Ten new television shows appeared in September. Five were sitcoms, three hour-long dramas, and two news shows. By January, only seven shows remained. Five of the remaining were sitcoms.

1. Only one of the news-magazine shows remained on the air
2. Only one of the hour-long dramas remained on the air
3. At least one of the cancelled shows was a drama
4. Television viewers prefer sitcoms over dramas

This statistics-based question requires analyzing the show distribution: with 5 sitcoms remaining from 5 original, and only 2 of 3 dramas remaining, option B is mathematically correct.
