewarded/evaluated base on both performance as well as loyalth and seniority in the company. The point goes against author's "not on years of service". However, the point is also not aligned with "rewarding employees primarily for years of service". Hence it falls into a middle ground. Should we avoid arguing from such a gray area in a 30min writing test? What if I find it too extreme to stand on either side of the spetrum? 谢了，
