Take the following as truth: All the ground floor windows were shuttered tight, but upstairs, on the first floor (it was a two-storied house) I noticed a window with a light burning and the curtains not drawn.
Then the following statement: "A solitary window on the first floor of the two story house glowed with a light burning and undrawn curtains, even though the ground floor windows were all shuttered tight." is true, false, or inconclusive?
Answer: True
