Passage Summary: There are three rules for snow: you have 24 hours to clear it, after 24 hours the city might do it and send you a bill, and after 48 hours you get a ticket unless you have a good reason.

Reasoning: Landowners must clear snow within 24 hours; the city can clear it and bill the owner after 24 hours; and owners face fines after 48 hours unless they have an excuse.

Analysis: In a 'Must be True' scenario, we must strictly follow the logic of the provided rules without adding our own. Note the gap between the 24-hour and 48-hour marks: the city can bill you for clearing snow as early as the 25th hour, but you don't get a citation (fine) until after the 48th hour. Therefore, it is possible for a landowner to be billed for city snow removal without ever receiving a fine. Look for an answer that stays within these specific temporal boundaries.
