My grammer book (Heim '82) has the following exercise. Insert the correct form of the demonstrative pronoun: 1. Kolika ____ Cechum volate? (C's are with č, u = ů). 2. Kolik ____ Cechu volate? I read that dependant nouns with kolik take case 2. (genitive) however, there are different meanings of volat depending on whether it is used in the dative (3) or accusative (2). In the first instance above, 'Cechum' appears dative but Kolika requires genitive, which governs? In the second, Cechu is genitive but kolik is a direct case. What are the translations and proper pronouns? Thanks for the help.
