有人会这到六级题吗?
Space exploration has always been the province of dreamers:The human imagination readily soars where human ingenuity struggles to follow.A Voyage to the Moon—a satirical account of a space voyage,often cited as the first science fiction story—was written by the real Cyrano de Bergerac in 1649,just 40 years after Galileo’s first telescopic observations of the moon.Cyrano was dead and buried for a good three centuries before the first manned rockets started to fly.
In 1961,when President Kennedy declared that the United States would send a man to the moon by the decade’s end,those words,too,had a dreamlike quality.They resonated with optimism and ambition in much the same way as the most famous dream speech of all,delivered by Martin Luther King Jr.two years later.By the end of the decade,both visions had yielded concrete results and transformed American society.And yet in many ways the two dreams ended up at odds with each other.The fight for racial and economic equality is intensely pragmatic and immediate in its impact.The urge to explore space is almost quintessentially the opposite.It is figuratively and literally otherworldly in its aims.
问题；公众public对肯尼迪总统提出的登月计划是什么样的态度
A是it sound like a dream B是 美国人的ambition and spirit

it sound like a dream
再问： 能说一下原因吗？还有They resonated with optimism and ambition in much the same way as the most famous dream speech of all, delivered by Martin Luther King Jr. two years later.中的They指的是谁
再答： 原因：1.n 1961, when President Kennedy declared that the United States would send a man to the moon by the decade’s end, those words, too, had a dreamlike quality.这句话就已经点明了美国民众对这个计划的看法，跟梦一样的质量，也就是说这个计划有点儿异想天开。 2.The fight for racial and economic equality is intensely pragmatic and immediate in its impact. The urge to explore space is almost quintessentially the opposite.这句话表示：为了种族和经济平等的战斗是务实而直接的，而探索太空的冲动是典型的相反的。也就是说探索太空并不务实，不切实际，在做梦。 They应该是指Galileo和Cyrano。
再问： 谢谢你的热情帮助，我有一个小疑虑，这个They有没有可能指的是前面的those words呢？
