Focus Question Apollo 13: Mission Highlights

As you reread the first three paragraphs, highlight the names of the two spacecraft in which the astronauts are working and living. Highlight, too, how the text helps readers understand the difference between the two spacecraft. What context clues in paragraph 3, including any Greek or Latin prefixes, suffixes, or roots of words, help readers understand the technical information and technical language in paragraph 2? Highlight specific textual evidence, and use the annotation tool to explain your responses.
