please tell whether potato is countable or not?

[Kwfine]

Hi all!

My friends and I are stuck over a question from an assorted english workbook.
Here is the question we are suffering from:

Q1:
there/is/are/a lot of/many/some/potato/potatoes/in the garden.

Here is an answer we come up with:
A1: There are a lot of potates in the garden.

Please help clarify!

These are the answers:

There are a lot of/many/some potatoes in the garden.

Potatoes are countable until they have been mashed or otherwise incorporated into a meal and no longer resemble individual vegetables.

You're right: she's wrong.

Of course, few things are really wrong in English-- we often say There's rather than There're because it is easier to pronounce:

"There's seven sandwiches in the fridge for you."
