Question

Hey guys. I need help with comma rule
Rock climbing and scuba diving are two type of avicii's favorite activities. Where do I put the comma

Answer 1

I would say it should be written as "Rock climbing, and scuba diving, are two of Avicii's favorite activities."

Answer 2

"Rock climbing, and scuba diving are two of Avicii's favorite activities." maybe?

Answer 3

Technically speaking, a comma doesn't belong anywhere in this sentence. Since there are only two activities listed in the sentence, the original is fine as it is. If there was another activity though, you would need to place commas after each activity. For example, "Rock climbing, scuba diving, and hiking were some of Avicii's favorite activities," would be proper comma rule. In this sentence, commas would only be needed to separate words in a sentence with three or more items.
