Read the following statement.
Scientists have a great interest in learning more about Mars.
Which sentence from the passage best supports the statement?
Mars
Compared to other planets in the Solar System, Mars is the most like Earth. Mars has 24-hour days and can go through seasonal and weather changes. The conditions on the planet are also not too harsh. Because Mars is almost like Earth, scientists believe that the planet could have supported life.
Scientists have sent many missions to Mars to gather information. On these missions, scientists sent robots out to space. Some of the robots took pictures of Mars or orbited the planet. Other robots landed on Mars to explore the planet's surface. The information that the robots sent back to the scientists was valuable. One day, scientists hope to send humans to Mars to explore it further.
