"Ten strom není malý, ale velký."

Translation: The tree is not small but big.

[EinatAdar]

You mostly have 'ten' as that. Why is it The?

[VladaFu]

We have both the and that for ten throughout the course consistently.

Other correct answer: The tree isn't small, but is big

[tatka_]

I don't agree. Translate for your sentence is "Ten strom není malý, ale JE velký."

[Fabiola-609]

That would translate "The tree is not small, but it is big"

Just use the report function for other correct answers ;-)

Why not "this tree"

[tatka_]

There is a difference between "this" and "the/that". For "this" (as adjective) we can use "tento / tato / toto / tenhle / tahle / tohle".
