Which passage from the Article best shows why the Mars Desert Research Station was probably built where it was?A.This crew is preparing for what it might be like to live on Mars. They're at the Mars Desert Research Station (MDRS). This barren place looks a whole lot like the Red Planet. But don't let the reddish soil and huge rocks fool you. It's the U.S. state of Utah!B.The first human city on Mars may seem light-years away. But thanks to the forward-thinking folks at MDRS, life on Mars just might be closer than we think. For now, though, Utah will have to do.C.Each crew of volunteers stays at the MDRS for two or three weeks. While there, they really do live like astronauts on Mars. They bunk in the "Hab." It has a kitchen, bedrooms, and a living space perfect for earthlings.D.Sound like fun? Maybe so! But this isn't just some space-themed sleepaway camp. The MDRS is owned and run by the Mars Society. The group believes that humans will someday settle on Mars. And they're not alone.

Which of these is an opinion?HINTA.The reddish land in the U.S. state of Utah looks a lot like Mars.B.MDRS crews are wasting their time because Mars is different from Earth.C.One group of volunteers at the MDRS collected soil to grow crops in.D.NASA thinks that humans will someday live on the Red Planet.

The Article says:Many of these volunteers are scientists and engineers. Others are college students. Together, they carry out research that might help future Mars missions. For example, one crew collected soil to study how to grow crops on Mars.The author uses this passage mostly to __________.A.question the usefulness of the work carried out at the MDRSB.point out that most of the scientists like the work they do at the MDRSC.show how difficult the MDRS research can be for the volunteersD.give the reason why crew members stay and do work at the MDRS

"The images of Mars taken by the Mariner 9 probe indicate the presence of valleys that looks like the stream beds on Earth. The images also show that Mars once had an atmosphere that was thick enough to trap Sun's heat. If this is true, something must have happened to Mars billions of years ago that stripped away its atmosphere."This paragraph supports which of the following statements:-Mars has little or no atmosphere.Mars once had an atmosphere thicker than Earth's atmosphere.Mariner 9 probe took the first picture of Mars.Mars is closer to Sun than Earth.

The reader can tell from the Article that __________.A.the people who work at the MDRS must be either scientists or engineersB.NASA chose some MDRS volunteers to take part in a real trip to MarsC.astronauts living on Mars might use the Martian soil to grow crops inD.the two rovers at the MDRS are just models and do not really workSUBMITExtras© 2024 Achieve3000 Inc. and its licensors.All Rights Reserved.
