Tense agreement for multiple clauses

0 I'm confused with tense agreement across clauses of a sentence. Should all the tenses match or is it ok to mismatch?02br

004 seems wrong, but the others sound reasonable to me. My interpretation is a sentence like 1 or 5 indicates that the secondary fact may still be true while the structure in 2 and 6 indicates it is likely not true anymore.0-
