(10) The advice was in the form of sayings, such as, “Early to bed and early to rise, makes a man healthy, wealthy, and wise.” Which is the most effective way to combine sentences 2 and 3? There two popular periodicals, the Philadelphia Gazette and Poor Richard’s, he published. There he published the Philadelphia Gazette and Poor Richard’s that were two popular periodicals. There he published two popular periodicals, the Philadelphia Gazette and Poor Richard’s.

Answer 1

The answer is: There he published two popular periodicals, the Philadelphia Gazette and Poor Richard’s
The fact that Benjamin Franklin own the publisher already mentioned in sentence 1, and will be redundant if it mentioned again in sentence 2&3,  so option A is wrong.  Option 2 is simply too awkward too read. It would be a good sentence if option 2 change the word 'that' into 'both'
