本题讨论对立观点对进步的意义的问题，题目认为进步好的方式是和持有对立观点的人们讨论。题目改编自老GRE的ISSUE209 "Progress is best made through discussion among people who have contrasting points of view" 类似的题目有老GRE的ISSUE122 "We owe almost all our knowledge not to people who have agreed, but to people who have disagreed"，和ISSUE1 "We can usually learn much more from people whose views we share than from people whose views contradict our own; disagreement can cause stress and inhibit learning"。在分析的过程中，可以从讨论过程中产生的正负面意义和直接间接效果、进步需要的条件、不同领域的不同情况等方面展开思考。需要注意的是题目在讨论“最佳方式”的问题，可以给出其他方式，但不能无视题目限定的范围（和对立观点以及讨论相关）而岔开话题自说自话。
