University Quiet Hours Policy Announcement The university has announced a new policy regarding quiet hours in all campus dormitories. Effective immediately, quiet hours will be from 10 PM to 8 AM every day, including weekends. This change aims to create a more conducive environment for studying and sleeping. Residents are expected to minimize noise levels during these hours. The university believes this will improve academic performance and overall well-being. Violations of the policy may result in warnings or disciplinary actions. Student Conversation on Quiet Hours Student A: Hey, did you hear about the new quiet hours policy in the dorms? Student B: Yeah, I did, and honestly, I think it's a great idea. I mean, last semester, it was really hard to concentrate with all the noise late at night. Student A: I see what you mean. But do you really think it'll make a difference? Student B: For sure! First, it'll definitely help people who have early classes or exams. They can actually get a good night's sleep. Plus, it encourages everyone to be more respectful of each other's space. Student A: But what about on weekends? Isn’t it a bit too strict? Student B: Maybe, but I think it’ll be worth it if it means fewer complaints and a better atmosphere overall. People can still hang out, just more quietly. Summary of the Announcement and Student Opinion The reading passage explains that the university now enforces quiet hours from 10 PM to 8 AM daily in dormitories to support better study and sleep environments. In the conversation, the student supports this policy. Firstly, they believe it will help students who have early classes by allowing them to sleep well. Secondly, the student thinks this policy encourages respect among residents, reducing noise complaints. Although they acknowledge that weekend restrictions might be strict, they argue the overall benefits make it worthwhile for a more peaceful dorm atmosphere.

The Importance of Coral Reefs Coral reefs, often referred to as the "rainforests of the sea", are among the most diverse and valuable ecosystems on Earth. These underwater structures are primarily composed of calcium carbonate, which is secreted by coral polyps. Found in tropical ocean waters around the world, coral reefs cover less than 1% of the ocean floor but are home to more than 25% of all marine species. This biodiversity makes coral reefs crucial for maintaining the ecological balance of the oceans. The biodiversity supported by coral reefs extends to many levels of the food chain. Numerous fish species, including commercially important ones, depend on reefs for food, breeding grounds, and shelter from predators. Invertebrates, such as mollusks and crustaceans, also thrive in these environments, contributing to the complex food webs that sustain larger marine animals like sharks and sea turtles. The health of coral reefs, therefore, directly impacts the productivity and stability of marine ecosystems. In addition to supporting marine life, coral reefs play a significant role in protecting coastal areas from the destructive forces of waves and storms. The physical structure of reefs acts as a natural barrier that dissipates wave energy, thereby reducing coastal erosion and preventing damage to coastal communities. This function is particularly important in regions prone to tropical storms and hurricanes. As climate change intensifies weather events, the protective role of coral reefs becomes even more critical. Economically, coral reefs contribute significantly to the livelihoods of millions of people. They support tourism and fishing industries, which are vital sources of income in many coastal regions. Tourists flock to coral reefs for recreational activities such as snorkeling and scuba diving, attracted by the vibrant underwater landscapes and diverse marine life. Moreover, the fishery resources provided by reefs are essential for food security in numerous developing countries. Despite their importance, coral reefs face numerous threats, primarily from human activities. Overfishing, pollution, and coastal development have all contributed to the degradation of these ecosystems. More recently, climate change has emerged as a major threat, causing coral bleaching events that weaken or kill coral colonies. When water temperatures rise, corals expel the symbiotic algae living in their tissues, leading to bleaching. Without these algae, corals lose their main source of nutrition and are more susceptible to disease. Efforts to conserve and restore coral reefs are underway globally. Marine protected areas (MPAs) have been established to reduce human impact and promote sustainable use of reef resources. Additionally, innovative approaches such as coral gardening and artificial reef construction aim to replenish damaged areas. Public awareness campaigns and community involvement are also crucial in fostering a sense of stewardship among those who depend on reefs for their livelihoods. In conclusion, coral reefs are indispensable to marine biodiversity, coastal protection, and the global economy. Preserving these vital ecosystems is essential not only for the myriad species they support but also for the human communities that rely on them. As threats to coral reefs continue to grow, concerted conservation efforts will be necessary to ensure their survival for future generations. Questions 1.
