I agree partially with Sara's logic, except that most native English speakers would also put "an" before the word apple, i.e. "There is an apple and bread", however "an" was not in the word list
your English is faulty. Since there are two objects, namely apple and bread, you need a plural verb, namely "are" not the singular "is".
Since "bread" is a non-countable noun, and "apple" is singular, most native English speakers are going to use "is" here. Technically, yes, there are multiple objects, but "there is" as a phrase is going to take precedence over verb-predicate agreement. However, if there were multiple apples, it would be "there are." Just a quirk of the language!
How are we supposed to know apple is sigular here? Couldnt this mean some apple? Wouldn't a bunch of slices of apple also be תפוח?
