b. Sewage system.
Country life is healthier than city life because it's free of both air and water pollution due to too much noise and garbage, less stress and proximity to nature.
Step-by-step explanation:
This passage was written to compare life in the city and life in the country. Since, all humans are created differently, we all have different life choices and preferences; some people enjoy living within big cities where there are efficient transport system, sewage system, banking system, communication system, and other developmental infrastructures while some other persons are averse to city life and as such would prefer living in the country because it's quiet, peaceful and healthy.
According to the passage, the two better systems found in the city are;
a. Transport system: people are able to move from one part of the city quickly and easily.
b. Sewage system: there's an effective and efficient waste disposal system for used (dirty) water in the kitchen and toilet.
Also, the city offer its habitants better services such as;
c. Internet.
d. Telephone.
e. Electricity.
Social life is better in the cities because there is more entertainment, cinemas, shopping centers, art gallery, concert halls, theaters, restaurants and cafes where people could go to at their leisure time to relax, unwind and have fun.
Basically, country life is healthier than city life because it's free of both air and water pollution due to too much noise and garbage, less stress and proximity to nature.
