"Because they gave everything to you."
Translation:Protože všechno dali tobě.
I'm trying to imagine a context where that would work... and not succeeding.
If we don't need to stress "you", we use the short form "ti": "Protože ti dali všechno" or "Protože ti všechno dali".
The long form "tobě" is stressed and as such it goes to the end: "Protože dali všechno tobě".
Well, some of our discussions, especially https://forum.duolingo.com/comment/31466920 and https://forum.duolingo.com/comment/38369227/Ordering-the-Czech-clitics-Intermediate-2020-05-04 and also https://ufal.mff.cuni.cz/~hana/bib/hana-diss-ch4.pdf where table 4.2 on page 77 shows ti and tobě and many other words and shows which can be used in the weak position and which in the strong position (but I think jej and je mentioned there are also possible in the strong position).
And I wrote something about topic and comment/focus yesterday: https://forum.duolingo.com/comment/31101147 (bottom of the page)
Regarding "ti/tě" and "tebe/tobě" - you have to use the long form after prepositions, but without prepositions the short form is default/neutral and clitic (second position), while the long form is emphatic/stressed and is placed at the beginning (topic) or end (comment/focus).
