Critical Reasoning

The local board of education found that, because the current physics curriculum has little direct relevance
to today's world, physics classes attracted few high school students. So to attract students to physics classes,
the board proposed a curriculum that emphasizes principles of physics involved in producing and analyzing
visual images.
Which of the following, if true, provides the strongest reason to expect that the proposed curriculum will be
successful in attracting students?
(A) Several of the fundamental principles of physics are involved in producing and analyzing visual images.
(B) Knowledge of physics is becoming increasingly important in understanding the technology used in today's
world.
(C) Equipment that a large producer of photographic equipment has donated to the high school could be used
in the proposed curriculum.
(D) The number of students interested in physics today is much lower than the number of students interested
in physics 50 years ago.
(E) In today's world the production and analysis of visual images is of major importance in communications,
business, and recreation.

Can some one enlighten it..

Cause and Effect:

Image curriculum will attract more student.

IMO: E looks promising to me.

OA is E

but which is the main point of topic ; knowledge of physics or the visual images.

+1 for E.
Always check for something that has a bearing on the conclusion .

we need to look for an option that shows the direct relevance of visual images in today's world. Only E is doing that.
