Which two parts of the plot take place in acts one and two of macbeth

In Act I and Act II of Macbeth, the exposition and rising action take place.

Explanation:

In Macbeth, Shakespeare tells a story of a man who is informed by the three witches that he would become a king. After hearing their prophecy, he makes a plan to kill King Duncan so that he can assume the throne.

When the characters of Banquo, Macbeth, Duncan and the three witches are introduced, the exposition takes place. The exposition is a literary device that provides background information or context, and introduces the characters.

The rising action starts when Macbeth begins to consider killing Duncan after hearing the witches' prophecy. The rising action is a part of the plot that occurs immediately after the exposition, builds up tension and leads to a conflict. The crucial moment of the rising action is when Macbeth murders Duncan.
