Explanation
Correct answer: B.
Choice B is the best answer. The convention being tested is the punctuation of items in a complex series (a series including internal punctuation). In this choice, the semicolon after “Lagos” is conventionally used to separate the first item (“The Joys…Lagos”) and the second item (“A Kind…Nigeria”) in the series. Further, the comma after “Marriage” correctly separates the title “A Kind of Marriage” from the supplementary phrase (“a television…Nigeria”) that describes it.
Why the other choices are wrong
Choice A
Choice A is incorrect because the comma after “Lagos” doesn’t match the semicolon used later in the series to separate the second item (“A Kind…Nigeria”) from the third item (“and…autobiography”).
Choice C
Choice C is incorrect because the comma after “Lagos” doesn’t match the semicolon used later in the series to separate the second item (“A Kind…Nigeria”) from the third item (“and…autobiography”). Additionally, a colon can’t be used in this way to separate the title “A Kind of Marriage” from the supplementary phrase (“a television…Nigeria”) that describes it.
Choice D
Choice D is incorrect because it fails to use appropriate punctuation to separate the title “A Kind of Marriage” from the supplementary phrase (“a television…Nigeria”) that describes it.
