In the story, it was the time of the Night or Rebirth when all creatures diet. The moon changes from young and beautiful(she was described as mesmerizing and luminescent) to old and weak(she became a sprinkle of sparkling dust, or the title "embers of moonlight" itself)
The answer is C. Weedon always makes sure White Fang is fed
Weedon offers White Fang meat when they are introduced. Although White Fang does not take the meat directly from Weedon's hand at first. He eventually starts to eat out of his hand and their bond strengthened. So the answer is C.
Hope this helped. Have a great day!
Personally, I would say that "The city is so big" best captures life in the city, because it describes how busy the city is, and how everything happens so fast it just rushes by. It explains that even people get lost in the wonder and chaos of the city, disappearing into life.
