premise: The Toffee Crisp bar is a chocolate bar first manufactured in the United Kingdom by Mackintosh's in 1963. It is now produced by Nestlé in the UK. It consists of puffed rice embedded in soft toffee and shaped into a rectangular cuboid, the whole bar being covered by milk chocolate.
hypothesis: The Toffee Crisp bar is not sold in the US.
reason: The candy bar is sold in the UK but it doesn't say if it's sold in the US. The system knows it's sold in the UK.
