LANGUAGE OF CHIMPANZEES

A. A simple way to disprove this Innateness Hypothesis, as linguists call it, is to demonstrate that other species have the capacity to speak but for some reason simply have not developed speech.
B. A logical candidate for such a species is the chimpanzee, which shares 98.4% of the human genetic code.
C. Chimpanzees cannot speak because, unlike humans, their vocal cords are located higher in their throats and cannot be controlled as well as human vocal cords.
D. It does not follow from their lack of speech, however, that chimpanzees are incapable of language, that is, a human-like grammar.
E. Perhaps they can acquire grammar and speak if they could only use grammar some way other than with a voice. The obvious alternative is sign language

WEB SECURITY

A. In the lobby of Google’s headquarters in Mountain View, California, computer screens display lists of the words being entered into the company’s search engine.
B. Although Google says the system is designed to filter out any scandalous or potentially compromising queries, the fact that even a fraction of searches can be seen by visitors to the world’s biggest search company is likely to come as a shock to internet users who think of web browsing as a private affair.
C. That may be changing.
D. Over the past year, a series of privacy gaffes and government attempts to gain access to internet users’ online histories have, along with consolidation among online search and advertising groups, thrust the issue of internet privacy into the spotlight.
E. This presents a challenge to Google and other internet search companies, which have built a multi-billion dollar industry out of targeted advertising based on the information users reveal about themselves online.

LINGUISTICS

A. It is wrong, however, to exaggerate the similarity between language and other cognitive skills, because language stands apart in several ways.

B. For one thing, the use of language is universal—all normally developing children learn to speak at least one language, and many learn more than one.

C. By contrast, not everyone becomes proficient at complex mathematical reasoning, few people learn to paint well, and many people cannot carry a tune.

D. Because everyone is capable of learning to speak and understand language, it may seem to be simple.

E. But just the opposite is true—language is one of the most complex of all human cognitive abilities.

JET STREAM

A. Jet stream, narrow, swift currents or tubes of air found at heights ranging from 7 to 8 mi (11.3–12.9 km) above the surface of the earth.

B. They are caused by great temperature differences between adjacent air masses.

C. Instead of moving along a straight line, the jet stream flows in a wavelike fashion; the waves propagate eastward (in the Northern Hemisphere) at speeds considerably slower than the wind speed itself.

D. Since the progress of an airplane is aided or impeded depending on whether tail winds or head winds are encountered, in the Northern Hemisphere the jet stream is sought by eastbound aircraft, in order to gain speed and save fuel, and avoided by westbound aircraft.
