Identify which rule applies to the following sentence.

Jeff Doolittle, PhD, and Dorothy Watts, CPA, were both at the dinner last night.
a. Place a comma after a coordinating conjunction.
b. Place a comma after a dependent clause.
c. Abbreviations written after individuals’ names are set off by commas.

The correct answer is:

Abbreviations written after individuals’ names are set off by commas (c.)

Explanation:

Abbreviations such as M.D, PhD, M.A, D.D.S, etc, used after the names of individuals are set off with a comma, and the comma is used both before and after the name of the individual. In this example; 'Jeff Doolittle, PhD, and Dorothy Watts, CPA, were both at the dinner last night', the rule was applied correctly because the comma was used before and after the abbreviations 'PhD' and 'CPA'. If the comma is not used before the abbreviation following a name, then it is not used after the abbreviation. For example: 'Mr. Smith Moody M.D. is my family physician' is correctly used, because no comma is used before the abbreviation, hence it is not also used after the abbreviation. It would be wrong to write it like this: Mr. Smith Moody M.D., is my family physician' .

There are other rules of using a comma, I suggest you check them up for wholesome understanding.

it's like watching a fable, it's not really about the animals but rather it has a meaning that is understood by us and that is implicit, not explicitly said. implicit ideas are common and are used in almost all works of art, from writing to painting to sculpting.

the sentence does not violate the phrase structure second rule (introduced by noam chomsky) because noun phrases consist of a determiner such as a, the or every, and a noun. in the sentence, the noun phrase the cake includes a determiner (the) and a noun (cake).

on the other hand, the first rule indicates that a sentence encloses a noun phrase, followed by a verb phrase. the example sentence can be analysed as follows:

john (n) + ate (v) + the (det) + cake (n).
