Khan Academy Practice Passage Question From 'Tools of Thought'

[PWF]

Question number 4 asks "Which of the following passage assertions is most supported in the passage by evidence or examples?"

• A) Computational objects have an impact on students’ ideas about their emotional lives.
• 
  B) When students used slide rules, they had to insert decimal points themselves.
• 
  
  C) Students who used calculators lost their ability to do “back of the envelope” calculations.
• 
  
  
  D) The invention of written language brought about a radical shift in how we process, organize, store, and transmit representations of the world.

Why would the answer not be D? I still think that reading a calculator, writing code for open/closed, and reading freud wouldn't exist without written language, yet the answer is C.
