I just started with the D'Ooge method this weekend, although I have previously (briefly) studied Latin with the French Assimil method.
I have two (very basic) questions garding the keys:
-In paragraph 22, page 13 of the book, exercise 6:
Rosam in comis habet.
The key says that the predicate is "in comis habet", yet as Rosam is the direct object, shouldn't the whole sentence be a predicate (and the subject is merely implied in the verb)?
-In paragraph 40, page 19, exercise 6:
Translate: Cuius filiae laborant
I thought Cuius is singular (as stated in the book p. 283). In that case shouldn't the reply to the question be Filiae agricolae laborant, instead of Filiae agricolarum laborant (as stated in the Key)?
