I would say that all 6 are correct. For some reason, #2 is a bit strange for me, but it follows the same pattern as #4 and #6. Hmmm.Originally Posted by navi
Are these sentences correct:
1-What you are doing is important.
2-It is important what you are doing.
3-Which books are studied in the course is important.
4-It is important which books are studied in the course.
5-Who said those words is important.
6-It is important who said those words.
I agree with Mike and can't put my finger on why either.
