The first sentence is punctuated correctly:
"I baked many items for the bake sale: banana and blueberry muffins; chocolate and lemon cupcakes; and blackberry and cherry pie."
The other sentences have punctuation issues:
-
The second sentence does not need a colon. It should be: "For my birthday I received a new bike that I plan to use in a race next month and a gift card to the local bookstore."
-
The third sentence needs a different structure. It could be written as: "The club can meet in one of these locations: the gym, the library, or the cafeteria."
-
The fourth sentence has an unnecessary colon before the list. It should be: "My favorite foods are pizza with ham and pineapple and lasagna."
