Answer

Brief Explanations:

  1. The problem of needing a replacement for steel in tires was solved by developing Kevlar as it was a lightweight fiber stronger than steel by weight.
  2. The problem of a thin and cloudy solution was solved by using a laboratory spinneret to spin the solution and produce the strong fiber.
  3. The problem of demonstrating how to prepare synthetic materials was solved by developing the nylon rope trick.

Answer:

  • Kwolek's team needed a replacement for steel in tires: Kwolek developed Kevlar.
  • The solution was thin and cloudy: Kwolek used a laboratory spinneret.
  • Kwolek wanted to demonstrate how to prepare synthetic materials: Kwolek developed the nylon rope trick.
