Real questions that test this

जैवइंधन वापराचे खालीलपैकी कोणते फायदे बरोबर आहेत ? / Which of the following benefits of use of Bio-fuel are correct ?

(a)जैवइंधन वनस्पतीपासुन तयार करता येते. / Bio-fuel is made from vegetations.

(b)जैवइंधनामुळे प्रदूषण कमी होईल. / Less pollution by use of bio-fuel.

(c)जैवइंधनामुळे खनिजतेल वाचविता येते. / Use of bio-fuel will save crude oil.

(d)जैवइंधन सस्त आहे. / Bio-fuel is cheap.

1)(a) आणि (b) / (a) and (b)
2)(b) आणि (c) / (b) and (c)
3)(a), (b) आणि (c) / (a), (b) and (c)
4)वरील सर्व / Above all✓ Correct

Bio-fuels are derived from plant matter (vegetation), help reduce pollution compared to fossil fuels, save depleting crude oil reserves, and are generally cost-effective or economically viable over time. Hence, all given benefits are correct.

खालीलपैकी कोणती विधाने बरोबर आहेत? / Which of the following statements are correct?

(a)पारंपरिक कार इंजन जैवइंधनावर चालू शकतात. / Conventional car engines can be run on Bio-fuel.

(b)गॅसोलीन कार नामशेष होतील. / Gasoline cars are disappearing.

(c)जैवइंधनामुळे प्रदूषण कमी होऊ शकते. / Pollution minimize due to Bio-fuels.

(d)जैवइंधनामुळे वाहनांचे इंजन बदलण्याचे कारण नाही. / No change of vehicle engines due to Bio-fuel.

1)(a) आणि (b) बरोबर / (a) and (b) correct
2)(a), (b) आणि (c) बरोबर / (a), (b) and (c) correct
3)(a), (c) आणि (d) बरोबर / (a), (c) and (d) correct✓ Correct
4)वरील सर्व बरोबर / Above all correct

Conventional car engines can handle low-level bio-fuel blends without modification, helping reduce pollution, and eliminating the immediate need to change standard vehicle engines. Gasoline cars are not vanishing overnight, making statement (b) incorrect.

खालील विधान व निष्कर्ष यांवरून योग्य पर्याय निवडा. विधान : जैवइंधन हे खनिज तेलाला पर्याय ठरू शकते. निष्कर्ष (A) : खनिज तेल निर्मितीला कोट्यवधी वर्ष लागतात. (B) : खनिज तेलाच्या उत्सर्जनामुळे विषारी वायूंची निर्मिती होते. Choose the correct alternative from Statement and Conclusion given below : Statement : Bio-fuel is alternative to crude oil. Conclusion (A) : Crude oil takes crores of years to produce. (B) : Due to crude oil, toxic gases will be created.

(a)खनिज तेल निर्मितीला कोट्यवधी वर्ष लागतात. / Crude oil takes crores of years to produce.

(b)खनिज तेलाच्या उत्सर्जनामुळे विषारी वायूंची निर्मिती होते. / Due to crude oil, toxic gases will be created.

1)निष्कर्ष (A) बरोबर व (B) चूक / Conclusion (A) correct, (B) incorrect
2)निष्कर्ष (A) आणि (B) बरोबर / Conclusion (A) and (B) correct✓ Correct
3)निष्कर्ष (A) आणि (B) चूक / Conclusion (A) and (B) incorrect
4)निष्कर्ष (A) चूक व (B) बरोबर / Conclusion (A) incorrect, (B) correct

Bio-fuels are considered an alternative to crude oil because crude oil takes millions of years to form (fossil fuel) and its burning releases harmful greenhouse gases and toxic pollutants.
