According to your reading, the save our springs alliance is an example of what type of interest group?
a. local
b. state
c. national
d. international

The answer is a. local.  It is clear from what I’ve read that it is a group in local community who wishes to preserve their springs which they value very much.  Usually organization that fall in the other three categories would use more sophisticated ways to get support for their cause.  In some cases, they have some backing from affluent people.

i believe the answer is:   psychological  experiment

in this experiment, wilhelm wundt became the first person that implement scientific method in analyzing the pyschological phenomenon.

due to this result, wilhelm wundt also able to make psychology to be acknowledged as a separate scientific field from biology.
