• Question 1:

  Greyhound racing is the sixth most popular spectator sport in the United States. Over the last decade a growing number of racers have been adopted to live out their retirement as household pets, once their racing career is over. Many people hesitate to adopt a retired racing greyhound because they think only very old dogs are available. Actually, even champion racers only work until they are about three and a half years old. Since greyhounds usually live to be 12-15 years old, their retirement is much longer than their racing careers. People worry that a greyhound will be more nervous and active than other breeds and will need a large space to run. These are false impressions. Greyhounds have naturally sweet, mild dispositions, and while they love to run, they are sprinters rather than distance runners and are sufficiently exercised with a few laps around a fenced-in backyard everyday. Greyhounds do not make good watchdogs, but they are very good with children, get along well with other dogs (and usually cats as well), and are very affectionate and loyal. They are intelligent, well behaved dogs, usually housebroken in only a few days. A retired racing greyhound is a wonderful pet for almost anyone. On the basis of above passage please answer the following question According to the passage, adopting a greyhound is a good idea for people who

  A. do not have children.

  B. live in apartments.

  C. do not usually like dogs.

  D. are retired.

  E. already have another dog or a cat.

  Correct Answer: E

  See the last paragraph. The passage does not mention b, c, or d. Choice a is clearly wrong; the passage states the opposite.

• Question 2:

  By using tiny probes as neural prostheses, scientists may be able to restore nerve function in quadriplegics and make the blind see or the deaf hear. Thanks to advanced techniques, a single, small, implanted probe can stimulate individual neurons electrically or chemically and then record responses. Preliminary results suggest that the microprobe telemetry systems can be permanently implanted and replace damaged or missing nerves. The tissue-compatible microprobes represent an advance over the typical aluminum wire electrodes used in studies of the cortex and other brain structures. Researchers accumulate much data using traditional electrodes, but there is a question of how much damage they cause to the nervous system. Microprobes, which are about as thin as a human hair, cause minimal damage and disruption of neurons when inserted into the brain. In addition to recording nervous system impulses, the microprobes have minuscule channels that open the way for delivery of drugs, cellular growth factors, neurotransmitters, and other neuroactive compounds to a single neuron or to groups of neurons. Also, patients who lack certain biochemicals could receive doses via prostheses. The probes can have up to four channels, each with its own recording/stimulating electrode. On the basis of above passage please answer the following question The initial function of microprobe channels is to

  A. create pathways.

  B. disrupt neurons.

  C. replace ribbon cables.

  D. study the brain.

  E. induce sight and hearing in the blind and deaf.

  Correct Answer: A

  The first sentence of the third paragraph says that microprobes have channels that open the way for delivery of drugs. Studying the brain (choice d) is not the initial function of channels, though it is one of the uses of the probes themselves.

They are intelligent, well behaved dogs, usually housebroken in only a few days. A retired racing greyhound is a wonderful pet for almost anyone. On the basis of above passage please answer the following question Based on the tone of the passage, the authors main purpose is to

  A. teach prospective owners how to transform their racing greyhound into a good pet.

  B. show how the greyhound's nature makes it equally good as racer and pet.

  C. encourage people to adopt retired racing greyhounds.

  D. objectively present the pros and cons of adopting a racing greyhound.

  E. argue in favor of banning Greyhound racing.

  Correct Answer: C

  The tone of the passage is enthusiastic in its recommendation of the greyhound as pet and thereby encourages people to adopt one. It does not give advice on transforming a greyhound (choice a). Except to say that they love to run, the passage does not spend equal time describing the greyhound as racer (choice b), nor does it comment on banning of greyhound racing (choice e). The authors tone is not objective (choice d), but rather enthusiastic.

Also, patients who lack certain biochemicals could receive doses via prostheses. The probes can have up to four channels, each with its own recording/stimulating electrode. On the basis of above passage please answer the following question Which of the following best expresses the main idea of the passage?

  A. Microprobes require further technological advances before they can be used in humans.

  B. Wire electrodes are antiquated as a means for delivering neuroactive compounds to the brain.

  C. Microprobes have great potential to help counteract neural damage.

  D. Technology now exists that may enable repair of the nervous system.

  E. Use of wire electrodes is being replaced by use of wire electrodes.

  Correct Answer: C

  The tone throughout the passage suggests the potential for microprobes. They can be permanently implanted, they have advantages over electrodes, they are promising candidates for neural prostheses, they will have great accuracy, and they are flexible.

Also, patients who lack certain biochemicals could receive doses via prostheses. The probes can have up to four channels, each with its own recording/stimulating electrode. On the basis of above passage please answer the following question All of the following are mentioned in the passage as potential uses for prostheses EXCEPT

  A. transportation of medication.

  B. induction of physical movement.

  C. compensation for damaged nerves.

  D. transportation of growth factor.

  E. removal of biochemicals from the cortex.

  Correct Answer: E

  According to the third paragraph, people who lack biochemicals could receive doses via prostheses. However, there is no suggestion that removing biochemicals would be viable.

• Question 6:

  A narrow fellow in the grass Occasionally rides;

  You may have met himdid you not?

  His notice sudden is.

  The grass divides as with a comb,

  A spotted shaft is seen,

  And then it closes at your feet And opens further on.

  He likes a boggy acre,

  A floor too cool for corn,

  Yet when a boy, and barefoot,

  I more than once at noon Have passed, I thought, a whip-lash

  Unbraiding in the sun,

  When, stooping to secure it,

  It wrinkled, and was gone.

  Several of natures people I know and they know me;

  I feel for them a transport Of cordiality;

  But never met this fellow,

  Attended or alone,

  Without a tighter breathing And zero at the bone.

  On the basis of above poem please answer the following question

  The phrase "nature's people" means

  A. nature-lovers.

  B. children.

  C. animals.

  D. neighbors.

  E. grain.

  Correct Answer: C

  In context, the speaker is discussing animals, because he follows with his contrasting attitude toward this fellow, meaning the snake. The other choices are all human beings.

  The grass divides as with a comb,

  A spotted shaft is seen,

  And then it closes at your feet And opens further on.

  He likes a boggy acre,

  It wrinkled, and was gone.

  Several of natures people I know and they know me;

  I feel for them a transport Of cordiality;

  But never met this fellow,

  Attended or alone,

  The speaker of this poem is most likely

  A. an adult woman.

  B. an adult man.

  C. a young girl.

  D. a young boy.

  E. Emily Dickinson.

  Correct Answer: B

  Stanza three contains the phrase when a boy implying the speaker was a boy in the past and is now, therefore, an adult man.

  A. a minimal disturbance of neurons.

  B. the density of the material.

  C. the capacity for multiple leads.

  D. the substance from which they are made.

  E. their ability to generate information.

  Correct Answer: E

  The second sentence of the first paragraph states that probes record responses. The second paragraph says that electrodes accumulate much data.

  The phrase "Without a tighter breathing / And zero at the bone" most nearly indicates

  A. fright.

  B. cold.

  C. grief.

  D. awe.

  E. relief.

  Correct Answer: A

  Tighter breathing indicates fear, as does zero at the bone(one is sometimes said to be cold with fear). Also, the subject is a snake, which is generally feared animal.
