In reply to your question below about the active voice and the passive voice, and whether this makes a difference when considering whether something's an event: short answer: no.

Slightly longer answer, I don't think that we can rely on voice being translated literally and consistently enough to depend on it too much. Also, it really doesn't matter. If you can restate something in the passive in the active and you think it should be an event, than the voice doesn't matter. If you don't think it should be an event, than that should be true whether it's active or passive.

A general principle to sum up: consideration of whether something is an event should happen at several removes from any particular bit of text.

Did that help?
