Write a paragraph about a discovery of scientists and link it to life today.
Example:
Michel-Eugene Chevreul made soap by reacting an animal fat and an alkali in 1816.
His discovery led to the study the nature of fats and oils and its reactions with alkali.
Today, a visit to a grocery store would bring us to a line or two of shelves displaying
a large selection of soaps, detergents, and hygiene products. I use shampoo for my
hair, clean my face with face cleanser, wash my body with liquid soap. In the kitchen,
I use dishwashing agent, while I use detergent for washing my clothes. If our budget
allows it, I also use fabric conditioner for my clothes. It's a beautiful life, farfetched
from the stories of grandmother that they used lemon to soften their hair and wood
ash to clean their pots.
