Verbal Reasoning:

Read the following passage and answer the questions that follow:

There is no doubt that Americans today place a high priority on living a long and disease-free life. It is generally conceded that freedom from pain and debilitation ought to be looked upon as a natural right of all human beings. Achieving this goal is facilitated by the proper selection of health products and services.

Of all consumer goods and services, none is more essential to one's welfare than health care. There are several excellent consumer magazines distributed by product-testing agencies that may be helpful in choosing health care. Yet the array of products and medical facilities is huge, and the claims for the merits of each are confusing. Occasionally, we may visit a physician or dentist and receive specific care or advice, but few of us can afford professional counsel on all health matters.

Not only can we waste a great deal of money on ineffectual products and professionals, but our health, perhaps even our lives, may depend on getting proper treatment for disease and illness. There are times when self-treatment should not even be attempted. For example, some products—such as aspirin, laxatives, and antihistamines—are dangerous when used in excessive amounts, in the presence of certain physical disorders, or in combination with other medicines. In addition to the question of which products to select, there is always the question of whether any product should be selected without the consultation of a physician.

Obviously, people should not run to a physician for every little scrape, bruise, ache, or pain. If they did, our entire system of medical care would be swamped overnight and the doctors would be unable to take care of the more serious problems. How can we know then, which of the hundreds of different symptoms that can develop require the services of a physician? There are several circumstances under which a physician should always be consulted.

1. Severe symptoms. Any type of attack in which the symptoms are severe or alarming—such as severe abdominal or chest pain, or bleeding—should obviously receive prompt medical attention
2. Prolonged symptoms. Any symptoms—such as cough, headache, constipation, or fatigue—that persist day after day should be checked by a physician, even though the symptoms are minor. Serious chronic disorders are often revealed through persistent minor symptoms.
3. Repeated symptoms. Symptoms, even though minor, that recur time after time should be reported to a physician because, like prolonged symptoms, they may indicate a serious problem
4. Unusual symptoms. Any symptoms that seem to be unusual, such as unusual bleeding, mental changes, weight gain or loss, digestive changes, or fatigue, call for a visit to a physician
5. If in doubt, the safest action is to see a physician. If there is a serious problem, it can be corrected in its early stages; if there is no problem, then you have paid a very small price for your piece of mind

Writing Sample:

A popular fear of Americans is that our nation will be "one large paved parking lot with border to border interstate highways connecting it."

Write an essay in which you perform the following tasks: explain what you think the statement means; describe specific situations in which there is evidence of a growing change in the countryside of this nation; discuss ways that the statement may not be necessarily true; provide evidence of what this means to today’s society; conclude with a justification of the positive or negative implications.

Biological Science:

A variety of staining techniques are routinely used in the microbiology laboratory to identify bacteria. Some stains are simple stains while others are differential. Many of the basic dyes used bind to the bacterial cell due to its negatively charged surface. Other dyes may be repelled by the cell, and can be used to produce a negative stain. The choice of technique depends on the type of information needed. The information is routinely used to help identify microorganisms, and it also helps determine appropriate therapeutic treatment.

The most widely-used differential stain for bacteria is:

(A) the capsule stain.
(B) the Gram stain.
(C) the endospore stain.
(D) the flagella stain.

2. True statements about the brain are all of the following EXCEPT

(A) The pons functions to link the cerebellum with the higher conscious centers.
(B) The limbic system alerts the cortex of incoming stimuli.
(C) The limbic system is associated with emotional responses.
(D) The nuclei of cranial nerves 5,6, 7, and 8 are located in the pons.
