In the following question the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct

1. Little indeed is known of the origin of English literature.

P. This has not prevented some scholars from writing their "lives" from hints in the texts themselves.

Q. So far as poets are concerned, again, little or nothing is known beyond the names of two of them.

R. We can be certain that poetry made its appearance long before the first prose was written down.

S. Critics have also relied on scanty contemporary references, and also a mass of conjecture that cannot be described as intelligent.

6. Not withstanding the mists, old English literature has an amazing richness.
