Most sci-fi movies released in the past few years have not performed commercially. To address this, scriptwriters need to develop better impressions about the possible future world by reading popular science fiction & even some futuristic science papers. Scriptwriters can then write plots that are more acceptable to general public.
The argument assumes that
A) The possibility shown in plots from popular science fiction are very different from those proposed in futuristic science papers
B) acceptable plot is most crucial factor that decides success of a science fiction movie
C) Making the plot more acceptable to general public shall increase the viewership of the movie
D) acceptable plots are only available in popular science fiction & futuristic science papers
E) all popular sci-fi fiction movies have acceptable plots.
Assumption is something that makes the premise intend to the conclusion.
P+A->C
Here the premise talks about sci-fi movies not doing well
commercially. So we need to assume something that will help us reach to conclusion on why scriptwriters need to write more acceptable plots to make it a commercial success. So the focus is not acceptable plots, rather its the commercial success.
writers read popular science fiction & some futuristic science papers -> Acceptable plots -> Commercial success.
(Intermediate Conclusion) (conclusion)
And in the options only
option C talks about increase in commercial valuation(by increase in viewership)
