邏輯上The Olympic Games不會proclaiming a sacred truce during the festival’s month 而且proclaiming a sacred truce during the festival’s month也不可能是The Olympic Games helped to keep peace among the pugnacious states of the Greek world的隨伴結果. 所以B不可能對. 我們不知道是誰proclaiming a sacred truce, 可是B像在說是The Olympic Games在proclaiming a sacred truce, 所以OG說it is unclear who is proclaiming. 也因為這樣correct choice D用了被動(因為不知道誰在proclaim)
