Since the world has become industrialized, there has been an increase in the number of animal species that have either become extinct or have neared extinction. Bengal tigers, for instance, which once roamed the jungles in vast numbers, now number only about 2,300, and by 5 the year 2025 their population is estimated to be down to zero. What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who, according to some sources, are not interested in material gain but in personal gratification. This is an example of the callousness that is part 10 of what is causing the problem of extinction. Animals like the Bengal tiger, as well as other endangered species, are a valuable part of the world's ecosystem. International laws protecting these animals must be enacted to ensure their survival, and the survival of our planet.
15 Countries around the world have begun to deal with the problem in various ways. Some countries, in order to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission to help defray the costs of maintaining the parks, 20 and they often must also depend on world organizations for support. With the money they get, they can invest in equipment and patrols to protect the animals. Another solution that is an attempt to stem the tide of animal extinction is an international boycott of products made from endangered species. This seems fairly effective, but it 25 will not, by itself, prevent animals from being hunted and killed.

The peregrine falcon, a predatory bird indigenous to North America, was once in danger of extinction. In the 1960s, scientists discovered byproducts of the pesticide DDT in the birds' eggs, which caused them to be too soft to survive. The use of the pesticide had been 5 banned in the United States, but the falcons were eating migratory birds from other places where DDT was still used. In order to increase the survival rate, scientists were raising the birds in laboratories and then releasing them into mountainous areas. This practice achieved only moderate success, however, because many of the birds raised 10 in captivity could not survive in the wild.

There is now, however, a new alternative to releases in the wild. A falcon that has been given the name Scarlett chose to make her home on a ledge of the 33rd floor of a Baltimore, Maryland, office 15 building rather than in the wild, and, to the surprise of the scientists, she has managed to live quite well in the city. Following this example, programs have been initiated that release birds like Scarlett into cities rather than into their natural wild habitat. These urban releases are becoming a common way to strengthen the species. Urban homes 20 have several benefits for the birds that wild spots do not. First, there is an abundance of pigeons and small birds as food sources. The peregrine in the city is also protected from its main predator, the great horned owl. Urban release programs have been very successful in reestablishing the peregrine falcons along the East Coast. Though 25 they are still an endangered species, their numbers increased from about 60 nesting pairs in 1975 to about 700 pairs in 1992. In another decade the species may flourish again, this time without human help.

(A) survival of peregrine falcons
(B) releases into the wild

2. In line 1, the phrase "indigenous to" could be best replaced by
(A) typical of

3. The word "byproducts" in line 3 could best be replaced by which of the following?

6. In line 7, the word "raising" most probably means
(A) breeding
(B) elevating
(C) collecting
(D) measuring
7. Why were the peregrine falcons in danger?
(A) because of pesticides used by American farmers
(B) because they migrated to countries where their eggs could not survive
(C) because they ate birds from other countries where DDT was still used
(D) because they were prized by hunters and hunted to near extinction
8. The word "releases" as used in line 12 most probably means

A balanced diet contains proteins, which are composed of complex amino acids. There are 20 types of amino acids, comprising about 16 percent of the body weight in a lean individual. A body needs all 20 to be healthy. Amino acids can be divided into two groups: essential 5 and nonessential. There are 9 essential amino acids. These are the proteins that the body cannot produce by itself, so a healthy individual must ingest them. The 11 nonessential amino acids, on the other hand, are produced by the body, so it is not necessary to ingest them. Proteins are described as being either high-quality or low-quality, 10 depending on how many of the 9 essential amino acids the food contains. High-quality proteins, typically found in animal meats, are proteins that have ample amounts of the essential amino acids. Low-quality proteins are mainly plant proteins and usually lack one or more of the essential amino acids. Since people who follow a strict vegetarian 15 diet are ingesting only low-quality proteins, they must make sure that their diets contain a variety of proteins, in order to ensure that what is lacking in one food is available in another. This process of selecting a variety of the essential proteins is called protein complementation. Since an insufficient amount of protein in the 20 diet can be crippling, and prolonged absence of proteins can cause death, it is imperative that a vegetarian diet contains an ample amount of the essential proteins.

A balanced diet contains proteins, which are composed of complex amino acids. There are 20 types of amino acids, comprising about 16 percent of the body weight in a lean individual. A body needs all 20 to be healthy. Amino acids can be divided into two groups: essential 5 and nonessential. There are 9 essential amino acids. These are the proteins that the body cannot produce by itself, so a healthy individual must ingest them. The 11 nonessential amino acids, on the other hand, are produced by the body, so it is not necessary to ingest them. Proteins are described as being either high-quality or low-quality, 10 depending on how many of the 9 essential amino acids the food contains. High-quality proteins, typically found in animal meats, are proteins that have ample amounts of the essential amino acids. Low-quality proteins are mainly plant proteins and usually lack one or more of the essential amino acids. Since people who follow a strict vegetarian 15 diet are ingesting only low-quality proteins, they must make sure that their diets contain a variety of proteins, in order to ensure that what is lacking in one food is available in another. This process of selecting a variety of the essential proteins is called protein complementation. Since an insufficient amount of protein in the 20 diet can be crippling, and prolonged absence of proteins can cause death, it is imperative that a vegetarian diet contains an ample amount of the essential proteins.

Martin Luther King, Jr., is well known for his work in civil rights and for his many famous speeches, among them is his moving "I Have A Dream" speech. But fewer people know much about King's childhood. M.L., as he was called, was born in 1929 in Atlanta, Georgia, at 5 the home of his maternal grandfather. M.L.'s grandfather, the ReverendA.D. Williams, purchased their home on Auburn Avenue in 1909, twenty years before M.L. was born. The Reverend Williams, an eloquent speaker, played an important role in the community since so many people's lives centered around the church. He allowed his church and his home 10 to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. M.L. grew up in this atmosphere, with his home being used as a community gathering place, and was no doubt influenced by it.

15 M.L.'s childhood was not especially eventful. His father was a minister and his mother was a musician. He was the second of three children, and he attended all- black schools in a black neighborhood. The neighborhood was not poor, however. Auburn Avenue was the main artery through a prosperous neighborhood that had come to symbolize achievement 20 for Atlanta's black people. It was an area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers, and other black-owner black-operated businesses and services. Even in the face of Atlanta's segregation, the district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice 25 that was a seemingly insurmountable barrier that kept black Atlantans from mingling with whites.
