EXERCISE 28-5 Using Commas
Add any necessary commas to the following sentences, remove any commas that do not belong, and change any punctuation that is incorrect. Some sentences may be correct. Example:
César Chávez was born on March 31 1927, on a farm in Yuma, Arizona.
Chávez, who spent years as a migrant farmworker, told other farm laborers “If you’re outraged at conditions, then you can’t possibly be free or happy until you devote all your time to changing them.”
Chávez founded the United Farm Workers union and did indeed, devote all his time to changing conditions for farmworkers.
Robert F. Kennedy called Chávez, “one of the heroic figures of our time.”
Chávez, who died on April 23, 1993, became the second Mexican American to receive the highest civilian honor in the United States, the Presidential Medal of Freedom.
