• Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions:

  Esperanto is what is called a planned, or artificial language. It was created more than a century ago by Polish eye doctor Ludwik Lazar Zamenhof. Zamenhof believed that a common language would help to alleviate some of the misunderstandings among cultures.

  In Zamenhof’s first attempt at a universal language, he tried to create a language that was as uncomplicated as possible. This first language included words such as ab, ac, eb, be and ce. This did not result in a workable language in that these monosyllabic, though short, were not easy to understand or to retain.

  Next, Zamenhof tried a different way of constructing a simplified language. He made the words in his language sound like words that people already knew, but he simplified the grammar tremendously. One example of how he simplified the language can be seen in the suffixes: all nouns in this language end in -o, as in the noun amiko, which means “friend”, and all adjectives end in -a, as in the adjective bela, which means “pretty". Another example of the simplified language can be seen in the prefix mal-, which makes a word opposite in meaning, the word malamiko therefore means “enemy”, and the word malbela therefore means “ugly” in Zamenhof’s language.

  In 1887, Zamenhof wrote a description of this language and published it. He used a pen name, Dr. Esperanto, when signing the book. He selected the name Esperanto because this word means “a person who hopes” in his language. Esperanto clubs began popping up throughout Europe, and by 1950, Esperanto had spread from Europe to America and Asia.

  In 1905, the First World Congress of Esperanto took place in France, with approximately 700 attendees from 20 different countries. Congresses were held annually for nine years, and 4,000 attendees were registered for the Tenth World Esperanto Congress scheduled for 1914, when World War I erupted and forced its cancellation.

  Esperanto has had its ups and downs in the period since World War I. Today, years after it was introduced, it is estimated that perhaps a quarter of a million people are fluent in it. This may seem like a large number, but it is really quite small when compared with the billion English speakers and billion Mandarin Chinese speakers in today’s world. Current advocates would like to see its use grow considerably and are taking steps to try to make this happen.

  Question:The passage would most likely be assigned reading in a course on ________.

• Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions:

  Although people drive in all countries, the rules can be quite different between nations and areas. For this reason, you should always learn the laws before you decide to drive in a foreign country. If you are not careful, you can get into trouble since the rules might be very different from what you are used to. For example, you can find some big differences in laws related to the minimum driving age, the appropriate side of the road to drive on, and mobile phone use while driving. In the U.S., people who live in Alaska may obtain a learner’s permit [legal permission to drive while being supervised] at the age of fourteen. This is quite different from the driving laws of Niger, where a person must be at least twenty-three years old to drive. If you are inquisitive to know the minimum driving age in most countries, the answer is eighteen. It may also surprise you to learn that not every country allows its citizens to drive, although most of them do. For example, women are not allowed to drive in Saudi Arabia no matter how old they are. Instead, they must have a male family member or hired male driver to travel by car. Driving on the right or left side of the road also varies. For instance, in Great Britain, Cyprus, Australia, India, and Malaysia people drive on the left. However, in the U.S., Mexico, France, and Canada people are required to drive on the right. As a matter of fact, one country can have different driving rules for different areas. People in Hong Kong drive on the left, while drivers in other parts of China use the right side of the road. Other driving laws that are different between countries include thoserelated to using mobile phones. In Japan, using any kind of mobile phone device is illegal, even if you do not need to hold the phone with your hands. However, in Argentina and Australia, drivers are allowed to talk on their mobile phones as long as they do not use their hands. You might also find it interesting to learn that some countries have very unusual laws. For example, in the country of Cyprus, it is against the law to eat or drink anything while driving. Even more interesting is that in Germany, there is a famous road called the Autobahn, where certain parts have no speed limit at all!
