Surrealism was a movement in graphic art and literature that was founded in Paris, in 1924, by Andr Breton. Inspired by another movement in art called Dadaism, the Surrealist movement has been one of the most influential art movements in the 20th century. It eventually 5 had a worldwide audience, flourishing notably in the United States during World War II. Surrealism focused on the role of the unconscious in the creative process.

Surrealist writers, such as Aragon and Soupalt, believed in directly transcribing onto paper anything their 10 unconscious mind wished them to. They never altered or revised what they wrote because that would have interfered with the purity of their creation. Surrealist painters, a group that included such famous names as Miro, Dali, and Ernst, displayed a wide variety of style and content. Though Breton was the founder of this movement, his 15 strong leadership style brought about dissent, which resulted in several of the painters officially breaking away from the movement.

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.

A pilot cannot fly a plane by sight alone. In many conditions, such as flying at night and landing in dense fog, a pilot must use radar, an alternative way of navigating. Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot 5 how fast nearby planes are moving.
The basic principle of radar is exemplified by what happens when one shouts in a cave. The echo of the sounds against the walls helps a person determine the size of the cave. With radar, however, the 10 waves are radio waves instead of sound waves. Radio waves travel at the speed of light, about 300,000 kilometers in one second. A radar set sends out a short burst of radiation waves. Then it receives the echoes produced when the waves bounce off objects. By determining the time it takes for the echoes to return to the radar set, a trained 15 technician can determine the distance between the radar set and other objects. The word "radar," in fact, gets its name from the term "radio detection and ranging." "Ranging" is the term for detection of the distance between an object and the radar set. Besides being of critical importance to pilots, radar is essential for air traffic control, 20 tracking ships at sea, and for tracking weather systems and storms.

1. What is the main topic of this passage?
(A) the nature of radar
(B) types of ranging
(C) alternatives to radar
(D) history of radar
2. In line 2, the word "dense" could be replaced by
(A) cold
(B) wet
(C) dark
(D) thick
3. According to the passage, what can radar detect besides location of objects?
(A) size
(B) weight
(C) speed
(D) shape
4. The word "shouts" in line 8 is most similar in meaning to which of the following?
(A) eavesdrops
(B) yells
(C) confesses
(D) whispers
5. Which of the following words best describes the tone of this passage?
(A) argumentative
(B) imaginative
(C) explanatory
(D) humorous
6. The phrase "a burst" in line 13 is closest in meaning in which of the following?
(A) an attachment
(B) a discharge
(C) a stream
(D) a ray
7. The word "it" in line 13 refers to which of the following?

(A) sound
(B) heat
(C) radio
(D) light
10. The word "tracking" in line 20 is closest in meaning to which of the following?
(A) repairing
(B) searching for
(C) glancing at
(D) fighting
11. Which of the following would most likely be the topic of the next paragraph?
(A) other uses of radar
(B) uses of sonar technology
(C) other technology used by pilots
(D) a history of flying
12. What might be inferred about radar?

Read the passage and answer the following questions: Carbohydrates, which are sugars, are an essential part of a healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose to complex sugars such as amylose and 5 amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person's diet. This translates to about 75-100 grams of carbohydrates...

Carbohydrates range from simple sugars like glucose to complex sugars such as amylose and 5 amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person's diet. This translates to about 75-100 grams of carbohydrates per day.
A diet that is deficient in carbohydrates can have an adverse effect 10 on a person's health. When the body lacks a sufficient amount of carbohydrates it must then use its protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a build-up of ketones 15 in the body that causes fatigue, lethargy, and bad breath. 1. What is the main idea of this passage?
(A) Carbohydrates are needed for good health.
(B) Carbohydrates prevent a build-up of proteins.
(C) Carbohydrates can lead to ketosis.
(D) Carbohydrates are an expendable part of a good diet.
2. The word "function" as used in line 3 refers to which of the following?
(A) neglect
(B) serve
(C) dissolve
(D) profess
3. The word "range" as used in line 3 is closest in meaning to which of the following?
(A) probe
(B) proceed
(C) hail
(D) extend
4. In line 5, the word "estimate" could best be replaced by
(A) disbelieve
(B) declare
(C) calculate
(D) wonder
5. According to the passage, what do most nutritionists suggest?
(A) Sufficient carbohydrates will prevent gluconeogenesis.
(B) Carbohydrates are simple sugars called glucose.
(C) Carbohydrates should make up about a quarter of a person's daily diet.
(D) Carbohydrates should be eaten in very small quantities.
6. Which of the following do carbohydrates NOT do?
(A) prevent ketosis
(B) cause gluconeogenesis
(C) provide energy for the body
(D) flavor and sweeten food
7. Which of the following words could best replace "deficient" as used in line 9?
(A) outstanding
(B) abundant
(C) insufficient
(D) unequal
8. What does the word "this" refer to in line 13?
(A) using protein supplies for energy
(B) converting carbohydrates to energy
(C) having a deficiency in carbohydrates
(D) having an insufficient amount of protein
9. According to the passage, which of the following does NOT describe carbohydrates?
(A) a protein supply
(B) a necessity
(C) a range of sugars
(D) an energy source
10. The word "lack" in line 13 is most similar to which of the following?
(A) plethora
(B) shortage
(C) derivation
(D) commission
11. Which of the following best describes the author's tone?
(A) sensitive
(B) emotional
(C) informative
(D) regretful
12. Which of the following best describes the organization of this passage?
