* "There is bread and milk" is grammatically correct. Here's why:
* "There is" agrees with the closest noun to it, which is "bread" (singular).
* Although "milk" is also uncountable, the verb "is" focuses on the singular "bread."
* "There are bread and milk" is grammatically incorrect because it tries to match the verb ("are") with two uncountable nouns.
Here are some ways to correct the second sentence:
* "There is bread and milk." (as explained above)
* "There are some bread and some milk." (using quantifiers)
* "There is some bread and some milk." (using quantifiers)
Key Point: When dealing with uncountable nouns, the verb's agreement depends on the closest noun to the verb.
