History
Read both passages. Passage A: Butterflyfish are a very colorful species. Their vibrant yellow markings make them easy to identify in the sea. These fish are found in various reefs throughout the world. Coral reefs provide the tropical fish with protection from predators, and they are an excellent source of food. Over the past few decades, butterflyfish have been impacted by increased water pollution. Many harmful and toxic substances have entered into bodies of water from land. This includes things like chemicals, garbage, and oil. This impacts the quality and health of the water for marine wildlife. As a result, it can destroy coral reefs. Without the butterflyfish's reef habitat, it is a challenge for them to survive. This is because they are exposed to predators. It is estimated that water pollution will continue to rise, which means many species, not just the butterflyfish, will be at great risk. Passage B: Over the last few decades, water pollution has been on the rise. Approximately 80 percent of water pollution is caused by human activities on land. Run off, disposal of waste, and oil spills are only a few factors. Ultimately, water pollution compromises the quality of the water. It causes an excess of nutrients in the water, which is very dangerous. This means that many marine ecosystems, like coral reefs, are affected. Coral reefs are diverse ecosystems and home to many types of wildlife. One in particular is the butterflyfish. They are yellow, white, and black and have long snouts. Since coral reefs are being destroyed, it means butterflyfish are losing their habitat. However, it is not just the loss of their habitat that is impacting their population. It is also the quality of the water they are swimming in. As a result, the butterflyfish are dying and are now under threat of extinction. Select the sentence that best combines information from both passages. Butterflyfish are at risk due to habitat loss and predators. Butterflyfish are at risk due to habitat loss and water pollution. Butterflyfish are at risk due to water pollution and excess nutrients. Butterflyfish are at risk due to water pollution and oil spills
