Here's why:
* Early Career: Shakespeare's career began around 1592, but his early plays are often debated among scholars.
* Dating Challenges: There's limited evidence, like printing dates or references to events, to accurately date many of his works.
* Collaboration: It's likely Shakespeare collaborated with other playwrights, making attributions even more difficult.
However, here are three plays that *could* have been written during this period, based on scholarly speculation and evidence:
1. Henry VI, Part 2: Some scholars believe it was written around 1591-1592, but this is still debated.
2. Titus Andronicus: This play is often considered Shakespeare's earliest work, possibly written in the late 1580s or early 1590s. However, there is still debate about its authorship.
3. The Comedy of Errors: This play is often speculated to have been written in the late 1580s, but again, there's no concrete evidence.
Remember, these are just possibilities based on scholarly discussions. There's no definitive answer to your question.
