Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.
Covering more than 70 percent of our planet, oceans are among the earth’s most valuable natural resources. They govern the weather, clean the air, help feed the world, and provide a living for millions. They also are home to most of the life on earth, from microscopic algae to the blue whale, the largest animal on the planet. Yet we’re bombarding them with pollution. By their very nature—with all streams flowing to rivers, all rivers leading to the sea—the oceans are the end point for so much of the pollution we produce on land, however far from the coasts we may be. And from dangerous carbon emissions to choking plastic to leaking oil to constant noise, the types of ocean pollution humans generate are vast. As a result, collectively, our impact on the seas is degrading their health at an alarming rate. Here are some ocean pollution facts that everyone on our blue planet ought to know.
When we burn fossil fuels, we don’t pollute just the air but the oceans, too. Indeed, today’s seas absorb as much as a quarter of all man-made carbon emissions, which changes the pH of surface waters and leads to acidification. This problem is rapidly worsening—oceans are now acidifying faster than they have in some 300 million years. It’s estimated that by the end of this century, if we keep pace with our current emissions practices, the surface waters of the ocean could be nearly 150 percent more acidic than they are now.
The majority of the garbage that enters the ocean each year is plastic—and here to stay. That’s because unlike other trash, the single-use grocery bags, water bottles, drinking straws, and yogurt containers, among eight million metric tons of the plastic items we toss (instead of recycle), won’t biodegrade. Instead, they can persist in the environment for a millennium, polluting our beaches, entangling marine life, and getting ingested by fish and seabirds.
Where does all this debris originate? While some is dumped directly into the seas, an estimated 80 percent of marine litter makes its way there gradually from land-based sources―including those far inland―via storm drains, sewers, and other routes. Oil from boats, airplanes, cars, trucks, and even lawn mowers is also swimming in ocean waters. Chemical discharges from factories, raw sewage overflow from water treatment systems, and storm water and agricultural runoff add other forms of marine-poisoning pollutants to the toxic brew.
The ocean is far from a “silent world.” Sound waves travel farther and faster in the sea’s dark depths than they do in the air, and many marine mammals like whales and dolphins, in addition to fish and other sea creatures, rely on communication by sound to find food, mate, and navigate. But an increasing barrage of human-generated ocean noise pollution is altering the underwater acoustic landscape, harming—and even killing—marine species worldwide.

Đáp án A
Câu nào trong các câu sau thể hiện ý chính của đoạn văn tốt nhất?
A. Đại dương đang bị ô nhiễm bởi nhiều nguồn ô nhiễm khác nhau.
B. Đại dương mang lại nhiều lợi ích cho con người trên Trái Đất.
C. Rác thải từ các hoạt động của con người là nguyên nhân gây ô nhiễm đại dương.
D. Con người nên biết họ đã làm gì đại dương.
=> Đọc qua các đoạn, ta sẽ có cái nhìn chung về toàn bài như sau:
+ Đoạn 1: Nêu ra vai trò biển cả và thực trạng đáng báo động về sự ô nhiễm đại dương của chúng ta
+ Đoạn 2: Những nguồn gây ô nhiễm và hậu quả tương ứng mà môi trường, hành tinh chúng ta sẽ phải gánh chịu
+ Đoạn 3: Nguồn gốc chính của những rác thải đó đến từ đâu
+ Đoạn 4: Những tác động đối với môi trường sinh sống của sinh vật biển
=> Qua các tiêu đề chính cho mỗi đoạn, ta có thể dễ thấy được vấn đề mà bài đang nói đến là sự ô nhiễm đại dương và nguyên nhân cũng như hậu quả của nó. Phân tích các lựa chọn, ta thấy như sau:
A. Đáp án này hợp lý nhất. Về ý thứ nhất, nó đang nói đến việc đại dương bị ô nhiễm là điều rõ ràng. Và về ý thứ hai, nguyên nhân của nó đến từ các nguồn ô nhiễm khác nhau. Thực tế, nhìn chung các hoạt động đều có nguồn gốc từ con người, nhưng tác động trực tiếp do họ gây ra sự ô nhiễm đại dương là không lớn, mà chủ yếu là các ảnh hưởng mang tính gián tiếp và kéo theo từ nhiều nguồn khác nhau, điều này sẽ thấy cụ thể hơn ở đoạn thứ 3
B. Đáp án này loại đầu tiên vì nó thực tế chỉ được nhắc qua trong nửa đoạn đầu
C. Đáp án này chưa chính xác và nó còn mang tính hạn chế nội dung toàn bài khi chỉ có ý nhấn mạnh đến "waste- rác thải" từ các hoạt động của con người. Thực tế như đã phân tích ở đáp án A, đúng là có thể khẳng định rằng hầu hết mọi hoạt động và sự vận hành cuộc sống đều có nguồn gốc là từ con người, nhưng nếu chỉ giới hạn nó trong "activities" thì nó chưa thực sự bao quát được các nguyên nhân dẫn đến ô nhiễm biển, vì nó còn bao gồm các ảnh hưởng khác như đất đai, cống rãnh, nông nghiệp,...như được đề cập đến đoạn 3
D. Đáp án này thiên về việc phân tích đến hoạt động con người đối với đại dương cũng như những cảnh báo mà tác giả muốn nhắm đến con người, để ám chỉ rằng họ nên nhận thức được hành động của mình. Trong khi bài ở đây lại tập trung đến những nguyên nhân và hậu quả của việc ô nhiễm đại dương, do đó không phù hợp.

CÂU HỎI HOT CÙNG CHỦ ĐỀ
Câu 1:
Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.
National parks play a highly valuable role in documenting climate change. Researchers have utilized the vast tracts of pristine wilderness to collect data on species and habitats. At first, they collected observational data on foot; now, they use sophisticated methods such as aerial surveillance with drones like those used in Northrop Grumman’s Wildlife Challenge to collect information on polar bears.
Observational longitudinal data collection shows the effects of climate change that impact vegetation and animal species. The pika is the perfect example of an animal who may need to be relocated from the parks due to climate change, as described in Smithsonian Magazine. The park service is taking this very seriously. “It is … openly discussing the possibility of “assisted migration”: manually relocating some animals and plants if it turns out they can’t survive within the park’s changing landscapes.”
National park research also documents glacier retreat, finding that some ice fields have lost as much as 85 percent in the last five decades, according to U.S. Geological Survey. Glacier Park might be recognizable only as a historical name by 2030, it projects. It’s not just glaciers retreating. The Conversation notes that national park data shows that trees are also affected by climate change: “Climate change is killing trees due to increased drought, changes in wildfire patterns and increased bark beetle infestations. Tracking of trees in … national parks has contributed to a database that revealed how climate change has doubled tree mortality since 1955 across the western United States.”
We should not forget that at its inception, the National Parks Service’s long-term intention was to protect the parks and “leave them unimpaired for the enjoyment of future generations.”
