Read the passage and answer the questions. Can humans migrate to Mars?
As early as more than a century ago in science fiction, humans began to walk on Mars, but until today, it was still just a hypothesis. However, many people believed that the question was not whether humans could land on Mars, but when and how to get there. To this day, no one knew exactly how to get to Mars in the most convenient and effortless way. Some people estimated that a human landing on Mars would require 60 billion US dollars, or even more. However, the president of the Mars Society, Robert Zublin, believed that this figure should be 30 billion to 40 billion US dollars, which was equivalent to the cost of the Apollo Moon landing program. Zublin published a book called "Immigrating to Mars," which outlined the grand blueprint for human settlement on Mars. Why did humans always yearn for Mars? Based on the current observations, Mars was the most likely place to become a second home for humans. Even though the temperature on Mars was-200 ° C, the environment on Mars was the most similar to Earth's. Mars 'diameter was about half of Earth's, and it had a third of Earth's gravity and a hundredth of Earth's atmospheric concentration. Most importantly, the probe had discovered the presence of water at the frozen poles and below the surface of Mars. Every two years, Mars would approach Earth once. Last summer, Mars came to a distance of 55.76 million kilometers from Earth. This was the closest it had been to Earth in 60,000 years. Zublin said,"People really want to know if there is life outside of Earth. Mars may be the key to solving this problem. On Mars, even if we can only find primordial microorganisms, it means that human-like life doesn't only exist on Earth." The president of the Planetary Society, Louis Frederman, said that the basic question humans wanted to answer was, where did humans come from? Where were they going? "What is most attractive to us about Mars is that it is likely to help us understand the origin and destination of life." "Moreover, Mars is the only place we know that humans have the opportunity to migrate. Humans will use this to prove that they will not stay on Earth forever. If we (A) can migrate to Mars, then Earth may (B) be our only home. We will have to re-examine the relationship between humans and Earth." 1. The following sentence is inconsistent with the passage. (1) Humans taking a walk on Mars was still just an idea. (2) People firmly believe that humans cannot go to Mars. (3) Zublin's book,"Immigrating to Mars," outlines the grand blueprint for human settlement on Mars. (4) No one knows the most convenient and energy-saving way to reach Mars. 2. Read the second paragraph and point out the four conditions that are most likely to make Mars a second home for humans.①___________________________________________________________②___________________________________________________________③___________________________________________________________ A brief answer.

Answer 1

Humans could not move to Mars yet. However, many people still believed that this situation would change with the development of science and technology.

As early as more than a century ago, the science fiction novel "The Hitchhiker's Guide to the Galaxy" described the scene of humans building a huge spaceship to go to Mars and establish a colony there. However, due to the technical limitations at the time, this idea was ultimately proven to be unfeasible.

Currently, humans could send people and supplies to Mars through spacecraft, but long-term settlement on Mars was still a challenge. Mars 'atmospheric pressure was very low, and the temperature was extremely low. The lack of an atmosphere and liquid water was a huge obstacle to human survival.

However, as technology continues to develop, we may find better ways to solve these challenges. For example, we can try to build more advanced spacecraft and life support systems or explore other planets suitable for human habitation. In the future, we may see more exploration and adventures, as well as more likely human colonization of Mars.
