Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 30 to 34
Mickey Mouse, Walt Disney's most famous character, made his screen debut on November 18, 1928, as star of the first sound cartoon, Steamboat Willie. Since his debut, Mickey Mouse has become an international personality whose success laid the financial foundation upon which Walt Disney built his creative organization. Besides being the personification of the Disney Empire, Mickey Mouse has become one of the most universal symbols of the twentieth century.
Mickey Mouse was born in Walt Disney's imagination early in 1928 on a train ride from New York to Los Angeles. Walt was returning with his wife from a business meeting at which his cartoon creation, Oswald the Rabbit, had been wrestled from him by his financial backers. Only 26 at the time and with an active cartoon studio in Hollywood, Walt had gone east to arrange for a new contract and more money to improve the quality of his Oswald pictures. The moneymen declined, and since the character was copyrighted under their name, they took control of it. “So I was all alone and had nothing." Walt recalled later. “Mrs. Disney and I were coming back from New York on the train and I had to have something I could tell them. I'd lost Oswald so, I had this mouse in the back of my head because a mouse is sort of a sympathetic character in spite of the fact that everybody's frightened of mice, including myself". Walt spent the return train ride conjuring up a little mouse in red velvet pants and named him “Mortimer”, but by the time the train screeched into the terminal station in Los Angeles, the new dream mouse had been rechristened. Walt's wife, Lillian, thought the name "Mortimer" was too arrogant and suggested “Mickey". A star was born!
What happened in late 1928?
Mickey Mouse was first seen in a film
Walt Disney built a new empire.
Mickey Mouse was thought up
Steamboat Willie was filmed

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions from 35 to 42
Pollution is a threat to many species on earth, but sometimes it can cause species to thrive. Such is the case with Pfiesteria piscicida. A one-celled creature called a dinoflagellate, Pfiesteria inhabits warm coastal areas and river mouths, especially along the eastern United States. Although scientists have found evidence of Priesteria in 3,000-year-old sea floor sediments and dinoflagellates are thought to be one of the oldest life forms on earth, few people took notice of Pfiesteria.
Lately, however, blooms - or huge, dense populations - of Pfiesteria are appearing in coastal waters, and in such large concentrations the dinoflagellates become ruthless killers. The blooms emit powerful toxins that weaken and entrap fish that swim into the area. The toxins eventually cause the fish to develop large bleeding sores through which the tiny creatures attack, feasting on blood and flesh. Often the damage is astounding. During a 1991 fish kill that was blamed on Pfiesteria on North Carolina's Neusc River, ncarly one billion fish died and bulldozers had to be brought in to clear the remains from the river. Of course, such events can have a devastating effect on commercially important fish, but that is just one way that Pfiesteria causes problems. The toxins it emits affect human skin in much the same way as they affect fish skin. Additionally, fisherman and others who have spent time near Pfiesteria blooms report that the toxins seem to get into the air, where once inhaled they affect the nervous system, causing severe headaches, blurred vision, nausea, breathing difficulty, short-term memory loss and even cognitive impairment.
For a while, it seemed that deadly Pfiesteria blooms were a threat only to North Carolina waters, but the problem seems to be spreading. More and more, conditions along the east coast seem to be favorable for Pfiesteria. Researchers suspect that pollutants such as animal waste from livestock operations, fertilizers washed from farmlands and waste water from mining operations have probably all combined to promote the growth of Pfiesteria in coastal waters.
What is true of Pfiesteria?
It has been a menace to fish and humans for over 3,000 years
It seems to flourish in the presence of certain pollutants
In large concentrations, it poses a threat to fish but not to humans
It is the oldest life form on earth

What is the main function of the toxins emitted by the dinoflagellates?
They weaken the fish just long enough for the tiny creatures to attack
They cause fish to develop wounds on which the creatures feed
They damage the nervous system of potential predators
They are quick-acting poisons that kill fish within minutes

For a while, it seemed that deadly Pfiesteria blooms were a threat only to North Carolina waters, but the problem seems to be spreading. More and more, conditions along the east coast seem to be favorable for Pfiesteria. Researchers suspect that pollutants such as animal waste from livestock operations, fertilizers washed from farmlands and waste water from mining operations have probably all combined to promote the growth of Pfiesteria in coastal waters.
What is especially worrying about Pfiesteria blooms?
Conditions are becoming increasingly favorable for their spread
Researchers have no idea as to exactly what causes them
They have devastated the fishing industry in U.S. coastal waters
They are fatal to humans who come in contact with them
Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions from 35 to 42
Pollution is a threat to many species on earth, but sometimes it can cause species to thrive. Such is the case with Pfiesteria piscicida. A one-celled creature called a dinoflagellate, Pfiesteria inhabits warm coastal areas and river mouths, especially along the eastern United States. Although scientists have found evidence of Priesteria in 3,000-year-old sea floor sediments and dinoflagellates are thought to be one of the oldest life forms on earth, few people took notice of Pfiesteria.
Lately, however, blooms - or huge, dense populations - of Pfiesteria are appearing in coastal waters, and in such large concentrations the dinoflagellates become ruthless killers. The blooms emit powerful toxins that weaken and entrap fish that swim into the area. The toxins eventually cause the fish to develop large bleeding sores through which the tiny creatures attack, feasting on blood and flesh. Often the damage is astounding. During a 1991 fish kill that was blamed on Pfiesteria on North Carolina's Neusc River, ncarly one billion fish died and bulldozers had to be brought in to clear the remains from the river. Of course, such events can have a devastating effect on commercially important fish, but that is just one way that Pfiesteria causes problems. The toxins it emits affect human skin in much the same way as they affect fish skin. Additionally, fisherman and others who have spent time near Pfiesteria blooms report that the toxins seem to get into the air, where once inhaled they affect the nervous system, causing severe headaches, blurred vision, nausea, breathing difficulty, short-term memory loss and even cognitive impairment.

All of the following are true, according to the passage, EXCEPT ___________
the toxic substances emitted by Pfiesteria have a similar effect on human and fish skins
animal and chemical waste from farmlands, livestock and mining operations may contribute to the expansion of Pfiesteria
Pfiesteria was not commonly noticed despite scientific findings
Pfiesteria caused the death of about one billion fish in the late 1990s
