Question Analysis:
The question asks for the percent increase in the fraction of employees who owned cell phones from 1994 to 1998. We are given that 20% of the employees owned cell phones in 1994 and 60% of the employees owned cell phones in 1998. To find the percent increase, we need to calculate the difference between the two percentages and express it as a percentage of the initial value.

Given:
- Fraction of employees who owned cell phones in 1994 = 20%
- Fraction of employees who owned cell phones in 1998 = 60%

Solution:
To find the percent increase, we need to calculate the difference between the two percentages and express it as a percentage of the initial value.

Step 1: Calculate the difference between the two percentages:
Difference = Fraction in 1998 - Fraction in 1994
Difference = 60% - 20%
Difference = 40%

Step 2: Calculate the percent increase:
Percent Increase = (Difference / Fraction in 1994) * 100
Percent Increase = (40% / 20%) * 100
Percent Increase = 2 * 100
Percent Increase = 200%

Answer:
Therefore, the percent increase in the fraction of employees who owned cell phones from 1994 to 1998 is 200%.

Directions: After reading the passage, read and respond to the questions that follow by selecting the best choice for each one. Statins are a class of drugs that work to decrease the level of cholesterol in the blood. They are able to perform this function by effectively blocking the cholesterol-producing enzyme in the liver. In recent years, statins have increased in utility and popularity. Although a certain amount of cholesterol is imperative for the human body to function, an elevated level can cause a precarious situation in the body. Cholesterol affixes itself to arteries, lining them and inhibiting blood flow. Since less blood can travel through those encumbered arteries, the blood flow to the heart is adversely affected. Scientists have found that the walls of arteries in the body can become inflamed from this plaque buildup. In many instances, the end result of this decreased blood supply and inflammation is a heart attack sometimes a fatal one. In other cases the blood supply to the brain is compromised by the plaque buildup, often causing a stroke. Decreased blood flow to the legs can cause leg pains or cramps. In short, arterial plaque buildup is never a healthy situation.Statins diminish the amount of cholesterol generated by the body. Although the drugs are not always able to reduce the amount of plaque that may already be clogging arteries, they can slow the production of new plaque. The drugs are also able to stabilize the plaques that are already present and make them less likely to cause problems in the body.Lowered cholesterol does not guarantee that a heart attack won’t occur, but statin use will lower the risk for most patients. Not everyone who has a heart attack has high cholesterol levels, but most do have plaque formations on their arteries. It should be noted that the plaque is not always formed by high levels of cholesterol in the blood.Statins are generally prescribed by doctors for people with elevated cholesterol levels. As the mean weight of the American population has risen, so has the number of individuals with high cholesterol. Millions of men and women in this country are prescribed statins in an effort to decrease the amount of cholesterol in their blood. Remarkably, these effects can be seen in as little as two weeks after beginning a statin regime.Q. The author concedes that statins’ job is primarily to

Direction: Read the following passage carefully and answer the questions given below it.According to a recent survey from the National Institute for Drug Abuse, more U.S. adolescents smoke marijuana than smoke cigarettes.The organization’s annual survey revealed an increase in marijuana use among all teen groups and a slight decrease in tobacco use among high-school seniors compared to past years. Federal officials speculate that teens are starting to listen to the warnings about the risks of tobacco use but are receiving mixed messages about the safety of marijuana use. While antidrug organizations such as Drug-Free America maintain their message that marijuana impairs judgment andhampers brain development, clinical studies support the medicinal benefits of marijuana, particularly for those suffering from certain cancers and Crohn’s disease. These studies have sparked a national debate about the legalization of marijuana. More than a dozen states and the District of Columbia have legalized the use of medical marijuana, and there is a push for the nationwide legalization of the drug. The White House Office of National Drug Control Policy asserts that the message that marijuana use is okay for some is dangerous.The office insists that both policy makers and the general public should be aware of the effect the debate over the legalization of marijuana has on teens’ perception of the drug’s risk.Q. The passage predicts which of the following would follow the legalization of marijuana?
