1. What is the biggest issue with sending astronauts to Mars?
they could be too old to work after making the long journey
they could get sick from living together
their bodies could be injured during the landing
their health could be affected by spending a long time in space
2. What is one thing that Scott and Mark Kelly have in common?
they both will set a single-mission record
they both want to take a future trip to Mars
they both have been to space in the past
they both will perform experiments in space
3. Why are Mark and Scott Kelly perfect for NASA's study?
one twin has been on more missions than the other, so comparing them will help NASA determine the effects of space on the body
they have both been to space, so they have experienced identical physical changes to their bodies in the past
they are biologically identical and are the same age, so differences in their body during the next year will likely be caused by space
one twin has retired, so his body will likely show different physical changes than the twin who is still going to space
4. What do the details in the article suggest most clearly about life on the International Space Station?

it is lonely because there is often no one to talk to
there is a high level of danger and stress

conducting an experiment to see if an idea is correct
6. What is the meaning of the Latin root dur?
7. In the article which detail best supports the inference that the trip to the International Space Station is risky?
Scott's brother is not joining him on the trip
The phone connection from the space station can be unpredictable
Scott will spend his days doing science experiments
People's bones get brittle and their sense of balance changes in space
8. Which sentence best states the central idea of the article?
Mark and Scott Kelly have had many adventures in space during their lives.
NASA hopes to learn from Mark and Scott how long-term space travel affects health
NASA wonders whether going into space could have an effect on the human body.
Scott will spend a year on the International Space Station with various other astronauts
9. Which inference can you make based on the key details from the article?
Russian cosmonauts have spent more time in space than American astronauts have
Other astronauts have a brother or sister who has also gone to space
Some astronauts who spend six months in space experience no physical changes
No American astronaut has ever been in space for a year
10. Based on information from the article, what is the goal of NASA's experiment?
to separate the effects of aging from the effects of space
to determine why some people are better suited for space than others
to learn whether people with genetic illnesses can survive in space
to identify strategies that prevent astronauts' bodies from being damaged
11. who will join Scott on the International Space Station? Choose two options.
his twin brother, Mark Kelly
NASA doctors and psychologists

a rotating group of crew members
Russian cosmonaut Mikhail Kornienko
12. What is the meaning of program manager?
someone who writes code for computer software
someone who fixes machinery or other equipment
someone who is in charge of one or more projects
someone who funds research and experimentation
What is the main question NASA wants to answer through this mission?
Are twins able to survive in space?
Do space affect living things?
Do human body change in space?
What are the long term effects of space on human body?
