Translation:They have to go to jail because their companies evade tax.
'have to go to jail' as shown. I chose 'must be jailed' Do they not sound pretty similar in meaning. Can you point out the difference?
They have to go to jail = they're forced to go to jail, the main verb here is to GO.
They must be jailed = they must be put into jail, the main verb here is to be JAILed.
It's subtly different.
