In every healthy democracy one will find, in addition to lively discussion and a thriving press, lots of political satire. Political satire is a genre of written, oral, and graphic communication that pokes fun at politicians, political parties, and the activities of government. It is humor, but humor with a purpose; by exaggerating faults and foibles, the satirist hopes to provoke laughter while making a point. Leaders of governments and political parties often suffer most at the hands of the satirist, so it is wise for those who wish to make a career of politics to be able to laugh at themselves and take a joke. Like a forest without the sounds of birds, a democracy without the sights and sounds of political satire is a sign that something is amiss.
The author's main purpose in writing the passage is most likely to
describe the different kinds of political satire.
explain what political satire is and why it is important.
criticize the use of political satire in a democratic political culture.
argue that there is something wrong with our democratic political culture.
explain what political satire is and why it is important.
International Falls, Minnesota, a city on the U.S. and Canadian border, earned the legal right to call itself the "Icebox of the Nation" after battling the ski town of Fraser, Colorado, for the title. After learning that Fraser had been using the slogan, which their own town had claimed since 1948, International Falls officials headed for the U.S. Patent and Trademark Office and successfully obtained a registration certificate. The legal victory is about more than simple bragging rights. International Falls uses the icebox moniker to market itself as the country's best location for cold-weather testing projects.
The passage implies that the "Icebox of the Nation" slogan
brings both dollars and recognition to International Falls.
was rightfully awarded to the city with the colder weather.

The American newspaper columnist Art Buchwald wrote humor columns--first for the European edition of the New York Herald Tribune in the 1950s and later for the Washington Post. Rather than the stinging wit of some of his contemporaries, Buchwald's style was kindly. Every once in a while, however, his patience with a politician, institution, or policy would wear thin, and his readers would see another, less avuncular side. Art Buchwald's newspaper column was awarded a Pulitzer Prize for commentary in 1982.
Over the course of his career he would write newspaper columns and publish humorous books for half a century.
One can infer from the passage that Art Buchwald's writing, when he nearly lost his patience, was
biting.

The accumulation of tiny genetic changes could account for the vast differences between humans and chimpanzees, researchers recently reported.
They found that less than 1.5 percent of the DNA found on chromosome 22 in humans differs from the DNA on the equivalent chromosome in chimps.
But these small variations are far from the whole story. Eight-three percent of chimpanzee chromosome 22 proteins are different from their human counterparts. This means that only 17 percent of the chromosome 22 genes are identical, indicating that the evolutionary gulf between humans and chimps is much wider than the 98.5 percent match their DNA might appear to indicate.
According to the paragraph, human beings
have evolved to use genes instead of the proteins chimpanzees use.
are identical to chimps except that they are 83 percent more evolved.
are less alike than the 1.5 percent difference their DNA suggests.
have 17 of the same genes as chimps, but 83 different ones.
are less alike than the 1.5 percent difference their DNA suggests.
Canada is politically complex. Like the United Kingdom, on the other side of the Atlantic Ocean, Canada is a parliamentary democracy that is also a constitutional monarchy. In fact, the two countries share the same monarch.
How does this work? The short answer is that there is a distinction made between running the government and being the head of state. The Canadian parliament and its prime minister, like the two houses of Congress and the president of the United States, respectively, run the government. It is they who make the laws and decide how revenues are spent. However, in the United States, the president acts as both the head of government and the head of state. In Canada, those roles are split between two different people.
The monarch either a king or queen acts as the official head of state. This division of labor has the advantage of helping to make the head of state in Canada a non-political symbol of the country and focus of patriotic feelings like the role the U.S. flag plays for most people in the United States.
According to the passage, the president of the United States is most like a combination of the Canadian
prime minister and monarch

In 2010, Los Angeles, a huge city whose residents are dependent mainly on automobiles for transportation, boasted a state-of-the-art traffic control system. Sensors embedded in the city's roads sent data on millions of cars to a traffic control center that used this information to control the timing of traffic lights and thus improve traffic flow. This information was also placed on the Internet in real time, where the data informed local traffic reporters and commuters about the best routes to follow through the city. Although a massive amount of data was collected by these sophisticated sensors and computers, the information was purged every few days.
The passage implies which of the following about the Los Angeles traffic control system in 2010?
It eliminated most traffic jams in the city.
It significantly reduced the need for traffic reporters.
The data collected were not being used for city planning purposes.
There were plans to expand it to include freeways as well as streets.
The data collected were not being used for city planning purposes.
To make pancakes, take two eggs and break them, placing the egg whites in a small mixing bowl and the yolks in a large mixing bowl. Turn the mixer on high and beat the egg whites until they form peaks. Add one and one-half cups of buttermilk and two tablespoons of oil to the egg yolks. In a separate bowl, mix together two cups of flour, one-half teaspoon of salt, one-half teaspoon of baking soda, and one-quarter teaspoon of baking powder.
Remove the small bowl from the mixer and replace it with the large bowl.
Turn the mixer onto low speed. Once mixed, add the flour mixture. As soon as the flour mixture barely blends in with the egg yolk mixture, stop. The batter will look extremely lumpy. Take a large serving spoon and fold the stiff egg whites into the batter. This means the egg whites are added and gently "cut" and "turned over" into the mixture. There will be large globs of egg whites in the bowl along with the lumps of flour. Spoon the batter onto the griddle and cook.
According to the passage, the flour mixture is added to the
small bowl containing the oil.

large bowl containing the buttermilk.

Honeybee stings, although briefly painful, are seldom life threatening. If stung, the first thing a person should do is remove the stinger. Doing so quickly can limit the severity of the pain, swelling, or itching common symptoms associated with a sting. When stung by a honeybee, many people panic, which exacerbates their reactions rather than minimizing them. Most people only experience local reactions to honeybee stings, with symptoms such as swelling occurring around the area of the sting. Others experience allergic reactions that can be severe, if not life-threatening. If pain and swelling are accompanied by shortness of breath, dizziness, or a rash, this may indicate an allergic reaction, and prompt medical attention is required.
Not all honeybee stings require the attention of a doctor, but stings should always be addressed quickly and carefully.
Which of the following best expresses the major emphasis of the passage?
Staying calm when stung by a honeybee can prevent an allergic reaction.
Prompt medical attention is required if a person experiences swelling after a sting treatment.
Serious allergic reactions to honeybee stings are rare but require immediate

No one gave a thought to the older worlds of space as sources of human danger, or thought of them only to dismiss the idea of life upon them as impossible or improbable. It is curious to recall some of the mental habits of those departed days. At most terrestrial men fancied there might be other men upon Mars, perhaps inferior to themselves and ready to welcome a missionary enterprise. Yet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this earth with envious eyes, and slowly and surely drew their plans against us. And early in the twentieth century came the great disillusionment.
Which word or phrase is used in the passage to describe extraterrestrial life, according to some humans who pondered its possibility before the twentieth century?
curious
dangerous
ready to welcome
cool and unsympathetic
