Paragraph 1What the author does:The author introduces the issue of endangered languages and explains their cultural importance.
Short summary:Languages contain unique words and expressions that reflect a culture's way of life. However, many languages are disappearing rapidly. Although linguists try to record them, their survival ultimately depends on communities continuing to value and use them.
Paragraph 2What the author does:The author provides a specific example of how mathematics can help preserve an endangered language.
Short summary:Anne Kandler and her colleagues developed a mathematical model of Scottish Gaelic. By using demographic, economic, and cultural data in differential equations, they estimated how many new speakers were needed each year to prevent the language from declining, helping policymakers create preservation strategies.
Paragraph 3What the author does:The author concludes by extending the idea to other endangered languages and emphasizing the broader usefulness of mathematical models.
Short summary:Mathematical models could also help save other endangered languages, such as Quechua, Chinook, and Istrian Vlashki. Studying languages that have survived can provide valuable insights for protecting other languages at risk.
1. The passage is primarily concerned with which of the following?A. Outlining the various idiosyncrasies of some languages and their diversity.
Wrong: The passage mentions unique linguistic features only in the first paragraph as examples. The main focus is not language diversity.
B. Emphasizing the versatility of Mathematics.Wrong: The passage does not discuss the many uses of mathematics. It focuses specifically on its role in language preservation.
C. Discussing the steps to be taken for saving languages.
Wrong: The author does not provide a detailed plan for saving languages; instead, he highlights one useful tool: mathematical models.
D. Describing the importance of languages.
Wrong: The importance of languages is mentioned as background information, not as the central topic.
E. Describing the role of Mathematics in preserving languages.
Correct: The passage mainly explains how mathematical models can help preserve endangered languages.
2. Which of the following best describes the relation of the first paragraph to the passage as a whole?A. It makes a general observation to be exemplified.
Wrong: The first paragraph does not present a general idea that is later illustrated with examples.
B. It outlines a process to be analyzed.
Wrong: No process is described in the first paragraph.
C. It identifies a problem the solution of which is to be discussed.
Correct: The first paragraph introduces the problem of language extinction, and the rest of the passage presents mathematical modeling as a possible solution.
D. It advances an argument to be disputed.
Wrong: The author does not challenge or refute any argument.
E. It introduces conflicting arguments to be reconciled.
Wrong: No opposing viewpoints are presented.
3. The Author’s conclusion that ‘languages such as Quechua, Chinook and Istrian Vlashki can be saved using such mathematical models’ is most weakened if which of the following is found to be true?A. The speakers of these languages perceive them as being inferior to other non-native languages.
Correct: We can understand from the last part of the second paragraph that mathematical model’plan takes off after calculating how important the language is for people. If it’s importan, the plan takes off. Without a language being considered valuable, no plan gets off the groung.
B. The mathematical models used for Gaelic language are simplistic and not applicable to these languages.
Wrong: A new mathematical model could be developed. The Gaelic one cannot be necessarily used, maybe a new one emerges.
C. Statistics of speakers of these languages have not been properly documented.
Wrong: Lack of data makes the analysis harder, but it does not prove that the models are ineffective.
D. Patterns in the numbers of the speakers can only be identified by mathematical research.
Wrong: This actually strengthens the argument for using mathematical models.
E. Linguists have shown very little interest in these languages.
Wrong: The interest of linguists does not directly affect whether the models can work.
