True/False/Not Given Mock Tests

Passage excerpt: "Cryptocurrency, introduced to the world in 2009 with the launch of Bitcoin, has fundamentally challenged traditional notions of money and finance. Unlike government-issued currencies, cryptocurrencies operate on decentralized networks based on blockchain technology — a distributed ledger maintained by thousands of computers worldwide. This decentralization means no single authority, such as a central bank, controls the supply or regulates transactions. Proponents argue that cryptocurrency promotes financial inclusion, reduces transaction costs, and protects against inflation by limiting supply. Critics, however, point to its extreme price volatility, use in illegal activities, and enormous energy consumption, particularly in Bitcoin mining, which some estimates suggest consumes as much electricity as a medium-sized country." According to the passage, all cryptocurrencies are controlled by central banks.

Passage excerpt: "The concept of 'plasticity' in the brain refers to the brain's ability to reorganize itself by forming new neural connections throughout life. For decades, scientists believed that the brain developed fully by early adulthood and could not change significantly afterward. However, research in the late 20th century demonstrated that the adult brain remains plastic and adaptable. 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 memory, than the average person. This structural difference is believed to result from years of navigating complex routes, a process known as 'The Knowledge'." What was found about London taxi drivers' brains? a) They have a smaller hippocampus than the average person. b) They have a larger hippocampus than the average person. c) They have a higher overall brain weight than the average person. d) They show no significant difference in brain structure compared to the average person.

Passage excerpt: "The theory of plate tectonics explains that the Earth's outer shell, known as the lithosphere, is divided into several large plates that float on the semi-fluid asthenosphere beneath. These plates are in constant motion, driven by convection currents in the Earth's mantle. When plates move apart at divergent boundaries, new crust is formed as magma rises to the surface, creating mid-ocean ridges. When plates collide at convergent boundaries, one plate may be forced beneath another in a process called subduction, forming mountain ranges or deep ocean trenches. The movement of these plates is responsible for earthquakes, volcanic eruptions, and the formation of continents." What happens at divergent boundaries? a) One plate is forced beneath another, forming deep ocean trenches. b) New crust is formed as magma rises to the surface, creating mid-ocean ridges. c) Continents drift apart without any geological activity. d) Earthquakes and volcanic eruptions stop occurring.

Passage excerpt: "The concept of biomimicry, which involves designing human systems by emulating nature's time-tested patterns and strategies, has gained significant momentum in recent decades. Nature, through 3.8 billion years of evolution, has developed highly efficient solutions to many of the challenges humans face today. For example, the structure of lotus leaves, which repel water and self-clean, inspired the development of stain-resistant fabrics and self-cleaning paints. Similarly, the streamlined body of a peregrine falcon influenced the design of high-speed train noses in Japan, reducing noise and energy consumption by 20 percent." How did the design of Japanese high-speed trains benefit from studying the peregrine falcon? a) It allowed the trains to carry more passengers. b) It reduced noise and energy consumption by 20 percent. c) It enabled the trains to operate in underwater tunnels. d) It made the trains lighter by using feather-like materials.

Passage excerpt: "The Renaissance, a period of great cultural and intellectual transformation in Europe, began in Italy in the 14th century and spread across the continent over the next two centuries. The word 'Renaissance' means 'rebirth' and refers to the renewed interest in the classical learning and values of ancient Greece and Rome. Key figures of the Renaissance include Leonardo da Vinci, Michelangelo, and Raphael in the arts, and Nicolaus Copernicus and Galileo Galilei in science. The invention of the printing press facilitated the spread of Renaissance ideas, as books and pamphlets could now be produced more quickly and cheaply. The Renaissance ended with the onset of the Protestant Reformation and the Thirty Years' War in the 17th century." What does the word 'Renaissance' mean? a) Revolution b) Rebirth c) Renaissance d) Restoration

Passage excerpt: "The rise of antibiotic-resistant bacteria represents one of the most pressing threats to global public health. The World Health Organization estimates that antibiotic resistance causes at least 700,000 deaths annually worldwide, a figure that could rise to 10 million per year by 2050 if current trends continue. Overprescription of antibiotics in both human medicine and agriculture has accelerated the evolution of resistant strains. Bacteria develop resistance through genetic mutations or by acquiring resistance genes from other bacteria via horizontal gene transfer. One particularly concerning development is the emergence of pan-resistant bacteria — strains immune to all known antibiotics. In 2019, a case was reported in a patient in the United States infected with a bacterium resistant to all 26 classes of antibiotics available at that time. Researchers are racing to develop alternative treatments, including bacteriophage therapy, which uses viruses that naturally infect and kill bacteria, and antimicrobial peptides, which are short protein sequences that can disrupt bacterial cell membranes." According to the passage, bacteriophage therapy uses bacteria to kill viruses. a) TRUE b) FALSE c) NOT GIVEN d) TRUE AND FALSE

Passage excerpt: "The theory of island biogeography, developed by Robert MacArthur and E.O. Wilson in 1967, explains how the number of species on an island is determined by a balance between immigration and extinction rates. Larger islands tend to have more species than smaller ones because they offer more diverse habitats and resources, which reduce extinction rates. Islands closer to the mainland tend to have more species because they are easier for organisms to reach, increasing immigration rates. This theory has had profound implications for conservation biology, particularly in the design of nature reserves, which should ideally be large and connected to other protected areas." According to the theory of island biogeography, why do larger islands tend to have more species? a) Because they are closer to the mainland. b) Because they have more diverse habitats and resources, which reduce extinction rates. c) Because they receive more rainfall than smaller islands. d) Because species on larger islands evolve faster than on smaller islands.

Passage excerpt: "The concept of cultural heritage encompasses both tangible and intangible assets that are passed down from previous generations. Tangible heritage includes physical artifacts, buildings, monuments, and landscapes, while intangible heritage includes traditions, oral expressions, performing arts, and social customs. UNESCO, the United Nations Educational, Scientific and Cultural Organization, maintains a World Heritage List that identifies sites of outstanding universal value. As of 2023, the list includes 1,154 sites across 167 countries, including the Great Wall of China, the Pyramids of Giza, and the Amazon Rainforest. Protecting cultural heritage is important because it provides a link to the past, fosters cultural diversity, and promotes understanding between different peoples." What does intangible cultural heritage include? a) Physical artifacts, buildings, monuments, and landscapes. b) Traditions, oral expressions, performing arts, and social customs. c) Museums, libraries, and archives. d) Natural landscapes and wildlife reserves.
