True/False/Not Given Mock Tests

Passage excerpt: "Invasive species are non-native organisms that cause harm to the environment, economy, or human health. They outcompete native species for resources such as food, water, and habitat, often leading to population declines or extinctions. The introduction of invasive species can occur through multiple pathways: intentional release for agriculture or the pet trade, accidental transport in shipping ballast water, and unintentional entry through trade in agricultural goods. The brown tree snake, introduced to Guam in the 1940s, is a notorious example, causing the extinction of most of the island's native forest birds. Economic damages from invasive species in the United States alone are estimated at over 120 billion dollars annually." The passage states that invasive species only cause environmental harm.

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." The passage states that bacteriophage therapy uses bacteria to kill viruses. a) TRUE b) FALSE c) NOT GIVEN d) TRUE AND FALSE

Passage excerpt: "Mitochondria, the powerhouses of the cell, have their own DNA — distinct from the DNA found in the cell nucleus. This mitochondrial DNA (mtDNA) is inherited exclusively from the mother, as sperm mitochondria are destroyed after fertilization. The maternal inheritance pattern of mtDNA has made it an invaluable tool for tracing human evolutionary history. The concept of 'mitochondrial Eve' — the most recent common ancestor of all living humans through the maternal line — has been estimated to have lived approximately 150,000 years ago in Africa. However, this does not mean she was the only woman alive at the time; rather, she is the only one whose unbroken maternal lineage has survived to the present day." Mitochondrial Eve was the only woman alive 150,000 years ago. a) TRUE b) FALSE c) NOT GIVEN

Passage excerpt: "The concept of 'sustainable development' was popularized by the 1987 Brundtland Report, which defined it as 'development that meets the needs of the present without compromising the ability of future generations to meet their own needs.' This definition has become the cornerstone of international environmental policy and has influenced agreements such as the Paris Climate Accord of 2015. Sustainable development rests on three pillars: economic growth, environmental protection, and social equity. Critics argue that these three goals are often in conflict, with economic growth frequently taking precedence over environmental and social concerns. Others counter that sustainable development is not just an environmental concept but a framework for achieving long-term prosperity for all." According to the Brundtland Report, what is sustainable development? a) Development that prioritizes economic growth above all else. b) Development that meets the needs of the present without compromising future generations' ability to meet their needs. c) Development that focuses exclusively on environmental protection. d) Development that ensures all future generations have access to technology.

Passage excerpt: "The theory of evolution by natural selection, independently conceived by Charles Darwin and Alfred Russel Wallace in the mid-19th century, remains one of the foundational principles of biology. Darwin spent five years sailing on the HMS Beagle, during which he observed the diverse flora and fauna of the Galapagos Islands. He noticed that finches on different islands had different beak shapes adapted to their specific diets. Darwin published his theory in On the Origin of Species in 1859, arguing that individuals with traits better suited to their environment are more likely to survive and reproduce, passing those advantageous traits to their offspring. The theory revolutionized our understanding of the natural world and continues to shape modern biological research." What observation did Darwin make about finches on the Galapagos Islands? a) All finches had identical beak shapes regardless of their diet. b) Finches on different islands had different beak shapes adapted to their specific diets. c) Finches on the islands were more colorful than those on the mainland. d) Finches on the islands had migrated from South America only recently.

Passage excerpt: "Plate tectonics is the scientific theory explaining that the Earth's outer shell, or lithosphere, is divided into large plates that move relative to one another over the semi-fluid asthenosphere beneath. This movement is driven by convection currents in the Earth's mantle, where hot material rises, cools, and sinks in a continuous cycle. At divergent boundaries, plates move apart, allowing magma to rise and create new crust, as seen at the Mid-Atlantic Ridge. At convergent boundaries, plates collide, often resulting in one plate being subducted beneath another, forming deep ocean trenches and volcanic mountain ranges. At transform boundaries, plates slide past each other horizontally, causing earthquakes, as along the San Andreas Fault in California." The Mid-Atlantic Ridge is an example of a convergent plate boundary. a) TRUE b) FALSE c) NOT GIVEN d) TRUE AT CERTAIN SECTIONS

Passage excerpt: "In 1952, Raymond Cattell and his colleagues used a statistical technique called factor analysis to study human personality. Cattell believed that by analyzing patterns of behavior, he could identify the fundamental dimensions of personality. He reduced thousands of descriptive words to 16 core factors, which he called source traits. These 16 factors form the basis of the 16PF Questionnaire, still used today in career counseling and clinical psychology. However, some psychologists argue that Cattell's method produced too many factors and that a simpler five-factor model is more reliable." What statistical technique did Cattell use to study personality? a) Regression analysis b) Factor analysis c) Case study method d) Double-blind experimentation

Passage excerpt: "Artificial intelligence (AI) has made remarkable strides in natural language processing over the past decade. Modern AI systems can now generate coherent text, translate languages with increasing accuracy, and even write code. However, these systems are fundamentally limited by their reliance on pattern recognition rather than true understanding. They produce responses based on statistical probabilities derived from training data, without grasping the underlying meaning of the words they process." AI systems described in the passage possess genuine understanding of language. a) TRUE b) FALSE c) NOT GIVEN
