There's no cost to Mark and he views this as a good cause so he signs the petition. One week later Mark gets a postcard in the mail saying "Alex's Stop$-$n$-$Shop has been a family$-$operated, locally owned business for a decade. Come in this weekend and help us celebrate our $10$ year anniversary. Thank you for supporting locally owned businesses in our community."

C$.$ It's not likely that such a small action $($signing a petition$)$ will actually affect whether or not Mark attends the event at Alex's store.

D$.$ All of the above are Correct

E$.$ A and B are Correct but C is Incorrect
