34. Assertion (A) Stubble burning in agricultural farms creates air pollution and degrades air quality.
Reason (R) Crop residue or stubble can be used to make ethanol which can be used as substitute of petrol.
A and R are correct and R explains A
A and R are correct but R does not explains A
A is correct but R is wrong
A is wrong but R is correct
Correct Answer :
A and R are correct but R does not explains A
Solution
- Assertion (A): Stubble burning creates air pollution and degrades air quality. This is correct as burning stubble releases particulate matter, CO2, and other pollutants into the air.
- Reason (R): Crop residue can be used to produce ethanol, which serves as a substitute for petrol. This is also correct as crop residue can be converted into biofuel like ethanol through processes like fermentation.
However, R does not explain A, as the production of ethanol from crop residue does not directly address the issue of stubble burning causing air pollution. Instead, it is a potential alternative use for crop residue.
