Some animals, such as dolphins, dogs, and African grey parrots, seem to exhibit cognitive functions typically associated with higher-order primates such as chimpanzees, gorillas, and humans. Some parrots, for example, have vocabularies of hundreds of words that they can string together in a comprehensible syntax. This clearly shows that humans and primates are not the only animals capable of using language to communicate. One parrot, named Alex, has been known to ask to be petted or kissed and will exhibit aggression if the gesture offered is not the specific one requested.

Which of the following, if true, would most strengthen the conclusion above?

The noise caused by airplanes during takeoff and landing imposes a large burden on people who live or work near airports. When airports operate late at night or early in the morning, the disturbance can disrupt normal sleeping patterns, even leading to severe sleep deprivation disorders. When the flight paths of airplanes lie too close to the ground, the resulting noise interferes with work performance in nearby businesses and the peaceful enjoyment of life by residents in the proximity. However, the operation of an airport, unlike a neighbor who simply plays music too loudly, provides a valuable benefit to the surrounding community, in the form of convenient transportation for both personal and economic purposes. Thus the only option is to establish standards for the reasonable operation of airports and fine those that violate the guidelines.

The bold phrase plays which of the following roles in the argument above?

As the economic role of multinational, global corporations expands, the international economic environment will be shaped increasingly not by governments or international institutions, but by the interaction between governments and global corporations, especially in the United States, Europe, and Japan. A significant factor in this shifting world economy is the trend toward regional trading blocs of nations, which has a potentially large effect on the evolution of the world trading system. Two examples of this trend are the United States-Canada Free Trade Agreement (FTA) and Europe 1992, the move by the European Community (EC) to dismantle impediments to the free flow of goods, services, capital, and labor among member states by the end of 1992. However, although numerous political and economic factors were operative in launching the move to integrate the EC’s markets, concern about protectionism within the EC does not appear to have been a major consideration. This is in sharp contrast to the FTA; the overwhelming reason for that bilateral initiative was fear of increasing United States protectionism. Nonetheless, although markedly different in origin and nature, both regional developments are highly significant in that they will foster integration in the two largest and richest markets of the world, as well as provoke questions about the future direction of the world trading system.

According to the passage, all of the following are elements of the shifting world economy EXCEPT
