C ommas and the Adjective Clause (Continued)
 Lesson 2-25
Prompt:As we have found, adjective clauses may or may not be marked off by commas — the writer decides. The adjective clause is marked off by commas when the clause is just added information and is not necessary to the full meaning of the independent clause.
Directions:Below are listed complex sentences with adjective clauses. Do the following: 1) click to select the adjective clause in each sentence, and 2) click to select below each sentence whether the clause in the prior sentence should be marked off by commas or have no commas. Commas have been purposely omitted where necessary.
