Expression of Ideas practice question

A student took these notes: • Ada Lovelace lived in nineteenth-century England. • She worked with Charles Babbage on his proposed Analytical Engine. • She wrote an algorithm intended to be carried out by the machine. • Many historians consider this the first published computer program.

The student wants to explain why Ada Lovelace is historically significant. Which choice most effectively accomplishes this goal?

  1. A. Ada Lovelace lived in nineteenth-century England and knew Charles Babbage.
  2. B. Charles Babbage proposed a machine called the Analytical Engine.
  3. C. Ada Lovelace wrote an algorithm for Babbage's Analytical Engine that many historians consider the first published computer program.Correct
  4. D. Ada Lovelace lived during the nineteenth century, a period of rapid technological change.

Answer: C. Ada Lovelace wrote an algorithm for Babbage's Analytical Engine that many historians consider the first published computer program.

Significance requires stating what Lovelace accomplished and why it mattered. Only C names her algorithm and its status as the first published computer program. A and D give only biographical background, and B centers on Babbage rather than Lovelace.

Why the other answers are wrong

A. Ada Lovelace lived in nineteenth-century England and knew Charles Babbage.
Living in England and knowing Babbage is biographical background, not an accomplishment — the goal asks why Lovelace matters historically, which requires the algorithm.
B. Charles Babbage proposed a machine called the Analytical Engine.
This makes Babbage and his machine the subject; the goal is to explain Lovelace's significance, so the sentence needs to center on what she did.
D. Ada Lovelace lived during the nineteenth century, a period of rapid technological change.
This places Lovelace in a time period but names nothing she accomplished — historical significance requires stating her achievement, not the era's general character.
