一道assumption类型题目，求助！！！

For several years, Nighttime News attracted fewer viewers than World News,
which broadcasts its show at the same time as Nighttime Ne~ Recently,
the producers of Nighttime News added personal interests tQd~ and
increased coverage of sports and weather. The two programs now have a
roughly equal number of viewers. Clearly, the recent programming changes
persuaded viewers to switch from World News to Nighttime News.
Which of the following is an assumption on which the author relies?
(A) Viewers are more interested in sports and weather than in personal
interest stories.
(B) The programming content of Nighttime News is more closely aligned with
the interests of the overall audience than is the content of World News.
(C) Some World News viewers liked the new Nighttime News programming
better than they liked the World News programming.
(0) There are other possible causes for an increase in the number of viewers
of Nighttime News, including a recent ad campaign that aired on many
local affiliates.
(E) The quality of World News will remain constant even if Nighttime News
improves.
答案是C，有点意外，B为什么不对？我个人选的是E，但后来发现时态不会，will讨论的是将来，如果去掉will ，E应该没问题，现在就是B,C两个选项，如何排除B，而且C中的"some"没有说服力，一些人的喜好不能解释shift,求助！！！

B要是对，大家就都看NIGHTTIME NEWS了，不会EQUAL

C的SOME是
SOME喜欢 新 NIGHTTIME，所以SWITCH，对啊

取非：没有喜欢新NIGHTTIME，那谁来SWITCH？削弱

这个题目tricky的地方在，把C取非，不是some World News viewers didn't like, 而是NO World News viewers liked the new Nighttime News programming。。。 取非以后题干就推不出来了，所以选C。 我也没明白B为什么不对

官方给的解释是The choice B tells us something about how the broadcasts are
catering to the interests of the audience, but it does not discuss whether the content
changes would specifically drive viewers from World News to Nighttime News. However,
the conclusion hinges on this issue of switching.  我理解的就是这个assumption要和文章结论相连，可是B选项只说了电视内容怎么怎么样，没紧扣“人们换了电视节目”这个结论，所以不选。

I think Cheleeea's explanation is very precise
