Question

6 based on the selection, what is the most important reason for astronauts to exercise while in space? to prevent sinus congestion to prevent strain on the heart to prevent backaches to prevent muscle and bone loss 8 how is skydiving similar to space travel? both involve a \free fall.\ both involve forward motion. both can cause loss of calcium. both can cause sinus congestion. 7 what conclusion is supported by information from the selection? fear of weightlessness keeps many people from becoming astronauts. some astronauts never recover from the effects of weightlessness. weightlessness causes a wide range of physical symptoms. studying the effects of weightlessness is extremely expensive. 8 what is a reasonable question to ask about the effects of weightlessness on humans after reading this selection? how long does it take astronauts to recover from weightlessness? who will be the next astronaut to experience weightlessness? how much scientific training is required to become an astronaut? when is the best time of day to launch a space shuttle from earth?

Explanation:

Since the text is a bit unclear (some words are smudged), but assuming we are answering question 7:

To determine the supported conclusion, we analyze each option:

• Option 1: The passage doesn't mention fear of weightlessness preventing people from being astronauts.
• Option 2: There's no info about astronauts never recovering from weightlessness effects.
• Option 3: Weightlessness is known to cause physical symptoms like sinus congestion, backaches, etc. (implied by related questions), so this is supported.
• Option 4: The passage doesn't discuss the cost of studying weightlessness effects.

A reasonable question about weightlessness effects should relate to its impact on humans.

• Option 1: Asking about recovery time from weightlessness is relevant to its effects.
• Option 2: Next astronaut to experience is not about effects.
• Option 3: Scientific training for astronauts is not about weightlessness effects.
• Option 4: Launch time is not about weightlessness effects.

Answer:

C. Weightlessness causes a wide range of physical symptoms. (Assuming the third option is labeled C; adjust label based on actual question numbering)

For question 8:
