A. An expert on this task can do it in a more perfect way.
B. Had I known it before, 1 would have taken corrective measures.
C. No one really wants to face such a series of unfortunate events in life.
D. The contest judges were asked to pick out the essays that showed the most originality.
Explanation: Perfect এর আগে more use করা Incorrect. এখানে ভুল বাক্যটি হলো 'An expert on this task can do it in a more perfect way.'। 'Perfect' শব্দটি নিজেই চরম একটি গুণ বোঝায়, তাই এর সাথে 'more' ব্যবহার করা অপ্রয়োজনীয়। সঠিক বাক্যটি হবে 'An expert on this task can do it in a perfect way' অথবা 'An expert on this task can do it in a more complete way'।
