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.
A is true but R is false
To determine the correct answer, let's analyze both the assertion and the reason given in the question:
- Assertion (A): Sewage treatment is essential to prevent diseases and deaths.
- This statement is true. Sewage contains harmful microorganisms, toxins, and waste products that can contaminate water supplies, leading to various waterborne diseases such as cholera, dysentery, and typhoid. Proper sewage treatment removes these contaminants, thereby preventing disease outbreaks and protecting public health.
- Reason (R): Sewage is a solid waste which causes water pollution and soil pollution.
- This statement is incorrect. Although sewage can contribute to water and soil pollution, it is typically not classified purely as solid waste. Sewage primarily consists of a combination of both liquid and solid waste. The liquid portion carries a significant risk of pollution and spreading diseases if not treated properly. Therefore, defining sewage solely as solid waste is inaccurate.
Based on the analysis above, the assertion (A) is true as sewage treatment is crucial for the prevention of diseases. However, the reason (R) is false as sewage is not purely a solid waste; it is a combination of both liquid and solid wastes, which needs proper treatment to prevent pollution.
Thus, the correct answer is: A is true but R is false.
