This question here was rightly closed as a duplicate:
It has currently been linked to the following three other questions:
Should I say "there is a handful of..." or "there are a handful of...."?
"There is a lot of food and fruit" vs. "there are a lot of food and fruit"
"There Is"/"There are" depends on plurality of the first list element or not?
These appear in a different order on the original page. Now my feeling is that numbers (1) and (2) here are about Determiners and mass nouns. The Determiners in these examples have an impact on whether we see plural or singular verb inflection. Another main issue is the mass nouns involved. The coordination is a supplementary issue in only one of the questions and not a main concern of either of these questions or answers.
In contrast, the third question is a genuine duplicate because the main issue in these two questions is the coordination appearing as the Complement of the verb BE. Can we change the links so that the question is only linked to number (3), please? It would reduce the spagetti junction of question links and also provide a more reliable final landing page for readers.
