[Haskell-beginners] Is this scope range problem?

[Sok H. Chang]

Thank you so much, Luca.
Mmm... I want to make a "List of Sentence" from some text file.

inputFile.txt is like this.
--------------------------------
This is a pen.
Is this a pen?
etc...many sentence. Each line, only one sentence.

How can I make a list of sentence?
How can I declared inpStr?

Thank you.

Sincerely, Sok Chang
