Passage excerpt: "Volcanic eruptions can have both warming and cooling effects on the global climate. When a volcano erupts, it releases vast amounts of carbon dioxide, a greenhouse gas that contributes to warming. However, eruptions also inject sulfur dioxide into the stratosphere, where it forms sulfate aerosols that reflect sunlight back into space. This cooling effect can last for several years and may temporarily offset the warming caused by carbon emissions. The 1991 eruption of Mount Pinatubo in the Philippines lowered global temperatures by approximately 0.5°C for about 18 months." The cooling effect of volcanic eruptions lasts longer than the warming effect. a) TRUE b) FALSE c) NOT GIVEN

Passage excerpt: "Neuroplasticity, the brain's ability to reorganize itself by forming new neural connections throughout life, has transformed our understanding of brain development. For decades, scientists believed that the human brain was largely fixed after childhood, with limited capacity for change. However, research using advanced imaging techniques has shown that the brain continuously rewires itself in response to learning, experience, and injury. For example, London taxi drivers, who must memorize thousands of streets and routes, have been found to have a larger hippocampus — the brain region associated with spatial navigation — than the general population. Similarly, stroke patients can retrain unaffected brain regions to take over functions lost due to damage, a principle that underpins modern rehabilitation therapy." What brain region was found to be larger in London taxi drivers?

Passage excerpt: "Sound travels as mechanical waves through a medium such as air, water, or solids. The speed of sound varies depending on the medium: it travels fastest in solids, slower in liquids, and slowest in gases. In air at room temperature, sound travels at approximately 343 meters per second. The pitch of a sound is determined by its frequency, measured in Hertz (Hz), while the loudness is determined by its amplitude. Humans can typically hear sounds with frequencies between 20 Hz and 20,000 Hz. Sounds below 20 Hz are called infrasound, and those above 20,000 Hz are called ultrasound, which is used in medical imaging and sonar technology." Complete the notes below. | Properties of sound | |---| | Sound travels fastest in ______, slowest in gases | | Speed in air at room temperature: approximately ______ meters per second | | Pitch is determined by ______; loudness by ______ | | Human hearing range: 20 Hz to ______ Hz | a) liquids — 343 — amplitude — frequency — 10,000 b) solids — 343 — frequency — amplitude — 20,000 c) solids — 243 — frequency — amplitude — 20,000 d) gases — 343 — frequency — amplitude — 20,000

Passage excerpt: "The 2008 global financial crisis revealed deep vulnerabilities in the worldwide banking system. Many financial institutions had become heavily invested in mortgage-backed securities, complex financial products created by pooling together large numbers of home loans. When housing prices declined and borrowers began defaulting on their mortgages, the value of these securities plummeted. The crisis was exacerbated by the fact that many banks were highly leveraged, meaning they had borrowed substantial amounts to amplify their investments. When losses mounted, several major institutions collapsed or required government bailouts, triggering a worldwide economic recession that resulted in millions of job losses." The 2008 financial crisis originated primarily in the United States housing market. a) TRUE b) FALSE c) NOT GIVEN d) PARTIALLY TRUE

Passage excerpt: "The invention of the printing press by Johannes Gutenberg around 1440 revolutionized the spread of knowledge in Europe. Before the printing press, books were copied by hand, a process that was slow, expensive, and prone to errors. The printing press made it possible to produce books quickly and at a fraction of the cost, leading to an unprecedented increase in literacy rates and the democratization of knowledge. This technological breakthrough played a crucial role in the Renaissance, the Reformation, and the Scientific Revolution, as ideas could now be shared across vast distances with remarkable speed and accuracy." The word "democratization" in the passage is closest in meaning to: a) The destruction of traditional knowledge systems b) The making of knowledge accessible to a wider audience c) The standardization of religious texts d) The government control of information

Passage excerpt: "Language extinction is a growing concern among linguists. Estimates suggest that of the approximately 7,000 languages spoken today, between 3,000 and 4,000 may disappear by the end of this century. Languages tend to become endangered when dominant cultures exert pressure on minority speakers to adopt the majority language for economic and social advancement. Dr. Keiko Takahashi has documented the decline of indigenous languages in Japan, particularly the Ainu language, which has fewer than 10 fluent speakers remaining. Meanwhile, Dr. Carlos Mendez has worked with indigenous communities in South America to develop bilingual education programs that teach both the native language and the national language, showing promising results in language preservation." Match the researchers to their work. a) Keiko Takahashi — bilingual education programs in South America b) Carlos Mendez — Ainu language documentation in Japan c) Keiko Takahashi — Ainu language decline in Japan d) Carlos Mendez — language extinction in Europe

Read the following paragraph: "The printing press, invented by Johannes Gutenberg around 1440, fundamentally transformed European society. Before its invention, books were hand-copied by monks and were extremely expensive, limiting literacy to the clergy and nobility. The printing press reduced the cost of books by approximately 80%, making them accessible to merchants, artisans, and eventually the broader population. This democratization of knowledge contributed directly to the Renaissance, the Reformation, and the Scientific Revolution. Martin Luther's 95 Theses, posted in 1517, were printed and distributed across Germany within weeks — an outcome that would have been impossible in the hand-copying era." Which heading best describes the paragraph? a) The Life and Work of Johannes Gutenberg b) How the Printing Press Transformed European Society c) The Relationship Between the Renaissance and the Reformation d) Why Books Were Expensive Before the 15th Century

Passage excerpt: "Some critics argue that standardized testing creates an overly rigid educational environment that stifles creativity. However, proponents contend that standardized tests provide an objective measure of student performance and help identify students who need additional support. The debate continues, with some countries reforming their testing systems while others maintaining the status quo." The writer believes that standardized testing is entirely beneficial. a) YES b) NO c) NOT GIVEN
