Luckily I noticed -.- ; My grandparents had gone out for Sunday lunch and I ' m practically oblivious to everything but what 's in front of me . I think my reaction was rather robotic :/ I just looked at the smoke , picked up the dog 's water bowl that 's by the back door and just poured it over it . That was it .

Question: What caused the pouring of the dog 's bowl ?
Answer: a candle , that was left on , set fire to a curtain .a plant needing watering because it almost died .None of the above choices .the dog was parched and needed the water .
