The correct answer is: A. PSQR
Here is a brief explanation of each option:
- PSQR: This is the correct sequence. The first sentence (S1) introduces Jawaharlal Nehru as a great plan-enthusiast. The second sentence (P) provides evidence of this, stating that Nehru advised the pre-Independent congress to set up the National Planning Commission in 1938. The third sentence (R) explains where Nehru got the idea for a national planning commission, from Russia. The fourth sentence (Q) points out that Nehru’s plan was not feasible in India, as it was a democratic country. The fifth sentence (S) states that Nehru himself became the chairman of the commission.
- SRQP: This option is incorrect because it places the third sentence (R) before the second sentence (P). This is not possible, as the second sentence provides evidence of the first sentence.
- QPRS: This option is incorrect because it places the fourth sentence (Q) before the third sentence (R). This is not possible, as the third sentence explains where Nehru got the idea for a national planning commission, which is necessary information to understand the fourth sentence.
- RQSP: This option is incorrect because it places the fifth sentence (S) before the second sentence (P). This is not possible, as the second sentence provides evidence of the first sentence.
