How are fact-checking and knowledge-based journalism different?

Linda Greenhouse, recipient of the Pulitzer Prize, claims journalists should be as promising as possible with their sources and practices. Greenhouse: We live in a "expanding reality" era in which everyone talks about a topic with sensitivity. The truth should be checked twice, she claims.

Choice A and C is out instantly- the topic is already clear (having growth epxeriences) and the sentence 3 is boring doesn't make much an improvement (in my opinion).

I chose B over D because you don't really have to know the film name. Adding details of a future goal in sentence 2 can tell us how the growth experience helped with the goal.
