Explanation
Correct answer: A.
Choice A is the best answer. By noting that Selvon is a Trinidadian author and indicating that The Lonely Londoners, published in 1956, is about a group of men who emigrate from the Caribbean to Great Britain after World War II, the sentence effectively introduces Samuel Selvon and his novel to a new audience.
Why the other choices are wrong
Choice B
Choice B is incorrect. The sentence indicates the order in which two of Selvon’s novels were written; it doesn’t introduce Samuel Selvon and The Lonely Londoners to a new audience.
Choice C
Choice C is incorrect. While the sentence describes the novel The Lonely Londoners, it doesn’t mention its author, Samuel Selvon, by name and thus doesn’t effectively introduce him to a new audience.
Choice D
Choice D is incorrect. The sentence indicates that two of Selvon’s novels include the same characters; it doesn’t introduce Samuel Selvon and The Lonely Londoners to a new audience.
