A can be removed because it is not talking about politics like the question asked. B can be removed because the essay does not speak of politics. I decide to remove D because after reading it, the text does not mention how newspapers develop over time. Instead, it talks about how newspapers were made and how throughout different areas. This leads to answer choice C, which truthfully claims that the author focuses on the technology (in this case, it simply means tools or items) used to make different types of newspapers.
Hopefully, this helped. if you have any questions, please dont hesitate to ask !
Note that, even though the mission is almost impossible, the character "<em>never gives up trying</em>" to accomplish it, which means that "Never give up" is the theme of the story.
