I appreciate that explanation. It's my ambition to learn to communicate in Polish and to some degree I will, but my grammatical knowledge of English let alone Polish is not good at all. So I never question the comments about masculine and other various types of the same word, but I do read the comments and sometimes disagreement between people. Very nice helpful course
"Tamto" is 'that, that one' for neuter. "Tamtego" is Genitive either for neuter or masculine (which is "tamten").
We rarely use these words for "that", unless we want to emphasize the contrast between "this" and "that". This is why we usually accept both 'this' and 'that' for simple 'ten/ta/to'.
We can also use it when 'that' is really somewhere not close to us. Here I don't think there's any reason not to use simple "to", I believe "tamto" is here in the original sentence just to teach you that we do have direct translations for "that".
If I'm not mistaken, "czy" is optional on questions. You may elaborate questions with the exact same structure you would use for affirmations, you simply add the question mark (and change the intonation when speaking, of course). It's the same in my mother language (spanish). Hope I could help. :)
No, ć is like... kinda like softened T. It's rendered by ть in Russian.
