Answer:
b. Dr. Clemons states, “Keats demonstrated a keen sense of delivery.”
Step-by-step explanation:
In the above case, the period (.) or full stop must be after the punctuation (double quotes). The period (.) is supposedly the simplest punctuation mark to learn. It ends with any sentence. The difficulty usually ensues when the period is included with other punctuations.
When writers get mixed up about full stops or periods, it is generally because they are not sure as to where to put them with regard to other adjoining punctuation. The most general use of the full stop or period ends a declarative sentence.
However, there is a difference between using the period after and before punctuation. In British English, the period is called a full stop and is used after the closing punctuation mark; however, in American English, the period usually goes inside or before the closing punctuation mark at the conclusion of a sentence.
