A team of scientists has been studying a pack of wolves. Lately, the wolves have not been able to find food in their usual areas, so they disappear for long periods of time. The scientists think that this is because humans have moved closer to the edge of the forest, scaring the wolves. The scientists develop a special tool that lets them track where the wolves go to find food. What should they do to make sure their tool works the way it is supposed to?
a. They should bring the tool to a science fair and demonstrate for others how the tool is used.
b. They should find out if the people who moved near the forest want to try the tool out for themselves.
c. They should test the tool and see which features in the system work best and which need to be improved.
d. They should show the tool to other scientists and get their approval to use it in the forest with the wolves.
c. They should test the tool and see which features in the system work best and which need to be improved.
