I'm a native speaker but I can't remember this rule!
So would the proper sentence be the first or the second one? They both sound wrong to me!
1. Have the industrial revolution and its consequences been a disaster for the human race?
2. Has the industrial revolution and its consequences been a disaster for the human race?
Basically it comes down to whether the subject is considered plural or singular, right? If so, I would think the first one is correct. I think when it's phrased as a question I get thrown off.
