Final answer:
It is true that in running text, a title following a person's name should not be capitalized. Titles are only capitalized when they precede the person's name and are part of a formal address. Option a is the correct answer.
Step-by-step explanation:
The question "In running text, do not capitalize a title following a person's name." can be addressed by understanding the standard conventions of English grammar and capitalization rules. It is indeed true that titles following a person's name in a sentence should not typically be capitalized unless they are part of a formal title or are used as a part of a name when addressing the person.
For instance, when referring to individuals in a sentence, it is appropriate to use lowercase for their titles when the titles come after their names. This would look like: 'Atul Gawande, a doctor' or 'Tammy Baldwin, a senator'. However, if the title precedes the name, it should be capitalized, such as in 'Doctor Atul Gawande' or 'Senator Tammy Baldwin'.
This rule helps to differentiate between the formality of titles used in direct addressing versus those mentioned in passing. It maintains clarity and grammatical correctness in written English.
