How much stronger is Kevlar than steel?

  • A.Half as strong
  • B.As strong
  • C.Five times as strong
  • D.200 times as strong

Answer: C

Kevlar is five times as strong as steel.

The first paragraph describes a fibre 'as flexible and lightweight as nylon yet five times stronger than steel', and goes on to name it as Kevlar.

'Half as strong' and 'as strong' understate it, and 200 times is not in the passage.
