  Consider also noun phrases of the form the M that P and the M that not P. For instance: the gold that is in the safe and the gold that is not in the safe. Here, intuitions are very clear: the first noun phrase designates the solid bit of gold a, while the second designates b. However, under the mixed approach, The gold is not in the safe is true. This means that a+b (the gold) is in the denotation of is not in the safe. So it may seem that a+b is also in the denotation of gold that is not in the safe and in that of the gold that is not in the safe, contradicting speakers’ intuitions.
