Information and Ideas practice question

In 1894 a newspaper predicted that by 1950 every street in London would be buried under nine feet of horse manure. The prediction was arithmetically sound and entirely wrong: it extended the growth of horse traffic without imagining that anything might replace the horse.

Which choice best states the main idea of the text?

  1. A. The prediction failed not because its calculation was wrong but because it assumed the future would only extend the present.Correct
  2. B. London's streets were buried in manure by 1950.
  3. C. Newspapers in 1894 were poor at arithmetic.
  4. D. Horse traffic in London stopped growing in 1894.

Answer: A. The prediction failed not because its calculation was wrong but because it assumed the future would only extend the present.

'Arithmetically sound and entirely wrong': the failure was of imagination, not calculation.

Why the other answers are wrong

B. London's streets were buried in manure by 1950.
The prediction was 'entirely wrong'.
C. Newspapers in 1894 were poor at arithmetic.
The arithmetic was sound.
D. Horse traffic in London stopped growing in 1894.
The text says nothing about when horse traffic stopped growing.
