Read the conclusion below.

"Johnson's mathematical ability was highly valued by astronauts on NASA's early space missions."

Which sentence from the article provides the BEST support to the statement above?

• Katherine Johnson was a mathematician who calculated rocket trajectories, or flight paths, and Earth orbits for NASA's early space missions.

• Johnson was one of the "computers" who solved equations by hand during NASA's early years.

• Her work at NASA's Langley Research Center eventually shifted to Project Mercury, the nation's first human space program.

• "Get the girl to check the numbers," a computer-skeptical Glenn had insisted in the days before the launch.

Which answer choice accurately characterizes the reaction of Margot Lee Shetterly to how Katherine Johnson manually confirmed the calculations of a new IBM computer?

• Shetterly was perplexed about why Johnson took so much time to manually confirm the calculations of a computer.

• Shetterly thought it was ridiculous that Johnson was expected to manually confirm the calculations of a computer.

• Shetterly was amazed at what Johnson had to do to manually confirm the calculations of a computer.

• Shetterly appreciated that Johnson was able to quickly perform the task of manually confirming the calculations of a computer.

Read the following selection.

"Our office computed all the (rocket) trajectories," Johnson told The Virginian-Pilot newspaper in 2012. "You tell me when and where you want it to come down, and I will tell you where and when and how to launch it."

WHY did the author include this selection?

• to suggest that Johnson had more responsibility than other people who worked at NASA

• to indicate that Johnson enjoyed talking about the work she did at NASA

• to suggest that Johnson felt burdened by the responsibility she had at NASA
