consider the following example sentence:
This section summarizes Tom and Jerry's 1975 experimental designs and results and reviews their comparisons of the behavior they observed with the predictions of Yosemite Sam.
Should there be a comma before the bolded and?
I ask because If "designs and results" was just "designs" I would not put a comma (the sentence is clear without it, and I believe the part of the sentence after the bolded and is not an independent clause?).
However, in sentences such as this I often want to put a comma to distinguish the ands. Specifically, I see the first and as as having to do with "summarizes" and the second and as having to do with "this section". I feel like without a comma this may not be clear?
I know there are many questions on this topic, but I was unsure of what keywords to use to find a topic search similar to this example.
If someone has a better title suggestion please let me know.
