I think that the term that describes the reporter's activity in this story is A: <u>Gatekeeping.</u>
Explanation:
The reporter's job, according to this excerpt, is to keep an eye on new facts about different subjects in order to inform the readers about them. In this case, she is aware of a new scientific study on tool use in Armenian box turtles and she writes about it in an article that her boss asks her to make shorter. So, the word that best describes her activity is <em>gatekeeping</em> beacuse she has to be very aware of the new things that may interest the society.
