Premise: The night was very calm and still .<br>Not a breath of wind stirred .<br>The moonshine was the brightest I had ever seen .<br>In the middle of the garden , where the shadow of the poplars did not fall , it was almost as bright as day .<br>One could have read fine print .
Hypothesis: The moonshine was the brightest I had ever seen, because it was the first time I had ever seen moonshine.
