In close relationships: 1. positive events have greater psychological impact than negative events do. 2. positive and negative events have roughly the same impact. 3. negative events have greater psychological impact than positive events do. 4. positive events have greater impact in the early stages of relationships, but negative events have greater impact later on.

The correct answer is C. negative events have a great psychological impact than positive events.
