    in my openion the correct answer of the first question is incorrect. Because;
    question 1: How did the researchers gather the cough recordings used in the experiment?
    correct answer : From volunteers taking part in the research

    The researchers got the cough recordings from volunteers who sent them through computers or mobile devices.
    the article does not include the word ''volunteers''
