Switch Plates

So my landlord was just by a few days ago, because all the lights in the East end of the house were not working. It was quite a puzzle to me, as the outlets still worked, and I had already tried flipping the breaker to no avail. However it turned out to be a loose wire in one of the other outlets. While he was here he also replaced one of the outlets as well as a couple of the switch plates. They don’t match everything else color wise, but then who really cares in a place like this?
