Choose the statements that can be inferred from the passage.

There are plants growing on Mars.
The greatest to life on Earth used to be nuclear missiles.
One day, humans will have to go and live on another planet.
Our Plan A includes developing renewable energy resources.
The Biosphere 2 experiment ended in failure.
Since the 1960s, we have been sending unmanned spacecraft to Mars... space agencies of various countries are planning manned missions to Mars that could take place within the next 25 years.(Para3)
In the 1960s and 1970s, the greatest fear was that the human race, and possibly all advanced life forms on the planet, could be wiped out by nuclear missiles.(Para1)
Scientists are thinking of ways to lower this risk, such as replacing coal and oil with forms of renewable energy.(Para1)
Although the two-year experiment was not a success, it did provide us with a better understanding of how humans might be able to live on another planet.(Para4)
Sometimes, we need to form opinions and draw conclusions that are not directly stated within the given information. For example, from the sentence “While the Moon can be reached within days, it would take months to reach Mars, travelling through dangerous solar radiation”, we can infer that the Moon is less exposed to dangerous radiation than Mars. Headings and pictures can also help us make educated guesses about a text.
