Discussion
Read the following statements :
Assertion (A) : Sewage treatment is essential to prevent diseases and deaths.
Reason (R) : Sewage is a solid waste which causes water pollution and soil pollution.
Choose the correct option.
Answer: C
A is true but R is false.
Sewage carries disease-causing microbes and harmful substances; untreated, it contaminates water and spreads diseases such as cholera and typhoid. Treating it is essential to prevent disease and death, so A is true.
R is false because sewage is a liquid waste: water from homes, industries and hospitals carrying dissolved and suspended impurities. It is not a solid waste, so the options calling R true are wrong.
