9. Unless Shelly had read him wrong, Jack would find /would have found her unorthodox approach irresistible.

{"correct_option"=>"would have found", "explanation"=>"This is a type 3 conditional sentence, referring to an unreal past situation and its consequence. The structure is 'If + past perfect, would + have + past participle'. 'Unless Shelly had read him wrong' implies that the reading might or might not have been correct, thus 'would have found' is the correct choice."}
