**Directions: Read the given passage carefully to answer the following questions.

Each question will have five alternatives as its answer. Choose the correct option as your answer.**

Climate change refers to long-term alterations in temperature, precipitation, wind patterns, and other elements of the Earth's climate system. This phenomenon is primarily driven by human activities, particularly the burning of fossil fuels, deforestation, and industrial processes, which have significantly increased the concentration of greenhouse gases in the atmosphere. Since the Industrial Revolution, carbon dioxide levels have risen from about 280 parts per million to over 410 parts per million. This accumulation of greenhouse gases traps heat within the Earth's atmosphere, leading to a gradual increase in global temperatures—a phenomenon commonly referred to as global warming. The effects of climate change are far-reaching and diverse, impacting both natural ecosystems and human societies. One of the most significant consequences of climate change is the increase in extreme weather events. Hurricanes, heatwaves, and heavy rainfall have become more frequent and severe, posing substantial risks to life, property, and economic stability. For instance, the hurricanes that ravaged the Gulf of Mexico in recent years are believed to have been intensified by warmer ocean temperatures. Additionally, rising temperatures have caused polar ice caps and glaciers to melt at unprecedented rates, contributing to sea-level rise. The higher sea levels threaten coastal communities with flooding and ______________ of millions of people. Furthermore, ocean acidification, a direct result of increased carbon dioxide absorption by seawater, poses serious threats to marine life, especially coral reefs and shellfish. The agricultural sector is not immune to the impacts of climate change either. Changes in temperature and precipitation patterns can lead to reduced crop yields, affecting global food security. For instance, staple crops like wheat, rice, and maize may suffer in regions that become too warm or experience erratic rainfall. Mitigating the impacts of climate change requires a multifaceted approach. Reducing greenhouse gas emissions through cleaner energy sources, enhancing energy efficiency, and fostering sustainable land use practices are essential strategies. International agreements, such as the Paris Agreement, aim to unite countries in their efforts to limit global temperature rise and promote resilience against climate-related impacts. In conclusion, climate change is an urgent and complex global challenge. The science is clear, and the evidence is compelling: human activity is driving significant changes to our climate system. Addressing this issue requires concerted efforts from all sectors of society, with an emphasis on sustainable development and international cooperation.

Scientific research plays a pivotal role in advancing our understanding of the natural world, particularly in the field of chemistry. One of the most significant areas of study within this discipline is the division and classification of elements, which are the foundational building blocks of matter. The periodic table, developed by Dmitri Mendeleev in 1869, represents a systematic arrangement of elements based on their atomic number, electron configurations, and recurring chemical properties. Elements are divided into several categories, including metals, nonmetals, and metalloids, each exhibiting distinct physical and chemical properties. Metals, which comprise the majority of known elements, are typically characterised by their lustre, malleability, ductility, and excellent conductivity of heat and electricity. Common examples of metals include iron, gold, and aluminium. Nonmetals, on the other hand, are generally poor conductors of heat and electricity and are not malleable or ductile. Examples of nonmetals include hydrogen, oxygen, and sulphur. Metalloids possess properties intermediate between metals and nonmetals and often serve as semiconductors in electronic devices. Silicon and arsenic are notable metalloids. Research into the properties of elements has uncovered numerous applications in everyday life and industry. For instance, the exceptional ________ of copper makes it invaluable for electrical wiring, while the high reactivity of fluorine is harnessed in the production of pharmaceuticals and pesticides. The noble gases, such as helium and neon, are utilised in lighting and cooling systems due to their inertness. Advances in scientific research have also led to the discovery of synthetic elements, which do not occur naturally. These man-made elements are created through nuclear reactions and have expanded our understanding of atomic structure and nuclear physics. The element technetium, for example, was the first synthetic element to be discovered and has since found applications in medical imaging. The process of scientific discovery is cumulative and iterative, relying on the meticulous work of researchers who build upon the findings of their predecessors. It involves hypothesis formulation, experimentation, observation, and refinement of theories. The development of new technologies, such as sophisticated spectroscopy techniques and particle accelerators, has enabled scientists to delve deeper into the properties and behaviours of elements at the atomic and subatomic levels. In conclusion, scientific research, particularly in the study of element division, continues to expand our understanding of the material universe. The periodic table not only classifies elements but also guides researchers in predicting chemical behaviours and discovering novel materials with remarkable properties. This ongoing quest for knowledge underscores the critical role of scientific inquiry in driving innovation and improving quality of life.
