I entered "Things are more difficult now", but was marked wrong. Shouldn't this be considered a correct answer. If not, can someone tell me why? I would think "Things are more difficult now" conveys the same idea as "Now, things are more difficult", one of the solutions presented as correct by Duolingo. Shouldn't both be considered correct? Thanks :-)
Son is used as a definition... A description that defines the noun. Estar is used for description that doesn't define the noun, something variable. Things are not defined as difficult or easy. Use están. At the same time, my hair is blond and if i dye it red tomorrow, I still use ser (soy) to say i am a blonde/i am a redhead. Does that help with the clarification of temporary/permanent vs defining characteristic/variable characteristic?
