Croatian-born inventor Nikola Tesla is often called the "forgotten scientist". Although he
invented the alternating current (AC) motor and developed an AC electricity generation system, he never received historical credit for many of his achievements, unlike one of his first employer and eventual nemesis, inventor Thomas Edison
Tesla made the first sketches of his idea for a brushless of his idea for a brushless AC motor while he was a student at the University of Prague in 1882. His interest in electricity generation led him to Paris where he was employed by the Continental Edison Company later that year to repair Edison's direct current (DC) power plants. Two years later, Tesla immigrated to New York City and acquired a job as an engineer at
Thomas Edison's headquarters in Manhattan. Edison was impressed with Tesla's work ethic and
ingenuity. He challenged the young scientist to develop an improved design for his DC
generators for $50,000. Tesla experimented for months, finally presenting Edison with the
solution he needed. Edison reneged on the deal, telling Tesla that he didn't understand American humor. Tesla soon left Edison in order to begin his own electric light company
Tesla filed and was granted more than 30 patents for his inventions in 1887 and 1888. He soon
had financial backing for his ideas from one of Edison' main competitors, Westinghouse. In the
1890's Tesla experimented with x-rays, developed a high-voltage electrical transformer call the
Tesla coil, and demonstrated the propagation of radio waves two years before the "Father of
Radio" Guglielmo Marconi. He was also the first to harness the mammoth potential energy of
Niagara Falls. He worked with General Electric to install AC generators with turbines driven by the falling waters of the Niagara River, creating the first modern power plant although a brilliant scientist, Tesla was not an astute businessman. He created his own obscurity by relinquishing
royalty rights for his inventions to major corporations for the purpose of raising funds for future projects.
Question 1 of 5
What did Tesla accomplish while attending the University of Prague?
Correct Answer: C
Rationale: While attending the University of Prague, Tesla made designs for a brushless alternating current motor. This innovation marked the beginning of his groundbreaking work in the field of electricity and laid the foundation for his future achievements. Tesla's early sketches and ideas for the AC motor at the University of Prague set him on a path that would ultimately revolutionize the way electricity was generated and utilized.

About 6% of the earth is covered by rainforests. The largest rainforest in the world is the
Amazon Basin, which stretches over 2.3 million square miles in nine different South American countries. This area is double the length of all the other remaining rainforests in the world. Brazil contains 60%of the Amazonian rainforest, since it lies at the mouth of the river Amazon. This river is the second largest in the world and contains more than one-fifth oftheworldĆ¢ā‚¬ā„¢sfresh water. The Amazon rainforest is a type of wet broadleaf forest. The weather there is very humid and warm as it rains quite a bit. Because of the high rainfall, the forest is very rich and green. The
tree leaves are pointed and narrow so that the raindrops can easily drop off wet plants. This
tropical rainforest has more living species than the entire European continent. There are over 400 types of insects living in one single rain forest tree for a total of 2.5 million species. One square kilometer of rainforest may contain over 75,000 types of trees and approximately 438,000
different kinds of plants, which comes to a total of 90,000 tons of greenery overall. The Amazon rainforest is home to 2,000 birds and mammals, with one in every five birds in the world living there. Local farmers have lived off this rich and diverse land for thousands of years. They have been able to find food and water here without destroying the land. The Kayapo people of Brazil
farm in an environmentally-friendly way. Instead of chemicals, they use burned wood to enrich the soil, and plant banana trees, which attract wasps. These wasps then feed on leafcutter ants and get rid of these harmful insects. The rainforest also offers a lot of tropical fruits, such as bananas and coconuts, as food.
Cinnamon is made from the bark of a rainforest tree. Amazonian Indians use the fruit and stem
of the Buruti plant as a drink, to make bread and to build houses. Many other plants are used as medicine. But the Amazon rainforest is in very big danger of disappearing. 9,169 square miles of
forest have been cut down in 2003 in Brazil alone. An area of the size of a football field is burned down basically every minute, which means that the rain forest may be gone by the year 2030.The dangers related to this type of activity are obvious. Trees take in poisonous carbon
dioxide from the air and give off oxygen. There is more oxygen and less carbon dioxide around a
rainforest. When trees are cut down, however, the amount of carbon dioxide increases, and the
air gets warmer. This leads to global warming, which is extremely harmful to the environment. It
is estimated that the burning of Brazilian rainforests alone produces 200 million metric tons of carbon dioxide ayear. Another danger connected with destroying the rainforest is the disappearance of plants and animals. When trees are cut down, plants and animals have no more
food left and slowly die out. Killing wild animals is illegal in Brazil, but there is plenty of stealing going on. 38 million animals are stolen and sold illegally each year. The most hunted
animals are birds, especially parrots, followed by snakes and the jaguar.
Question 2 of 5
What does the sentence 'people of Brazil farm in an environmentally friendly way' mean in paragraph 3?
Correct Answer: A
Rationale: The correct answer is A: 'They do not poison the soil when farming.' The statement in the paragraph refers to the environmentally friendly farming practices of the Kayapo people in Brazil. Instead of using harmful chemicals, they opt for burned wood to enrich the soil. This sustainable approach helps maintain the fertility of the land without causing harm to the environment. It highlights their conscious effort to farm in a way that is beneficial and sustainable for the ecosystem, emphasizing the importance of preserving the environment while meeting their agricultural needs.

Question 4 of 5
What is referred to as 'rich and diverse land' at the beginning of paragraph 3?
Correct Answer: B
Rationale: In the text provided, the author mentions that the Amazon rainforest is home to 2,000 birds and mammals, which is an illustration of the rich and diverse ecosystem within the area. This information directly corresponds to the statement about the 'rich and diverse land' at the beginning of paragraph 3. Therefore, the correct answer is option B, as it aligns with the specific details presented in the text.
Extract:
People of Hispanic origin were on the North American continent centuries before settlers arrived
from Europe in the early 1600s and the thirteen colonies joined together to form the United
States in the late 1700s. The first census of the new nation was conducted in 1790, and counted about four million people, most of whom were white. Of the white citizens, more than 80%
traced their ancestry back to England. There were close to 700,000 slaves and about 60,000 "free Negroes". Only a few Native American Indians who paid taxes were included in the census count, but the total Native American population was probably about one million. By 1815, the population of the United States was 8.4 million. Over the next 100 years, the
country took in about 35 million immigrants, with the greatest numbers coming in the late 1800s and early 1900s. In 1882, 40,000 Chinese arrived, and between 1900 and 1907, there were more
than 30,000 Japanese immigrants. But by far, the largest numbers of the new immigrants were
from central, eastern, and southern Europe. An enormous amount of racial and ethnic assimilation has taken place in the United States. In 1908, play-write Israel Zangwill first used the term "melting pot" to describe the concept of a place where many races melted in a crucible and re-formed to populate a new land. Some years during the first two decades of the 20th century, there were as many as one million new
immigrants per year, an astonishing 1 percent of the total population of the United States.
In 1921, however, the country began to limit immigration, and the Immigration Act of 1924
virtually closed the door. The total number of immigrants admitted per year dropped from as many as a million to only 150,000. A quota system was established that specified the number of
immigrants that could come from each country. It heavily favored immigrants from northern and western Europe and severely limited everyone else. This system remained in effect until 1965, although after World War II, several exceptions were made to the quota system to allow in
groups of refugees.
Question 5 of 5
In line 5, the word 'ancestry' is closest in meaning to
Correct Answer: A
Rationale: The word 'ancestry' refers to a person's family or ethnic background, which aligns most closely with the term 'origins'. Ancestry typically denotes the lineage or heritage of individuals, emphasizing where they come from or their roots. 'Inheritance' refers more to the passing down of property or traits, 'color' is unrelated to the context of ancestry, and 'freedom' does not capture the meaning of 'ancestry'. Therefore, 'origins' is the most appropriate term to convey the concept in this context.
