Question

Where are the commas required

Despite three cups of coffee Danny could not keep his eyes open for another one
of Dr. O'Sullivan's long dreary lectures on Egyptian pharaohs. So he doodled in his
notebook wishing that he had chosen a different class to satisfy his history.

Answer 1

Commas in sentences delineate nonessential information or introductory elements. The placement of commas depends on whether the information is essential to the meaning of a sentence. Introductory commas and serial commas are commonly used to clarify meaning.

Step-by-step explanation:

In the given sentence, commas are required in two places:

1. After 'Despite three cups of coffee' to separate the introductory phrase from the main clause.
2. Before 'to satisfy his history' to set off the nonessential information.

The corrected sentence would be:

Despite three cups of coffee, Danny could not keep his eyes open for another one of Dr. O'Sullivan's long dreary lectures on Egyptian pharaohs. So he doodled in his notebook, wishing that he had chosen a different class to satisfy his history.
