Three test environments select​

Three test environments were selected for our experiments: a law office, a laboratory in which experiments were performed using laboratory rats, and an automobile assembly line.

One-way mirrored glass panels were installed to allow video cameras to record the activity and researchers to observe the same and take notes.

We secretly inserted observers directly into the work environment. These observers posed as outside contractors and were in uniform as maintenance and cleaning staff, coffee and water service vendors, and similar supporting personnel.

The observers were drawn from the students who had been matriculated  into the experimental psychology courses from which this study was developed as an example of such studies generally.

Full thing is:

the figurative meanings of these lines are questioning the tyger's strength and beauty. the meaning contributes to the overall message of them poem because it is explaining how strong the tyger is.

now just elaborate off of that. : )

racial profiling is the act of targeting a racial minority for a criminal investigation only based on the individual's skin color, and therefore the association of that person to a race or ethnic group.

criminal profiling on the other hand, is the practice hold by police enforcement members, in which they stop for questioning an individual based on his/her appearance and the similarity between them and a suspect the police is looking for. in this case, race can be used for criminal profiling, but eyes color, hair color, height, weight, type of clothes wearing, etc, are also taking in consideration.
