Dust
Bacteria
Arsenic
Algae
Answer is Right!
Answer is Wrong!
The correct answer is: B. Bacteria
Surface water is not a better source of drinking water because it is poor in bacteria. In fact, surface water is often contaminated with bacteria, which can cause serious health problems.
Dust, arsenic, and algae are all present in surface water, but they are not as harmful as bacteria. Dust can cause respiratory problems, but it is not usually harmful to the body. Arsenic is a toxic metal that can cause cancer, but it is not usually found in high levels in surface water. Algae can produce toxins that can cause illness, but it is not usually found in high levels in surface water.
The best way to ensure that your drinking water is safe is to filter it or boil it before drinking it.
