Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions.
Aspirin's origins 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 fevers and to treat malaria. Stone decided to test the effectiveness of the willow bark. He obtained some, pulverized it into tiny pieces, and conducted experiments on its properties. His tests demonstrated that this pulverized willow bark was effective both in reducing high temperatures and in relieving aches and pains. In 1763, Stone presented his findings to the British Royal Society.
Several decades later, further studies on the medicinal value of the willow bark were being conducted by two Italian scientists. These chemists, Brugnatelli and Fontana, 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 today's aspirin.
The name "aspirin" is the trade name of the drug based on the chemical salicin, properly known as acetylsalicylic acid. The trade name "aspirin" was invented for the drug in the 1890s by the Bayer 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.
What did the willow bark look like after Stone prepared it for his experiments?
A.It was in large chunks.
B.It was a thick liquid.
C.It was in strips of bark.
D.It was a rough powder.

A person with disability is defined as someone with a mental or physical impairment that substantially limits him or her in a major life activity, such as walking, talking, working, or self-care. A person with a disability may also be someone with a past record of such an impairment, for example, someone who no longer has heart disease but discriminated against because of that history.
The ADA states that employers with fifteen or more employees may not refuse to hire or promote a person because of a disability if that person is qualified to perform the job. Also, the employer must make reasonable accommodations that will allow a person with a disability to perform essential functions of the job.
All new vehicles purchased by public transit authorities must be accessible to people with disabilities. All rail stations must be made accessible, and at least one car per train is existing rail systems must be made accessible.
It is illegal for public accommodations to exclude or refuse persons with disabilities. Public accommodations are businesses and services such as restaurants, hotels, grocery stores, and parks. All new buildings must be made accessible, and existing facilities must remove barriers if the removal can be accomplished without much difficulty or expense.
