\fbox{\begin{minipage}{\textwidth} Part C: Reading Comprehension Directions: In this part of the test, you will read two passages. Each passage is followed by four questions. Answer the questions by choosing the best choice (1), (2), (3), or (4). Then mark your answer sheet. \end{minipage}}

Passage 1:
For many years people have been trying to create a simple universal language that would serve all over the world as a common means of communication. In the last three hundred years, more than seven hundred such languages have been suggested. The most successful and the most popular of these is a language called Esperanto. It was invented by Ludwig Zamenhof, who lived in Poland. When he was growing up, he saw that people from different backgrounds who lived in Poland had lots of difficulties communicating with each other. This often led to disagreements. Ludwig felt that a common language would help them understand each other better and agree with each other. So he began working on a common international language. He started his work while he was still at school! In 1887, he published some information about his new language. He did not use his real name. He used the name Dr. Esperanto (which means ``one who hopes''). Soon people from all over the world became interested in his language, called Esperanto. Today, Esperanto is spoken by about eight million people throughout the world. Many governments and international organizations recognize it in many ways. Esperanto is often used on radio broadcasts from official government stations.

93- What is the passage mainly about?

1. The life of a Polish school boy
2. Invention of a universal language
3. How Esperanto has helped people
4. How people often do not understand each other

94- What does the word ``these'' in line 4 refer to?
1) Years 2) Means 3) People 4) Languages

95- Which of the following statements is TRUE?

1. Ludwig was afraid of people, so he changed his name.
2. Ludwig started to work on his idea when he was very young.
3. Esperanto has been widely used for the last three hundred years.
4. May people did not understand Ludwig, so they disagreed with him.

96- What do we understand about Ludwig Zamenhof?

1. He was hopeful that his invention would become successful one day.
2. He had difficulty communicating with people when he was growing up.
3. He spoke to eight million people in Esperanto.
4. He worked at an official radio station.

%% Page 17 Passage 2:
Weather describes conditions, such as rain, wind, and sunshine, that occur during a short period of time in a particular place; climate is the overall pattern of weather in a region. From one moment to the next the weather can change. A warm, sunny day can be overtaken by a violent storm. Dark clouds form, high winds blow, and rain lashes the ground, yet it may be only a few minutes before the sunny weather returns. However, in some parts of the world, such as in parts of the tropics, the weather barely changes for months at a time. There it is always hot and heavy rains fall. Meteorologists are scientists who measure and forecast the weather. They do this by studying clouds, winds, and the temperature and pressure of Earth's atmosphere. But despite the use of satellites, computers, and other technology in weather forecasting, weather remains a force of nature that is hard to predict. Several thousand weather stations on land, ships, and aircraft measure weather conditions around the world. The stations contain instruments that record temperature, rainfall, the speed and direction of wind, air pressure, and humidity (the amount of water vapor in the air). Balloons called radiosondes carry instruments to take measurements high in the air. Weather satellites in space send back pictures of the clouds.

1. [97-] Which of the following is TRUE about the difference between weather and climate?
   1. [1)] Weather refers to predictable atmospheric conditions.
   2. [2)] Climate refers to conditions such as rain and wind.
   3. [3)] Weather is a fixed climatic pattern in a region.
   4. [4)] Climate refers to a more constant condition.
   
   
2. [98-] According to the passage, which of the following do meteorologists NOT do when forecasting weather?
   1. [1)] They study clouds.
   2. [2)] They study winds.
   3. [3)] They go high in the air in special balloons.
   4. [4)] They examine the pressure of Earth's atmosphere.
   
   
3. [99-] What does the word ``barely'' in line 6 mean?
   1) Never 2) Often 3) Seldom 4) Occasionally
   
4. [100-] Which of the following is NOT true?
   1. [1)] Weather stations are not built on land only.
   2. [2)] Weather stations contain highly advanced equipment.
   3. [3)] Radiosondes are balloons that take certain tools high in the air.
   4. [4)] Computers and satellites make it possible to predict weather without any difficulty.
