[2] In this form, set-builder notation has three parts: a variable, a colon or vertical bar separator, and a predicate. Thus there is a variable on the left of the ...

Set-builder notation makes use of predicates to define sets. In autoepistemic logic , which rejects the law of excluded middle, predicates may be true, false, or simply unknown . In particular, a given collection of facts may be insufficient to determine the truth or falsehood of a predicate.
However, in 2020, due to the COVID-19 pandemic, the AP exams were administered remotely as drastically shortened open-note exams, and the exam consisted of a single modified DBQ essay.
