Question

Why can contamination of drinking water occur in developed countries? How do you know?

(A) It can occur because of the lack of toilets in developed countries: "They do not use a toilet. It is
particularly common in South Asian countries like India and Nepal."
(B) It can occur due to lack of access to drinking water in developed countries: "There, more than 25
percent of the population must walk 30 minutes or more to collect water."
(C) It can occur because some people have to handle fecal matter in developed countries: "They must also
remove human waste themselves, collecting it and hauling it out of the home."
(D) It can occur due to infrastructure failures in some places in developed countries: "Expansive pipelines
supply quality water to both cities and rural areas."

Answer 1

Answer: D

Some areas in developed cities have very bad quality pipelines. These can make fecal matter spill out and make drinking water not safe and dirty. So, the answer to the question should be option D.
