Passage excerpt: "The concept of ecological succession describes how ecosystems change and develop over time. When a volcanic eruption destroys an existing ecosystem, primary succession begins — lichens and mosses colonize bare rock, gradually creating soil that allows grasses, shrubs, and eventually trees to establish. In contrast, secondary succession occurs after a disturbance such as a forest fire or hurricane, where soil already exists and recovery is faster. Secondary succession can restore a forest in 50 to 100 years, while primary succession may take thousands of years. Climate change is now altering both processes, with shifting temperature and precipitation patterns creating conditions that some species cannot adapt to quickly enough." Complete the sentence: Primary succession takes ______ than secondary succession because ______. a) longer — soil must be created from bare rock b) shorter — lichens grow more slowly than grasses c) longer — volcanic eruptions destroy all life d) shorter — secondary succession starts after fires

Passage excerpt: "Deforestation in the Amazon rainforest has reached critical levels, with approximately 17% of the original forest already lost. The loss of trees not only destroys habitat for countless species but also reduces the forest's capacity to absorb carbon dioxide, accelerating climate change. Local communities are affected in multiple ways: indigenous peoples lose their traditional lands, while farmers face changing rainfall patterns that make agriculture increasingly difficult. The Brazilian government has implemented various programs to combat deforestation, including the Creation of Protected Areas and the Monitoring of the Amazon using satellite technology. Between 2004 and 2012, deforestation rates decreased by 80%, but they increased again after 2013." Complete the notes below. Choose ONE word only from the passage for each answer. Notes: Amazon deforestation - Approximately ______ of the original forest has been lost. - Deforestation reduces the forest's ability to absorb ______. - Indigenous peoples lose their ______ lands. - Deforestation rates decreased by ______ between 2004 and 2012. a) 17% — carbon dioxide — traditional — 80% b) 20% — oxygen — ancestral — 75% c) 15% — greenhouse gases — historical — 85% d) 25% — carbon — native — 90%

Passage excerpt: "The rise of antibiotic resistance has become one of the most pressing public health challenges of the modern era. Bacteria evolve resistance through natural selection: when antibiotics kill susceptible bacteria, the resistant mutants survive and multiply. The overprescription of antibiotics in human medicine and their widespread use in agricultural livestock have accelerated this evolutionary process. Some experts argue that the pipeline for new antibiotic development has dried up because pharmaceutical companies find it less profitable to develop antibiotics compared to drugs for chronic conditions, which generate recurring revenue. The World Health Organization has called for a global action plan, including better infection prevention, increased investment in new treatments, and improved diagnostic tools to reduce unnecessary antibiotic use." The writer believes that the overuse of antibiotics in agriculture is a minor contributor to antibiotic resistance.

Passage excerpt: "The phenomenon of urban heat islands occurs when cities experience significantly higher temperatures than surrounding rural areas. This temperature difference is caused by the replacement of natural land cover with concrete, asphalt, and buildings, which absorb and retain more heat. Urban heat islands can increase energy consumption, air pollution, and heat-related illness and death. Cities around the world are responding with strategies such as planting urban trees, creating green roofs, and using reflective building materials to mitigate the effects of urban heat islands." The word "mitigate" in the passage is closest in meaning to: a) Accelerate b) Worsen c) Alleviate d) Measure

Passage excerpt: "The Renaissance, a period of cultural and intellectual rebirth, began in Italy in the fourteenth century and spread across Europe over the next two centuries. It was characterized by a renewed interest in classical Greek and Roman learning, which had been largely preserved by Islamic scholars during the European Middle Ages. Italian city-states such as Florence, Venice, and Rome became centers of artistic and intellectual achievement, supported by wealthy patrons like the Medici family. The Renaissance produced some of history's greatest artists, scientists, and writers, including Leonardo da Vinci, Michelangelo, and William Shakespeare. The invention of the printing press facilitated the spread of Renaissance ideas throughout Europe, accelerating the cultural transformation." The Renaissance began in France and later spread to Italy. a) TRUE b) FALSE c) NOT GIVEN d) TRUE BUT UNCERTAIN

Passage excerpt: "Quantum mechanics is a branch of physics that describes the behaviour of matter and energy at the smallest scales — atoms and subatomic particles. One of the most counterintuitive aspects of quantum mechanics is wave-particle duality, the concept that every particle exhibits both wave-like and particle-like properties. For example, light can behave as a wave (demonstrating interference and diffraction) and as a particle (the photoelectric effect, where light knocks electrons off a metal surface). Another key principle is the Heisenberg Uncertainty Principle, which states that it is impossible to simultaneously know both the exact position and the exact momentum of a particle. The more precisely one property is measured, the less precisely the other can be known. Quantum entanglement, described by Einstein as "spooky action at a distance," occurs when two particles become linked so that the state of one instantly affects the other, regardless of the distance between them." Do the following statements agree with the claims of the writer? 1. Quantum mechanics deals only with the behaviour of light. 2. Wave-particle duality means particles can show both wave and particle characteristics. 3. The Heisenberg Uncertainty Principle is caused by limitations in measurement instruments. a) False — True — Not Given b) True — True — False c) False — False — Not Given d) True — True — True

Passage excerpt: "The rise of social media has fundamentally transformed how people consume and share news. A 2023 study by the Pew Research Center found that 66 percent of American adults get their news at least sometimes from social media platforms, with younger demographics showing even higher rates. This shift has raised concerns about the spread of misinformation, as social media algorithms prioritize content that generates engagement rather than content that is accurate or important. Unlike traditional journalism, which typically involves editorial oversight and fact-checking, social media content can be posted by anyone without verification. However, some argue that social media has also democratized news reporting by giving a voice to citizen journalists and marginalized communities that are often overlooked by mainstream media." What concern has been raised about social media's role in news dissemination? a) Social media platforms charge too much for users to access news. b) Social media algorithms prioritize engagement over accuracy or importance, leading to the spread of misinformation. c) Social media has eliminated all forms of traditional journalism. d) Social media prevents citizen journalists from sharing their stories.

Passage excerpt: "The study of animal intelligence has produced some remarkable findings across species. Wolfgang Köhler, a German psychologist, conducted experiments in the 1920s with chimpanzees that demonstrated their ability to solve problems by suddenly rearranging solutions rather than through gradual trial and error — a phenomenon he called 'insight learning.' In more recent research, Dr. Jane Goodall observed chimpanzees in Tanzania using tools to hunt for termites, modifying sticks to remove leaves before insertion. Meanwhile, Dr. Irene Pepperberg's work with an African grey parrot named Alex showed that parrots can understand and use over 100 English words, recognize colors, shapes, and numbers, and comprehend the concept of zero." Match the researchers to their findings. a) Wolfgang Köhler — chimpanzees use and modify tools b) Jane Goodall — insight learning in chimpanzees c) Irene Pepperberg — parrots understand words and concepts including zero d) Jane Goodall — parrots can recognize colors and numbers
