I've been taking Spanish lessons through Duolingo and came across a question where a girl says "I sleep alone and eat alone." and you are asked to select the options for which is correct. It gave two answers that it says are correct:
- "Yo duermo sola y como sola." <-- I chose this one.
- "Yo duermo solo y como solo." <-- but this one was also listed as correct
Can either gender properly say either of those statements? Or should feminine/masculine speakers use their appropriate adjectives?
