Reading Passage: Climate change, driven primarily by human activities, is having profound effects on marine ecosystems worldwide. Rising global temperatures are causing sea levels to increase, leading to the loss of critical habitats such as coral reefs and mangrove forests. Additionally, changes in ocean chemistry due to increased carbon dioxide levels are threatening the survival of marine species that rely on calcium carbonate for their shells and skeletons. These disruptions are not only endangering individual species but also disrupting entire food webs within marine ecosystems. Scientists are working diligently to understand the full extent of these impacts and to develop strategies for conservation and adaptation. Questions: 1. What is the main cause of climate change according to the passage? A) Natural disasters B) Human activities C) Marine ecosystems D) Global temperatures 2. Which marine habitats are mentioned as being at risk due to rising sea levels? A) Kelp forests B) Coral reefs C) Seagrass beds D) Rock formations 3. Based on the passage, what is the primary threat to marine species' survival? A) Pollution B) Habitat loss C) Overfishing D) Ocean chemistry changes 4. Inference question: What can be inferred about the relationship between rising global temperatures and marine ecosystems? A) Marine ecosystems are not affected by global temperatures. B) Rising global temperatures have no impact on sea levels. C) Marine ecosystems are vulnerable to changes in global temperatures. D) Marine species are adapting easily to rising global temperatures. 5. What is the rhetorical purpose of the passage? A) To entertain readers with stories of marine life B) To inform readers about the impact of climate change on marine ecosystems C) To persuade readers to take action against climate change D) To confuse readers about the effects of global warming 6. Sentence Insertion: Which of the following sentences best fits into the passage in the paragraph discussing ocean chemistry changes? A) 'Marine biologists are studying the effects of climate change on sea turtles.' B) 'Researchers are investigating how ocean acidification affects shell-building organisms.' C) 'Tourism has been a major source of income for coastal communities.' D) 'Governments worldwide are implementing policies to reduce carbon emissions.' 7. Summary question: Which of the following best summarizes the main idea of the passage? A) Climate change is causing marine species to migrate to colder waters. B) Human activities are negatively impacting marine ecosystems through rising global temperatures and ocean chemistry changes. C) Marine conservation efforts have successfully reversed the effects of climate change on coral reefs. 8. Negative factual information: According to the passage, which of the following statements is NOT true? A) Rising global temperatures are affecting marine ecosystems. B) Ocean chemistry changes are not a concern for marine species. C) Scientists are studying the impacts of climate change on marine ecosystems. D) Coral reefs and mangrove forests are losing critical habitats due to sea level rise. Answer Key: 1. (B) 2. (B) 3. (D) 4. (C) 5. (B) 6. (B) 7. Answer: (B) 8. (B)
