1 [Y(ji)]These plants are termed opportunists because [ԭ]they rely on their seeds’falling into settings where competing plants have been removed by natural processes, such asalong an eroding riverbank, on landslips, or where a tree falls and creates a gap in the forestcanopy.

A. Because [ԭ]their seeds grow in places where competing plants are no longer present, [Y(ji)]dandelions are classified as opportunists.

B. [Y(ji)]Dandelions are called opportunists because [ԭ]they contribute to the naturalprocesses of erosion and the creation of gaps in the forest canopy.

A. Despite the current impressive size of the Ogallala aquifer, the region’s climate keepsthe rates of water addition very small.

B. Although the aquifer has been adding water at the rate of only half a centimeter a year,it will eventually accumulate enough water of fill Lake Huron.

Paragraph 3: … However, as the storm cloud develops, the ground beneath the cloudbecomes positively charged and lightning can take place in the form of an electrical dischargebetween the negative charge of the cloud and the positively charged ground. Lightning thatstrikes the ground is the most likely to be destructive, so [even though it represents only 20percent of all lightning, it has received a lot of scientific attention].

The author remarks that “Lightning that strikes the ground is the most likely to bedestructive” in order to explain why

this form of lightning has been investigated so much

this form of lightning is not as common as lightning within a cloud

scientific understanding of this form of lightning is important

the buildup of positive charge on the ground beneath a storm cloud can have seriousconsequences

Paragraph 1: The city of Teotihuacán, which lay about 50 kilometers northeast of modern-day Mexico City, began its growth by 200-100 B.C. At its height, between about A.D. 150 and700, it probably had a population of more than 125,000 people and covered at least 20 squarekilometers. A. It had over 2,000 apartment complexes, a great market, a large number ofindustrial workshops, an administrative center, a number of massive religious edifices, and aregular grid pattern of streets and buildings. B. Clearly, much planning and central controlwere involved in the expansion and ordering of this great metropolis. C. Moreover, the cityhad economic and perhaps religious contacts with most parts of Mesoamerica (modern CentralAmerica and Mexico). D.

————————————————————————————————

In fact, artifacts and pottery from Teotihuacán have been discovered in sites as far away asthe Mayan lowlands, the Guatemalan highlands, northern Mexico, and the Gulf Coast of Mexico.

Paragraph 5: Even the kind of stability defined as simple lack of change is not alwaysassociated with maximum diversity. At least in temperate zones, maximum diversity is oftenfound in mid-successional stages, not in the climax community. Once a redwood forestmatures, for example, the kinds of species and the number of individuals growing on the forestfloor are reduced. In general, diversity, by itself, does not ensure stability. Mathematicalmodels of ecosystems likewise suggest that diversity does not guarantee ecosystemstability—just the opposite, in fact.

Which of the following can be inferred from paragraph 5 about redwood forests?

They become less stable as they mature.

They support many species when they reach climax.

They are found in temperate zones.

They have reduced diversity during mid-successional stages.

By the 1850’s and 1860’s, there was a great distrust among writers and intellectuals of therapid industrialization of which the railroad was a leading force. Deeply philosophicalhistorians such as Henry Adams lamented the role that the new frenzy for business was playingin eroding traditional values. A distrust of industry and business continued among writersthroughout the rest of the nineteenth century and into the twentieth.

The word lamented is closest in meaning to

complained about
