Answer:
A. something seemingly impossible can become a reality
Step-by-step explanation:
The author of the text starts with the story about how President Kennedy had a dream for the US to explore space and land a man on the moon. He says that, at the time, this goal was thought to be impossible and compared to science fiction – meaning it could only be imagined in the fantasy narrative.
Yet, the impossible became the reality when Apollo 11 landed on the surface of the moon in 1969. The author tells this to explain to us how things that one day might seem unachievable and fantasy can become reality, and prove us with the real historical evidence.
