What are the differences between these four sentences:
(1) Things have been pretty smooth until yesterday
(2) Things had been pretty smooth until yesterday
(3) Things were pretty smooth until yesterday
(4) Things are pretty smooth until yesterday (it is Wrong)
I am sorry. I was writing (1) but then I noticed "yesterday" in the sentence,
and it made me confused. I am not sure whether (1) or (2) or (3) is correct
