S1: Throughout history man has used energy from the sun. P : Today, when we burn wood or use electric current we are drawing an energy. Q : However we now have a new supply of energy. R : All our ordinary life depends on sun. S : This has come from the sun. S6: This energy comes from inside atoms. The Proper sequence should be: A. SQPR B. RQPS C. QSRP D. PSRQ

The correct answer is D. PSRQ.

Here is a brief explanation of each option:

• Option A: SQPR. This option is incorrect because it does not follow the logical order of the sentences. The sentence “All our ordinary life depends on sun” should come before the sentence “This energy comes from inside atoms.”
• Option B: RQPS. This option is incorrect because it does not follow the logical order of the sentences. The sentence “Today, when we burn wood or use electric current we are drawing an energy” should come before the sentence “However we now have a new supply of energy.”
• Option C: QSRP. This option is incorrect because it does not follow the logical order of the sentences. The sentence “This has come from the sun” should come before the sentence “Throughout history man has used energy from the sun.”
• Option D: PSRQ. This option is correct because it follows the logical order of the sentences. The sentence “Throughout history man has used energy from the sun” comes first, followed by the sentence “All our ordinary life depends on sun,” then the sentence “This energy comes from inside atoms,” and finally the sentence “Today, when we burn wood or use electric current we are drawing an energy.”
