 Q1. Why is the report method untestable ? [2 pts]
 
-
+Ans - 
+     1. As the  file path is user/OS/System specific
+	 2. inputs  to report method  depends on colabrataive (Range)
+	 3. While writing  msg to a report file its constructed  from numbers.
+	 4. it is easy to use for writer but not to user who is  using it.
 
 
 Q2. How will you change the api of the report method to make it more testable ? [2 pts]
 
+Ans :-
+     1. For handelling the file pale we wili use file handler
