In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.

Ex Input:
Laplaces rule may be used to compute a version of this quantity for its namesake tensor in order to prove the Alon-Tarsi conjecture for Latin squares of even order; that proof uses Cayleys version of this operator. The Cauchy-Binet rule generalizes it to commutative rings, while Leibnizs formula uses permutations of elements to compute it. Setting to zero the result of this operation on lambda I minus A allows us to calculate As eigenvalues. Cramers rule uses ratios of these to solve systems of linear equations. For ten points, name this quantity that is a d minus c b for a 2 by 2 matrix a b c d.

Ex Input:
Lindstrom's theorem states that first-order logic is the strongest logic having both this property and satisfying the Lowenheim-Skolem property. A method for finding a Hausdorff space with this property containing a given space is named for Stone and Cech. Equicontinuity is the main condition for determining whether a family of functions has this property by the Arzela-Ascoli theorem. Using the axiom of choice, it can be shown that an arbitrary product of spaces with this property has this property, a result known as Tychonoff's theorem. In Euclidean space, being closed and bounded is sufficient to show, according to the Heine-Borel theorem, that a set has this property. For 10 points, identify this property which holds of a set on which every open cover has a finite subcover.

Ex Input:
Act II features one of the characters remembering his time in Morocco where he had to fend off a child prostitute, while Act IV begins with Dr. Baugh arriving to deliver some morphine and a woman coming to realize that her husband has terminal cancer. One of the central characters repeatedly asks for "solid quiet" and drinks until he hears a "click" in his head so that he can forget the death of his best friend, and possible lover, Skipper. Ultimately, the greedy and oddly fertile Mae and Gooper lose out as Big Daddy names the other Pollitt son as his heir. FTP, name this 1955 play that revolves around the doomed marriage of Brick and his wife Maggie, a work by Tennessee Williams.
