Question

Which sentence does not contain any errors in period usage?

a. Have you read The Hobbit by J. R. R. Tolkien?
b. My brother's platoon leader is Lt Brian Lee.
c. Rev Jesse L. Jackson has run for public office.
d. Sgt Eva Miller will be able to answer your question.

Answer 1

The sentence does not contain any errors in period usage is letter (A) Have you read The Hobbit by J. R. R. Tolkien? Letter B is lacking a period after 'Lt'. Letter C lacks period after 'Rev' and letter D lacks a period right after the word 'Sgt.' As much as possible, contracted titles should have periods right after it.
