Answer

Brief Explanations:

  1. The problem "The solution was thin and cloudy" was solved by using a laboratory spinneret as stated in the text where it says she spun the solution in a spinneret.
  2. The problem "Kwolek's team needed a replacement for steel in tires" was solved by developing Kevlar as they were searching for a lightweight fiber to replace steel and ended up with Kevlar.
  3. The problem "Kwolek wanted to demonstrate how to prepare synthetic materials" was solved by developing the nylon rope trick as she invented it to help students understand making materials like Kevlar.

Answer:

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