I think its D? I don't think its A because just because people attend concerts once in while, doesn't show effectively how much the classmates listen to, on average, each day. I don't think its B because some people might not know how long they listen to music each day, and plus, its not efficient to ask each person manually. I don't think its C because you might not see them listening to music at least sometimes, so it wouldn't be very accurate. So, by process of elimination, I think its D...
Hope this helps.
Answer:
<u>Would the Wright brothers' first powered airplane have been successful if they had chosen other materials?</u>
Explanation:
<em>Remember,</em> Noni wants a research question that is more complex; meaning one that requires giving careful thought and explanation.
Rather than just asking what the Wright brothers used to make their first plane, asking, Would the Wright brothers' first powered airplane have been successful if they had chosen other materials? provides a measure of complexity since it requires first knowing what they use, before exploring whether they would be successful if they had chosen other materials.
