  "Find what fraction of the novel she has read by end of Sunday. Then divide the remaining fraction by 1/9 to find how many days from Monday.",
  "Read so far: 1/5 + 1/4 = 4/20 + 5/20 = 9/20. Remaining: 11/20. Days needed: (11/20) / (1/9) = 11/20 x 9 = 99/20 = 4.95 days from Monday.",
  "4 full days (Mon-Thu) reads 4/9 more = 80/180. Total = 81/180 + 80/180 = 161/180. Friday she reads the last 19/180 and finishes. Answer: Friday (option A)."
