premise: The news comes as the owners of Kilroot announced plans to install clean-up equipment at the plant near Carrickfergus at a cost of Â£35 million.
hypothesis: The owners brush their hair
reason: The owners might brush their hair, but they might not brush their hair making this statement neither correct nor incorrect. Plus it's unrelated to the topic sentence. I am not sure why this statement fooled the model, and not the other things I submitted. Maybe something about the words I used knocked it off.
