Which word can be used? (domain, area, forte) And I also want to know what the differences are among three pairs. 1.The care of the elderly is being placed firmly within the area/domain of the family. 2.Physics used to be very much a male area/domain. 3.His sister is the physics expert in the family, but literature is his domain/forte(I want to say what he's very good at literature in one word between 'domain' and 'forte').
