 The commissioner was most impressed by the result of your answers.
 He has now asked your help to create a training program for the future police inspectors. You gladly accept as you think that this will help lessen your burden of fighting crime in the future.
 
-In a training folder, various folders `mistery` were prepared with some key differences in the data for each group of trainees.

+To simplify your life as a teacher and as the answers will not be exactly the same in each `mystery` folder, you need to write a `teacher.sh` file that does the following:
 
-- step 1, it enters the `mistery` folder.
-- step 2, it isolates into an environment variable the number (**and only the number**) of the appropriate interview that helped solved the mistery (Unlike the interview number, the adress will not change across the `mistery` folders that will be tested).
-- step 3, it prints the newly created environment variable.(Once again **the number and only the number**)
+- step 1, it enters the `mystery` folder.
+- step 2, it isolates, thru as similar command that you used to find it, and into an environment variable, the number (**and only the number**) of the key interview that helped solved the mystery (Unlike the interview number, the adress will not change across the `mystery` folders that will be tested, hence the command to find the interview is the same across all the `mystery` folder that will be tested).
+- step 3, it prints the newly created environment variable.
 - step 4, it prints what the interview contains.
-- step 5, it executes the command that should have printed the shorted list of 4 suspects.
-- step 6, it executes the command that should have gotten your main suspect convicted (as reminder the result of that command should be the printing of a number) except that now you replace your suspect name with the environment variable MAIN_SUSPECT.
+- step 5, it executes the command that should have printed the shorted list of 4 suspects. (it shows only the license Plate, the Make, the Color, the Owner, and the Height)
+- step 6, it executes the command that should have gotten your main suspect convicted (as a reminder the result of that command should be the printing of a number) except that now you replace your suspect name with the environment variable MAIN_SUSPECT.
 
-- step 7, step 1 to 6 are repeated for each `mistery`.
+- step 7, step 1 to 6 are repeated for each `mystery` folder of the training folder that the program works in.
 
-Note that for **step 2 to 6**, all the commands have to be executed with keeping in mind that the `mistery` folder is the current directory but that its name will vary.
