1 : Yesterday, I chanced to meet P : where he lived Q : and asked him R : now in his seventies S : an old acquaintance, 6 : and what he did for his living. The Proper sequence should be:

The correct answer is A. PSRQ.

Here is a brief explanation of each option:

• Option A: PSRQ. This is the correct sequence because it follows the natural order of events. The speaker first met the acquaintance, then asked him where he lived and what he did for a living.
• Option B: QPSR. This option is incorrect because it places the question about where the acquaintance lived before the speaker met him.
• Option C: RQPS. This option is incorrect because it places the question about what the acquaintance did for a living before the speaker met him.
• Option D: SRQP. This option is incorrect because it places the question about where the acquaintance lived after the speaker met him.

I hope this helps! Let me know if you have any other questions.
