I saw that P : but seeing my host in this mood Q : I deemed it proper to take leave R : as I had frequently done before S : it had been my intention to pass the night there The Proper sequence should be:

The correct answer is: A. QPSR

The sentence is about the speaker’s decision to leave his host’s house. The speaker had intended to stay the night, but he saw that his host was in a bad mood and decided to leave instead. The correct sequence of the sentences is:

1. I saw that it had been my intention to pass the night there.
2. But seeing my host in this mood, I deemed it proper to take leave.
3. As I had frequently done before.

The first sentence establishes the speaker’s intention to stay the night. The second sentence explains why the speaker changed his mind. The third sentence provides additional information about the speaker’s previous visits to his host’s house.

The other options are incorrect because they do not follow the logical order of events. Option B, QRPS, reverses the order of the first two sentences. Option C, SPQR, puts the third sentence before the first two sentences. Option D, SRPQ, puts the third sentence after the second sentence.
