Text: I saw in the catalog how the lengthy diamond necklaces with complex pendants were often made to be disassembled by the client, so she could have four bracelets, two brooches, and a shorter necklace whenever she got tired of the one big thing.
Entailment: I saw that some necklaces could be broken down into separate pieces of jewelry.
Contradiction: There was a diamond necklace in the whole world that could be disassembled.
