John purchased a toy for his young daughter. The toy included nine colorful plastic pieces in the shape of the numbers from 1 to 9. In examining these pieces he made the following observations: One piece is purple and two pieces each are red, green, yellow, and blue.
The two red pieces are consecutive numbers.
The number 4 is green.
The two blue pieces are not consecutive numbers
Both the 1 and the 9 are yellow
The purple piece is not a number immediately greater than or less than either green piece

Clarification:

I found the complete instructions for the exercise online:

If one of the red pieces is the number 3, what number is the other red piece?

A.2

B.4

C.5

D.6

E.7

A. 2

Explanation:

In this exercise, you have to answer the question after analyzing the information given about the pieces. The correct answer is "2" because both red plastic pieces are consecutive, and one of the red pieces is the number 3. The correct answer couldn't be number 4 because number 4 is one of the green pieces.

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.
