Subject verb agreement- The cup of tea and dessert come/comes with this set of meal. Which is correct?.?

Strangely, you can use both in this instance. It depends on whether you think the 'and' makes 'tea and dessert' a collective noun, or if you view them as separate things. No one would think you were wrong to say either, but personally I would go with 'come' as it is more strictly correct - the tea and dessert are two different things.

Hope this helps :)

The cup of tea and the dessert are separate items and together are plural so you use the plural verb.

The cup of tea and dessert come with this meal.

You do not need to put in 'set of meal' as a meal is already a combination of food items. (ie it is already a set)

I disagree with you. A native English speaker would say:

A beverage and dessert ARE included.

Tea and dessert ARE included.

And definitely:

The cup of tea and dessert [these two specific items] COME with the meal.

This is a quirk of English grammar.

We'd say: "The cup of tea comes with the meal."

Two objects make a plural entity.

Compare: "Two cups of tea come with the meal."

The book is right. Substitute "they" and read it again.

You are right, it should be "comes".
