Hello. It says that "The answers may be found in the exercises preceding". There are two relevant sentences from the exercises. "The farmers' daughters do labor" or "the farmer's daughter labors". If it was the second, daughter, being the subject, would be filia in the question. As it is filiae, assume it's daughters (plural), referring to the first sentence, farmers' daughters do labor.<br /><br />So the answer would probably be "Filiae agricolarum laborant". (Also in your answer filiae and laborant should stay the same, not changed to filia and laborat).<br /><br />Of course I don't know much more than you. Blind leading the blind, eh?
