How can we build syntax trees for sentences with enumerations?
I have three sentences as examples:
S1: John, Mary, Paul, Alice and Bob eat a cake.
S2: I'm eating an apple, a pear, a cherry, a strawberry and a banana.
S3: I'm working, eating, drinking and sleeping every day.
I'm a beginner in generative grammar. I've learned a bit about X-Bar theory, and it seems to me that all the syntax trees are binary trees (no more than two children for each node). In this context, I couldn't find any way to arrange the terms of an enumeration in such a binary tree.
