"This is not good bread."

Translation: To není dobrý chléb.

[ZaronSmith]

Why is it wrong to say "není to ..." here?

[kacenka9]

Nothing. But you are the very first to comment on it. No submissions were made on that before

[OndraSl]

As kacenka9 said, "Není to dobrý chléb." is perfectly acceptable answer and you shouldn't be worried.

In other exercises Duo uses for translate "this" = "toto/tohle". Why the sentence is translated as "TO není dobrý chléb" and does not accept "TOTO není dobrý chléb" ?
