Question

Aspirin origin go back at least as early as 1758. In that year, Englishman Edward Stone noticed a distinctive bitter flavor in the bark of the willow tree. To stone, this particular bark seemed to have much in common with peruvian bark which had been used medicinally since the 1640s to bring down fever and to treat malaria. Stone decided to test the effectiveness of the willow bark. He obtained some, pulversized it into tiny pieces, and conducted experiments on it properties. His tests demonstrated that this pulverized willow bark was effective both in reducing high temperatures and in relieving aches and pains. In 1763, tone presented his findings to the british royal society.

Several decades later, further studies on the medicine value of the willow bark were being conducted by two Italian scientists. These chemicals, brugnatelli and montana, determined that the active chemical that was responsible for the medicinal characteristics in the willow bark was the chemical salicin, which is the active ingredient of todays aspirin.

The name aspirin is the trade name of the drug based on the chemical salicin, properly known as acetylsali- cylic acid. The trade name aspirin was invented for the drug in the 1980s by the layer drug company in Germany. The first bottles of aspirin actually went on sale to the public just prior to the turn of the century, in 1899.

10. The pronoun "it" in "He obtained some, pulversized it into tiny pieces, and conducted experiments on it properties." refers to ...
a. willow bark
