While researching a topic, a student has taken the
following notes:
• NASA uses rovers, large remote vehicles with
wheels, to explore the surface of Mars.
• NASA’s rovers can’t explore regions inaccessible
to wheeled vehicles.
• Rovers are also heavy, making them difficult to
land on the planet’s surface.
• Microprobes, robotic probes that weigh as little as
50 milligrams, could be deployed virtually
anywhere on the surface of Mars.
• Microprobes have been proposed as an alternative
to rovers.
The student wants to explain an advantage of
microprobes. Which choice most effectively uses
relevant information from the notes to accomplish
this goal?
A) Despite being heavy, NASA’s rovers can land
successfully on the surface of Mars.
B) Microprobes, which weigh as little as
50 milligrams, could explore areas of Mars that
are inaccessible to NASA’s heavy, wheeled
rovers.
C) NASA currently uses its rovers on Mars, but
microprobes have been proposed as an
alternative.
D) Though they are different sizes, both
microprobes and rovers can be used to explore
the surface of Mars.
