readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
Ada Lovelace
B
Ada Lovelace,
C
Ada Lovelace—
D
Ada Lovelace, she
Correct Answer: A
Choice A is the best answer. The name "Ada Lovelace" is essential information required to specify which mathematician is being discussed. Therefore, no punctuation should separate the title "mathematician" from the name.
Choices B and C are incorrect because they use punctuation (comma, dash) to incorrectly set off essential information. Choice D is incorrect because it adds the redundant pronoun "she," making the sentence ungrammatical.
