Expression of Ideas practice question

While researching a topic, a student has taken the following notes: - Katherine Johnson (1918–2020) was an American mathematician. - She worked at NASA from 1953 to 1986. - She calculated the trajectory for John Glenn's 1962 orbital flight. - Glenn asked that she check the computer's figures by hand before he flew.

The student wants to emphasise Johnson's importance to the 1962 flight. Which choice most effectively uses relevant information from the notes to accomplish this goal?

  1. A. Mathematician Katherine Johnson calculated the trajectory for John Glenn's 1962 orbital flight, and Glenn asked that she check the computer's figures by hand before he would fly.Correct
  2. B. Katherine Johnson lived from 1918 to 2020.
  3. C. Johnson worked at NASA for over thirty years.
  4. D. John Glenn flew in 1962.

Answer: A. Mathematician Katherine Johnson calculated the trajectory for John Glenn's 1962 orbital flight, and Glenn asked that she check the computer's figures by hand before he would fly.

The calculation and the astronaut's trust in her: her importance to that flight.

Why the other answers are wrong

B. Katherine Johnson lived from 1918 to 2020.
Dates only.
C. Johnson worked at NASA for over thirty years.
Her career length, not the flight.
D. John Glenn flew in 1962.
Omits Johnson.
