Đọc kĩ đoạn văn sau và chọn phương án đúng (ứng với A hoặc B, C, D) cho mỗi câu hỏi:
Water pollution is the contamination of bodies of water such as lakes, rivers, oceans, and groundwater (the water beneath the Earth’s surface). It is one of the most serious types of pollution.
Water pollution can have many different causes. Factories dump industrial waste into lakes and rivers. Sewage from households is another cause. Farms using pesticides to kill insects and herbicides to kill weeds can lead to water pollution. These factors cause ‘point source’ pollution while pollutants from storm water and the atmosphere result in ‘non-point source’ pollution.
Water pollution can have dramatic effects. In poor nations, there are frequent outbreaks of cholera and other diseases because of people’s drinking untreated water. Humans can even die if they drink contaminated water. Polluted water also causes the death of squatic animals such as fish, crabs, or birds. Other animals eat these dead animals and may also get sick.
So what should we do to reduce water pollution?
According to the passage, what is ground water?
A.the water in the sea
B.the water in rivers
C.the water in the lakes
D.the water underground
