Question

Which sentence correctly uses the semicolon?

Answer 1

I think its 'We had it worse than everyone on the first floor,all the windows in all the upstairs rooms were tinted; and there wasn't enough moonlight in the first place.'

Answer 2

Answer:

(It had been a most unpleasant coincidence that the power outage had come when we had guests staying over; the entire house was full.)

Explanation:

The sentences are sematically linked, so the semicolon is connecting the two sentences coherently.  This means that the semicolon can be replaced by a connector: It had been a most unpleasant coincidence that the power outage had come when we had guests staying over since  the entire house was full. The coherence is related to a known or evident reason.
