Question

where should commas be added in the following sentences 1.Combine flour shortening pecans and cold water to make a tasty pie crust A. after the words "flour and Shortening"B.after the words "flour," "shortening" and "pecans"C.No commas added

Answer 1

The answer is B like a list the words need to have a comma separating them

Answer 2

The correct option is letter "A": commas should be added after the words "flour and Shortening".

Combine flour, shortening, pecans and cold water to make a tasty pie crust.

We use commas to separate and enumerate elements in a serie of three or more items. However, it is unnecessary to use a comma before "and".

Option "B" may be justified by those people who prefer using a comma before the last item in a list. This is known as the Oxford Comma or Serial Comma in a written style. But, this is more frequent in American English rather than in British English.
