In 1998, observations of a (i) ________ in the growth of atmospheric methane, a potent greenhouse gas, suggested that many of the scenarios for global warming provided in a 1995 assessment may have been overly (ii) _______. Celebration was, however, premature: subsequent research has established that the observed phenomena were likely caused by (iii) _______ declines in industrial and natural emissions.

For South Korea’s Gyeongbu highway to be a symbol of industrialization and modernization the view from the road mattered. Before the highway opened, farming villages were compelled to replace traditional grass roofs with modern-looking tiled roofs-at least on the side facing the highway. Farmers were encouraged to harvest their barley and plant rice to furnish verdant scenery. The desire to create magnificent scenery may have affected the design of the highway itself. One journalist guessed that, despite the general principle that a highway should follow the shortest path, it had been designed to detour through an area with access to Gyeongju, a historic capital and tourist destination, and a distant view of Ulsan, a rising industrial city.

When Eric Temple Bell, in his 1937 work Men of Mathematics, related the anecdote about German mathematician Carl Gauss’s precocious summation of integers as a schoolboy, he was (i)      one of his (ii)      : Bell had always been praised as a highly (iii)      writer, but in this case it undermined his credibility as a biographer.

Anyone who thinks that the contemporary media's focus on celebrity gossip and rumor marks some sort of journalistic (i)      will find in this book (ii)      . The book shows that we live, on the contrary, in a hitherto unexampled golden age of (iii)      .

Which of the following is equivalent to 36^-1?

In explaining his opposition to efforts aimed at stabilizing moose populations and at suppressing fires in northern forests, Pastor points out that moose, by feeding on hardwood trees, contribute to a characteristic process whereby hardwood trees are eventually overtaken and shaded out as conifers such as spruces block sunlight A decline in hardwood trees leads to fewer nitrogen-rich, quick-rotting leaves on the forest floor which is increasingly carpeted with slower-rotting conifer needles. Hardwoods require more nitrogen for growth than do conifers, so the decline in soil fertility in areas where moose feed reinforces the advance of conifers. But conifers cannot dominate the forest for long, because mature conifer forests are more combustible than are hardwood forests. Fire combined with high winds, attacks of spruce budworm, or even a greatly diminished nitrogen supply will destroy expanses of spruces, allowing hardwoods to recolonize in the nutrient-rich ash. Such oscillations in forest composition and consequently in moose population are, Pastor believes, essential to the integrity and functioning of northern forest ecosystems.

Even those observers who are the most _____ about genetic privacy issues would have to concede that genetic discrimination is rare: there have only been two cases of any notoriety. 

The probability that event A will occur is 0.8, and the probability that event B will occurs is 0.6. If x is the probability that events A and B will both occur, which of the following must be true?

While there is nothing                 about the periodic disintegrations of the Chinese empire, its repeated resurrection within more or less the same boundaries clearly distinguishes China from other continental powers.
