Which one of the following caused the search for a fabric like Kevlar?

Correct Option: A shortage in the gasoline supply

Explanation:

Kevlar was invented by chemist Stephanie Kwolek at DuPont in 1965. During the early 1960s, an anticipated energy shortage and a potential shortage in gasoline supply prompted researchers to look for lightweight yet strong materials. The main goal was to develop a high-strength, lightweight fiber to replace heavy steel cords in automobile tires, thereby improving fuel efficiency in vehicles.

While Kevlar is widely recognized today for its use in bulletproof vests to protect law enforcement personnel, the initial search and development of the polymer were directly motivated by the need for lightweight materials in response to gasoline and energy efficiency concerns.
