Completes Passage Question No. 1

 

Which of the following most logically completes the passage?

 

Using new detection techniques, researchers have found trace amounts of various medicinal substances in lakes and rivers. Taken in large quantities, these substances could have serious health effects, but they are present in quantities far too low to cause any physiological response in people who drink the water or bathe in it. Nevertheless, medical experts contend that eliminating these trace amounts from the water will have public health benefits, since ____________.

(E) disease-causing bacteria exposed to low concentrations of certain medicinal substances can become resistant to them

 

 

Completes Passage Question No. 2

 

Which of the following most logically completes the argument below?

 

Twenty percent of the stores in Morganville's downtown shopping district will fail within five years because they will be competing directly with the SaveMart discount department store newly opened in East Morganville. The downtown shopping district has lost business at this rate before and has always completely rebounded. Confidence that it will rebound again from the losses it is now about to suffer is ill founded, however, because ________ .

 

(A) the stores likely to be put out of business by direct competition from SaveMart are the downtown shopping district's anchor stores, on whose ability to draw shoppers many of the other downtown stores depend.

(B) the bus line that has long connected the downtown area of Morganville with EastMorganville has a tradition of carrying shoppers who reside in EastMorganville into downtown Morganville to shop.

(C) when the downtown shopping district has rebounded before, the business premises of a failed business were typically taken over by a business of same kind as had been there before

(D) SaveMart's business plan for the EastMorganvill store is based on earning low profits, if any, during the first five years of the store's existence.

Completes Passage Question No. 3

 

Which of the following most logically completes the argument?

 

When people engage in activities that help others, their brain releases endorphins, the brain’s natural opiates, which induce in people a feeling of well-being. It has been suggested that regular release of endorphins increases people’s longevity. And a statistic on adults who regularly engage in volunteer work helping others shows that they live longer, on average, than adults who do not volunteer. However, that statistic would be what we would expect even if volunteering does not boost longevity, because _______.

 

(A) in the communities studied, women were much more likely to do regular volunteer work than men were, and women tend to live longer than men do.

(B) the number of young adults who do regular volunteer work is on the increase.

(C) the feelings of well-being induced by endorphins can, at least for a time, mask the symptoms of various conditions and diseases, provided the symptoms are mild.

(D) it is rare for a person to keep up a regular schedule of volunteer work throughout his or her life.

(E) Some people find that keeping a commitment to do regular volunteer work becomes a source of stress in their lives.

Completes Passage Question No. 7

Completes Passage Question No. 8

 

Commentator: In the new century, only nations with all the latest electronic technology will experience great economic prosperity.

Completes Passage Question No. 9

 

Insurgent political parties that are profoundly dissatisfied with the dominant party’s reign and justificatory ideology always produce factions whose views and aims differ as greatly from each other’s as they do from the dominant party’s.

Completes Passage Question No. 10

 

Which of the following most logically completes the passage?

 

Appendicitis (inflammation of the appendix) is potentially fatal; consequently, patients with symptoms strongly suggesting appendicitis almost always have their appendix removed. The appropriate surgery is low-risk but performed unnecessarily in about 20 percent of all cases. A newly developed internal scan for appendicitis is highly accurate, producing two misdiagnoses for every 98 correct diagnoses. Clearly, using this test, doctors can largely avoid unnecessary removals of the appendix without, however, performing any fewer necessary ones than before, since __________.

 

(A) the patients who are correctly diagnosed with this test as not having appendicitis invariably have medical conditions that are much less serious than appendicitis

(B) the misdiagnoses produced by this test are always instances of attributing appendicitis to someone who does not, in fact, have it

(C) all of the patients who are diagnosed with this test as having appendicitis do, in fact, have appendicitis

(D) every patient who is diagnosed with this test as having appendicitis has more than one of the symptoms generally associated with appendicitis

(E) the only patients who are misdiagnosed using this test are patients who lack one or more of the symptoms that are generally associated with appendicitis
