Answer: Everything in the kitchen sink except the sink itself.
Explanation:
Out of the options given, the proposition is "Everything in the kitchen sink except the sink itself."
A proposition is a statement that can be either true or false. In this case, the statement is claiming that everything in the kitchen sink, excluding the sink itself, is true. This statement can be evaluated as either true or false, making it a proposition.
The other options, "Ouch! It ain't broke, so it don't gotta be fixed" and "You're weird," are not propositions because they do not make a claim that can be evaluated as true or false. They are more like expressions or exclamations rather than statements.
