1. refer to your expeditions in reading book for a complete version of this text.

read the following summary of “mathematician katherine johnson at work.”

katherine johnson joined naca in 1953 as part of a team of african american women who were trained as mathematical researchers. from the beginning, katherine stood out as a strong leader who was eager to learn. she was also an expert at math calculations and was moved from the research team to work with engineers on flight projects. when the u. s. decided to invest in space exploration, naca became nasa and katherine was an important part of the program’s success. she worked on several early space missions, including the first flight to the moon. later, she contributed to projects like the space shuttle program.

which key detail should be included to complete the most effective summary?

a. katherine worked for nasa for more than thirty years and, in 2015, she received the presidential medal of freedom in honor of her service and contributions.

b. after 1962, katherine spent time with young people them find careers in science or technology.

c. katherine made sure that computer calculations were correct and solved many problems by approaching them differently from the engineers she worked with.

d. katherine contributed more to the u. s. space program than any other individual who worked for nasa.

2. read the following paragraph from “katherine johnson biography.”

in 1962, as nasa prepared for the orbital mission of john glenn, katherine johnson was called upon to do the work that she would become most known for. the complexity of the orbital flight had required the construction of a worldwide communications network, linking tracking stations around the world to ibm computers in washington, dc, cape canaveral, and bermuda. the computers had been programmed with the orbital equations that would control the trajectory of the capsule in glenn’s friendship 7 mission, from blast off to splashdown, but the astronauts were wary of putting their lives in the care of the electronic calculating machines, which were prone to hiccups and blackouts. as a part of the preflight checklist, glenn asked engineers to “get the girl”—katherine johnson—to run the same numbers through the same equations that had been programmed into the computer, but by hand, on her desktop mechanical calculating machine. “if she says they’re good,’” katherine johnson remembers the astronaut saying, “then i’m ready to go.” glenn’s flight was a success, and marked a turning point in the competition between the united states and the soviet union in space.

question 1
part a

what is the author’s point in this paragraph?

b. astronauts regularly depend on the calculations made by machines.

c. the flight of the friendship 7 mission is made possible by the construction of a worldwide communications network.

d. katherine’s contributions make the friendship 7 mission happen and to establish the united states as leaders in space.
