Answer choice C- first title

Hi Shafieiava, thanks for the question! The reason that answer choice C's title for the first passage is apt is because the first passage discusses the different issues that have arisen as a result of people and companies being allowed to patent the obvious. Answer choice A might be tempting as far as its title for passage A, however the second title (passage B's) is not correct. Answer choice B does not correctly characterize passage B. Answer choice D does not correctly characterize passage A because passage A was not concerned about describing a misunderstanding of the patent system. Lastly, answer choice E takes the detergent component of passage A and makes it seem like that was the whole point. In fact the deterrent idea came from the fact that companies are allowed to patent the obvious. I hope this helps. Please let me know if you have any other questions.
