About arguments
Enter the path to the csv file in the argument
    
About the return value
The first return value is the answer for each question and a hash that does not allow duplicate integers.
The second return value is the data frame in which the answer is replaced with a numerical value.
    
-Normalize column names with notational fluctuations
-Delete the time stamp column
