Hi - i am doing english SAT practice and have a few grammar questions.
1. '60s flower child
Book says an apostrophe goes before 60. Can you explain why?
2. Helen is a bright, friendly, confident girl.
Book says this is correct Why is the word "and" not before confident. I think it should read Helen is a bright, friendly, and confident girl. Can you expalin why there is no "and"
1. '60s is an abbreviated form of 1960s.
2. It's not necessary to use "and" in this sentence.
