Information and Ideas practice question

Bubble wrap was invented in 1957 as a textured wallpaper. It failed as decoration, was tried as greenhouse insulation, and found its real use only when a computer company needed something to protect fragile machines in transit.

Which choice best states the main idea of the text?

  1. A. Bubble wrap found its purpose only after failing at the uses it was invented for.Correct
  2. B. Bubble wrap was designed from the start for shipping computers.
  3. C. Bubble wrap became a popular wallpaper.
  4. D. Bubble wrap works well as greenhouse insulation.

Wallpaper failed, insulation was tried, packaging succeeded — the text traces a product to its accidental use.

Why the other answers are wrong

B. Bubble wrap was designed from the start for shipping computers.
The text says it was invented as wallpaper.
C. Bubble wrap became a popular wallpaper.
It 'failed as decoration'.
D. Bubble wrap works well as greenhouse insulation.
Insulation was only 'tried'; its real use came later.
