  1. I am unable to get a new set of MCQs. Even after refreshing the page I keep getting the same MCQs that I have already attempted

  2. I didn’t get the last MCQ. Like how can be waving your hand be a form of wave?
    And why can’t it be 1&4 because when you throw a stone, it would bang the window and would produce sound waves and shouting is also a kind of sound wave
