Hi,
An example is
What led him to resign his office?
Any advices?
That should read 'Any advice'.
it sounds like a reasonable guideline, if you include some lower vertebrates:
What led your python to eat my chihuahua?
Thanks.
You said 'a reasonable guideline' but is it a rule or not?
I don't know-- I'd have to see all the possibilities. You can lead a horse to water, but you can't make him drink.
You also said 'Vertebrates'. Not only that I think. It can be OK for that 'I lead the flower pot to drop', can't it? Any advice?
More advices?
