Read the following passage and answer the question. When Lily first arrived at university, she expected her evenings to be free after classes. Instead, she discovered that learning at university demands far more self-discipline than high school ever did. Lectures provide only a starting point; professors expect students to spend at least two additional hours reviewing notes and reading sources for every hour in class. At first, Lily struggled because she treated study time as something leftover, scheduled only when nothing else was happening. Her grades in the first term reflected this habit. During the winter break, she made a simple change: she wrote fixed study blocks into her weekly plan, treating them as firmly as appointments with a doctor. By treating scheduled study as non-negotiable rather than optional, she gradually caught up, and her second-term results improved noticeably. What changed was not her intelligence or her workload, but the way she ordered her priorities. Question: What can be inferred from the passage about Lily's improvement in the second term? A) She reduced her total workload to make studying easier. B) Her professors gave her extra lessons during the winter break. C) She succeeded because she began treating study time as fixed and non-negotiable. D) She was naturally more intelligent in the second term than in the first.
