Hello Guys, newbie here.
I came across this question while practicing Manhattan SC.
Correct this sentence
"It is possible that the earthquake may have been casual to the building's collapse."
Answer
"it is possible that the earthquake have caused to the building's collapse"
The answer was clear for me about redundancy.
But my question is why this sentence use
"the earthquake have caused"
instead of
"the earthquake has caused"
I think you either copied the right answer incorrectly, or you have a copy of the book with an error. The right answer should read something like "The earthquake may have caused the building's collapse." Can you post a screenshot or a photo of the exact problem you're doing so I can look into it?
"The earthquake have caused ________" is always incorrect, as you suspected. The problem is with subject/verb agreement.
However, "The earthquake may have caused _______" is correct, because of what the other posters mentioned about the subjunctive.
Also, the phrase "may have caused
to the building's collapse" is incorrect - you don't need to use 'to' with that phrase.
