### User's Query:
Please give the title of the work of Shakespeare that has the most characters.

### Extra Knowledge:
most characters refers to max(count(character_id))
SELECT T.Title FROM ( SELECT T1.Title, COUNT(T3.character_id) AS num FROM works T1 INNER JOIN chapters T2 ON T1.id = T2.work_id INNER JOIN paragraphs T3 ON T2.id = T3.chapter_id INNER JOIN characters T4 ON T3.character_id = T4.id GROUP BY T3.character_id, T1.Title ) T ORDER BY T.num DESC LIMIT 1
