Answer the question depending on the context.
Context: More than half of habitat for listed species is on non-federal property, owned by citizens, states, local governments, tribal governments and private organizations. Before the law was amended in 1982, a listed species could be taken only for scientific or research purposes. The amendment created a permit process to circumvent the take prohibition called a Habitat Conservation Plan or HCP to give incentives to non-federal land managers and private landowners to help protect listed and unlisted species, while allowing economic development that may harm ("take") the species.;
Question: Before the amendment in 1982, under what situations could a listed species be displaced?;
If you can't find the answer, please respond "unanswerable".
Answer:
only for scientific or research purposes
The text states that before 1982, a listed species could be taken only for scientific or research purposes. It is also stated in the paragraph that an amendment was made to allow take under other circumstances and provided incentives to non-federal land managers and private landowners to help protect listed and unlisted species. Thus, we can conclude that prior to the law being amended in 1982, displacement of a listed species was permitted when it served analysis or study objectives (i.e., for scientific or research purposes).
Therefore, the answer extracted from this context is: "only for scientific or research purposes"..
