Feral cats kill large numbers of native wildlife in Australia. Which technology would allow environmental scientists to know the
exact locations of individual feral cats at all times? A. Global positioning systems (GPS)
B. Environmental DNA (eDNA) surveillance
C. Acoustics
D. Gel electrophoresis
The correct answer is A. In order to keep track of the feral cats' location, the animals should have a GPS tag that can be monitored. After the animal has been tagged and released, the scientists can track the movement of the animal and know its exact location at all times.
