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.

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.
Science

This force is represented by a first derivative with respect to position in the harmonic oscillator equation. In one model, this force stems from tiny electrostatic repulsions. It can be understood as the parallel shear component of the contact force, whose other component is typically calculated as mg cosine theta. It is calculated from a coefficient, symbolized mu, multiplied by the normal force. Rolling motion is affected by the "kinetic" type of this force, which is known as "drag" in fluids. For 10 points, name this force that resists the motion of objects against one another.

Howard Barker discussed the aftermath of this battle in Scenes from an Execution, and the Fontana dei Quattro Mori in Marino commemorates it. It reversed the outcome of the Battle of Preveza fought forty-four years earlier, and it was followed by a brief campaign of expansion which captured Tunis. The Marqus de Santa Cruz's reserve forces helped annihilate the defeated side after this event, whose immediate cause was the siege of Famagusta and capture of Nicosia during a war over Cyprus, whose surrender two years later reversed this battle's practical impact. The king of one country involved in this event appointed Luis de Requesens responsible for controlling the temper of the military commander, whose other lieutenants included Alessandro Farnese and Andrea Doria. FTP, name this battle in which Pius V's Holy League fleet commanded by Don John of Austria sailed to the Gulf of Corinth and defeated Ali Pasha in 1571.
