an order of execution by the king.

Macbeth's first act includes an invasion by another country, an order of execution by the king, and treacherous plotting. However, it does not include a cold-blooded, premeditated murder.

To determine the answer to this question, we need to analyze the options given and cross-reference them with the events that take place in Act 1 of William Shakespeare's play Macbeth.

1. An invasion by another country: In Act 1, there is no mention or depiction of any invasion by another country. Macbeth primarily revolves around the internal struggles and ambitions of its characters, rather than external conflicts.

2. An order of execution by the king: In Act 1, King Duncan is alive and well. There is no order of execution by him or any other character. The act focuses on setting up the events that lead to Duncan's murder later in the play.

3. A cold-blooded, premeditated murder: This option is accurate. In Act 1, Macbeth and his wife, Lady Macbeth, conspire and carry out the murder of King Duncan. This act marks a turning point for the characters and sets the stage for the rest of the play.

4. Some treacherous plotting: This option is also accurate. Throughout Act 1, there is a significant amount of treacherous plotting taking place. Macbeth and Lady Macbeth devise a plan to murder King Duncan and secure the throne for themselves. They discuss their intentions and make arrangements for the crime.

Based on this analysis, the answer to the question is "an invasion by another country," as this event does not occur in Act 1 of Macbeth.
