Hello. You did not provide the answer options or the purpose of John with this text. This makes it impossible for your question to be answered accurately. However, I will try to help you in any way possible.
If John's goal is to present how informative newspapers are and how they present consistent and reliable information, he can use a question like "Which newspapers are most effective in informing the public?" so he is able to limit the topic to just informational newspapers. However, if John wants to address the manufacture or distribution of newspapers, he can use questions such as:
"What are the stages of production of the newspaper?", "" What is the best frequency of distribution of the newspaper? ", Among others.
