[Grammar] about conditionals

[murattopak]

Information
The forecast is that the weather will stay dry, but only heavy rain can avert the crisis.

If it doesn't rain, ....

the crisis cannot/won't be averted.

Bold one is corrrect according to answer key. Is there any chance of my answer? If not, could you explain why it's not possible to use "can" there?


Information
The goverments involved didn't take positive action after the 1997 crisis. Environmentalists think this is why the current crisis has happened.

If the governments involved had taken positive action after the 1997 crisis, the current crisis wouldn't have happened/happen.

I thought that the consequences was related to present, so I decided to make it mixed conditional.

Thanks in advance for your help.

I am not a teacher.

It seems you are talking about two different crises, or the same crisis seen from two different time perspectives.

Part one is about a possible future crisis that can still be averted if it rains.
"the crisis won't be averted..." is natural because it is in the future tense.

Part two is about a crisis that has already happened.
If some positive action had not been taken, then the crisis wouldn't have happened, but it did.
