The following excerpt from a fictitious science news report discusses a fictitious type of location called a Morefa.

For zoologists studying the behavior of certain species of birds, the critical importance of observing the birds in those species' morefa during the annual breeding season is obvious. Such observation allows researchers to study not only the courtship displays of many different individuals within a species, but also the species' social hierarchy. Moreover, since some species repeatedly return to the same morefa, researchers can study changes in group dynamics from year to year. The value of observing a morefa when the birds are not present, however -- such as prior to their arrival or after they have abandoned the area to establish their nests -- is only now becoming apparent.

Based on the definition of the imaginary word morefa that can be inferred from the previous paragraph, which of the following activities of a bird species must happen in a location for that location to be the species' morefa, and which must NOT happen in a location for that location to be the species' morefa? Make only two selections, one in each column.

Option C - Establishing nets must not happen in the location since they leave the location to build nests
Option D - Must happen since as per passage info it is the place where many individuals of species interact for mating and exhibit social structure

I think
must happen - D (because birds need to gather within their own species for courtship displays)
must not happen - E (because if there is territorial competition, birds will not return to the same place and data wont be accurate for year on year)
