Final answer:
The provided information is insufficient to list the events in Category 1 without access to the specific chapter or resource that organizes events into categories.
Step-by-step explanation:
The question asks to list the four events grouped in Category 1. However, given the provided information, it is not possible to determine specifically which events are included in Category 1 as the reference to events seems to be from a specific text or resource that is not provided. To properly list the events in the said category, access to the chapter or resource that lists these events under various categories is necessary.
