Dear teachers,

If I want to use so that to express purpose, sould I say:

a) He refused to move so that the police had to carry him away.

b) He refused to move so that the police would have to carry him away.

c) both possible ?

Thank you for your help.
Best regards,
Hela

Both possible, but I don't particularly care for the structure-- it confuses purpose with result.

b) expresses purpose better.

The following expresses result better.

He refused to move; so the police had to carry him away. (where "so" = "therefore")

"so that" used to express purpose typically has a modal ("will", "can", "would", "could", etc.)
