Question

1. In this example, we have some modules that are defined in a way that specifies no inputs. This is not something you will commonly see because many times our modules perform some intermediary processing for our overall task along with the fact that we'd like to reuse our modules. For this problem, select the variable names that would be able to successfully linked to a value and have no conflicts. Be thinking about the scope of the variables.

Module main()
Display "doing some calculations!"
adder()
adder()
  subtractor()
Display "all done!"
End module

Module subtractor()
Number n1 = 5
Number n2 = 10
Number n1 = 7
Display n1 + n2
End Module

Module adder()
Number n1 = 60
Number n2 = 30
n2 = 7
Number n3 = n2 + 15
Display n3
End module

A. n1

B. n2

C. n3
