Accepted Answer

# Brief Explanations:
1.
  - a. "Exploring space benefits everyone on Earth" is an opinion as it is a subjective view about the impact of space - exploration.
  - b. "The United States was first to land a man on the moon" is a fact as it is a verifiable historical event.
  - c. "The United States and Russia are working together to build the International Space Station" is a fact as it is a current - day verifiable activity.
  - d. "Countries should work together instead of in competition" is an opinion as it expresses a value - based preference.
2.
  - a. The Soviet Union had several early space "firsts" such as the first satellite (Sputnik 1) and the first human in space (Yuri Gagarin), but it is not clear - cut that they had more "firsts" than the United States overall. However, historically, they did have significant early achievements, so this statement could be considered true depending on the scope of "firsts" considered.
  - b. The space - race competition between the United States and the Soviet Union did not end when the United States landed a man on the moon. There were still many subsequent space activities and rivalries, so this statement is false.
3. It is important for people to be able to live in space for long periods of time for several reasons. It allows for in - depth scientific research such as studying the long - term effects of microgravity on the human body, conducting experiments that require extended observation, and exploring the potential for space colonization. It also helps in the development of technologies for future long - distance space travel, like missions to Mars.
