Problem:"Beauty and the Beast" is a song written by lyricist Howard Ashman and composer Alan Menken for the Disney animated feature film Beauty and the Beast (1991). The film's theme song, the Broadway-inspired ballad was first recorded by British-American actress Angela Lansbury in her role as the voice of the character Mrs. Potts, and essentially describes the relationship between its two main characters Belle and the Beast, specifically how the couple has learned to accept their differences and in turn change each other for the better. Additionally, the song's lyrics imply that the feeling of love is as timeless and ageless as a "tale as old as time". Lansbury's rendition is heard during the famous ballroom sequence between Belle and the Beast, while a shortened chorale version plays in the closing scenes of the film, and the song's motif features frequently in other pieces of Menken's film score.

Problem:In 1971, research chemist Stephanie Kwolek discovered a liquid crystalline polymer solution. Its exceptional strength and stiffness led to the invention of Kevlar ®, a synthetic fibre, woven into a fabric and layered, that, by weight, has five times the tensile strength of steel. In the mid-1970s, DuPont the company which employed Kwolek introduced Kevlar. Immediately Kevlar was incorporated into a National Institute of Justice (NIJ) evaluation program to provide lightweight, able body armor to a test pool of American law enforcement officers to ascertain if everyday able wearing was possible. Lester Shubin, a program manager at the NIJ, managed this law enforcement feasibility study within a few selected large police agencies, and quickly determined that Kevlar body armor could be comfortably worn by police daily, and would save lives.
