Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Geothermal fluids are rich in salts and other contaminants such as hydrogen sulphide (H2S) and oxides of nitrogen (NOx).
Reason (R): They are re-injected into ground rather than being dumped to river or ponds.
In the light of the above statements, choose the most appropriate answer from the options given below:नीचे दो कथन दिए गए हैं : एक अभिकथन (Assertion A) के रूप में तथा दूसरा उसके कारण (Reason R) के रूप में।
अभिकथन (A): भूतापीय द्रव लवणों तथा हाइड्रोजन सल्फाइड (H2S) और नाइट्रोजन के ऑक्साइड (NOx) जैसे अन्य संदूषकों से समृद्ध होते हैं।
कारण (R): इन्हें नदियों या तालाबों में डालने के बजाय भूमि में पुनः अंतःक्षेपित (re-inject) किया जाता है।
उपर्युक्त कथनों के आलोक में, नीचे दिए गए विकल्पों में से सबसे उपयुक्त उत्तर चुनिए:

Show answer & explanation
Correct answer: B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A)(A) और (R) दोनों सही हैं, किंतु (R), (A) की सही व्याख्या नहीं है
Explanation
Geothermal brines really are loaded with dissolved salts, H2S and other contaminants, so (A) is correct, and spent fluid is indeed re-injected into the reservoir instead of being discharged to surface water, so (R) is correct. But re-injection is a consequence of the contamination, not its cause, so it does not explain (A). Hence both correct, (R) is not the explanation of (A).भूतापीय लवणजल में वास्तव में घुले हुए लवण, H2S तथा अन्य संदूषक भरे होते हैं, अतः (A) सही है; और प्रयुक्त द्रव को सतही जल में छोड़ने के बजाय भंडार में पुनः अंतःक्षेपित किया ही जाता है, अतः (R) भी सही है। किंतु पुनः अंतःक्षेपण संदूषण का परिणाम है, उसका कारण नहीं, इसलिए वह (A) की व्याख्या नहीं करता। अतः दोनों सही हैं, किंतु (R), (A) की व्याख्या नहीं है।More People, Development and Environment questions
