• "...is worn like a backpack." (paragraph 8)

• "...fly back to the spacecraft." (paragraph 8)

• "...with a small joystick..." (paragraph 8)

8 Part A How does the first picture in the passage support the idea that spacewalks can be dangerous for astronauts?

• by showing how thin and light the spacesuits are

• by showing an astronaut doing work in space

• by showing how an astronaut is connected to a spacecraft

• by showing a tool used on a spacewalk

8 Part B Which detail from the passage best supports the answer to Part A?

• "They can repair satellites or spacecraft that are in space." (paragraph 2)

• "Once in their suits, astronauts breathe pure oxygen for a few hours." (paragraph 5)

• "These gas bubbles can cause astronauts to feel pain in their shoulders, elbows, wrists, and knees." (paragraph 5)

• "The safety tethers keep astronauts from floating away into space." (paragraph 7)

9 Part A What is the connection between paragraphs 4 and 5 of the passage?

• Paragraphs 4 and 5 compare the air in a spacesuit to the air in the spacecraft.

• Paragraphs 4 and 5 show the sequence of steps astronauts take to prepare for a spacewalk.

• Paragraphs 4 and 5 show the solution to the problem of having gas bubbles in the blood described in paragraph 5.

• Paragraph 4 shows the effects of staying in a spacesuit too long and paragraph 5 shows the causes.

9 Part B Choose one detail from paragraph 4 and one detail from paragraph 5 that best support the answer to Part A.

• "This pain, is called getting 'the beds' because it affects the places where the body bends." (paragraph 5)

• "When on a spacewalk, astronauts use safety tethers to stay close to their spacecraft." (paragraph 7)

• Astronauts fly through space to explore during spacewalks.

• Astronauts hook tools onto their spacecraft during spacewalks.

• Astronauts can make repairs to objects during spacewalks.

• Astronauts do scientific tests on their bodies during spacewalks.

10 Part B Which detail from the passage supports the answer to Part A?
