Answer: True.
Explanation: The question is "En el Gran Chaco se puede ver animales en peligro de extinción."
and, in English, is:
"in the Gran Chaco, you can see animals in danger of extinction"
The Gran Chaco was and is greatly affected by deforestation, and this, combined with illegal hunters, put in danger the lives of the local wildlife, for example, there are animals like the "yaguarete" or the "tatu carrera" that are in a critical point.
So the sentence would be true, there are animals in danger of extintion in the Gran Chaco.
