Assertion(A) and Reason(R) are given below, Choose the correct option:
Assertion (A): Annual growth rate reflects the pace at which population increases in a given year.
Reason (R): A 2% annual growth rate means two new persons are added per 100 persons in the base population.
अभिकथन (A) और कारण (R) नीचे दिए गए हैं। सही विकल्प चुनिए :
अभिकथन (A): वार्षिक वृद्धि दर उस गति को दर्शाती है, जिस दर से किसी दिए गए वर्ष में जनसंख्या बढ़ती है।
कारण (R): 2% वार्षिक वृद्धि दर का अर्थ है कि आधार जनसंख्या के प्रत्येक 100 व्यक्तियों पर 2 नए व्यक्ति जुड़ते हैं।
Detailed Solution & Logic
Both A and R are true, and R is the correct explanation of A/ A और R दोनों सत्य हैं, तथा R, A की सही व्याख्या है।
Explanation / व्याख्या:
Assertion (A):
Annual growth rate tells us how fast the population is increasing in one year.
वार्षिक वृद्धि दर बताती है कि एक वर्ष में जनसंख्या कितनी तेजी से बढ़ रही है।
So, Assertion is true.
इसलिए, कथन (A) सत्य है।
Reason (R):
If the annual growth rate is 2%, it means that for every 100 persons in the original population, 2 persons are added in one year.
यदि वार्षिक वृद्धि दर 2% है, तो इसका अर्थ है कि मूल जनसंख्या के प्रति 100 व्यक्तियों पर 1 वर्ष में 2 व्यक्ति जुड़ते हैं।
So, Reason is also true.
इसलिए, कारण (R) भी सत्य है।
And this reason clearly explains how annual growth rate shows the speed of population increase.
और यही कारण स्पष्ट करता है कि वार्षिक वृद्धि दर जनसंख्या बढ़ने की गति को कैसे दर्शाती है।
Extra Facts / अतिरिक्त तथ्य:
-
Population growth rate is usually expressed in percentage (%).
जनसंख्या वृद्धि दर सामान्यतः प्रतिशत (%) में व्यक्त की जाती है। -
A higher annual growth rate means population is increasing rapidly.
अधिक वार्षिक वृद्धि दर का अर्थ है कि जनसंख्या तेजी से बढ़ रही है। -
A lower annual growth rate means population is increasing slowly.
कम वार्षिक वृद्धि दर का अर्थ है कि जनसंख्या धीरे-धीरे बढ़ रही है। -
Growth rate depends on birth rate, death rate, and migration.
वृद्धि दर जन्म दर, मृत्यु दर और प्रवास (migration) पर निर्भर करती है।
