2. According to the article, Perseverance will lay the groundwork for future trips to Mars.
Which paragraph BEST supports this idea?
(A)
On February 18, 2021, NASA's new rover, Perseverance, arrived on Mars, a neighboring planet in our
solar system. During a seven-month journey, it traveled 470 million kilometers (300 million miles) to
reach Mars. The exploration robot landed in a region called the Jezero Crater. Near the planet's equator,
the crater is 45 kilometers wide (28 miles)
(B)
Perseverance is about the size of a car, has six wheels and, like all rovers, moves on its own. It has two
computers, which it uses to navigate: one computer figures out where the rover needs to go and the
other computer "sees its surroundings.

(D)
The first two NASA spacecraft to land on Mars were Viking 1 and 2 in 1976. Later, scientists began
using moving robotic vehicles called rovers to explore the planet. Perseverance is the fifth rover to land
on Mars, joining four other six-wheeled bots named Sojourner, Spirit, Opportunity and Curiosity
So far, exploring planets such as Mars has only been done using robots. But this could change during
your lifetime, as space agencies like NASA and private companies are working to make human
missions to Mars a reality. The hope is that the Perseverance mission, along with others, will help
achieve goal
