Problem: Cubism:

Historians have divided the history of Cubism into phases. In one scheme, the first phase of Cubism, known as Analytic Cubism, a phrase coined by Juan Gris a posteriori, was both radical and influential as a short but highly significant art movement between 1910 and 1912 in France. A second phase, Synthetic Cubism, remained vital until around 1919, when the Surrealist movement gained popularity. English art historian Douglas Cooper proposed another scheme, describing three phases of Cubism in his book, The Cubist Epoch. According to Cooper there was "Early Cubism", (from 1906 to 1908) when the movement was initially developed in the studios of Picasso and Braque; the second phase being called "High Cubism", (from 1909 to 1914) during which time Juan Gris emerged as an important exponent (after 1911); and finally Cooper referred to "Late Cubism" (from 1914 to 1921) as the last phase of Cubism as a radical avant-garde movement. Douglas Cooper's restrictive use of these terms to distinguish the work of Braque, Picasso, Gris (from 1911) and Leger (to a lesser extent) implied an intentional value judgement.

From what years did High Cubism take place?
---
A: 1909 to 1914

Problem: Westminster Abbey:

Henry VII added a Perpendicular style chapel dedicated to the Blessed Virgin Mary in 1503 (known as the Henry VII Chapel or the "Lady Chapel"). Much of the stone came from Caen, in France (Caen stone), the Isle of Portland (Portland stone) and the Loire Valley region of France (tuffeau limestone).[citation needed]

Who took away a Perpendicular style chapel?
---
A: unanswerable

Problem: Virgil:

The Georgics' tone wavers between optimism and pessimism, sparking critical debate on the poet's intentions, but the work lays the foundations for later didactic poetry. Virgil and Maecenas are said to have taken turns reading the Georgics to Octavian upon his return from defeating Antony and Cleopatra at the Battle of Actium in 31 BC.

Octavian defeated Antony and Cleopatra at which battle?
---
A: Battle of Actium

Problem: Alfred North Whitehead:

In addition to numerous articles on mathematics, Whitehead wrote three major books on the subject: A Treatise on Universal Algebra (1898), Principia Mathematica (co-written with Bertrand Russell and published in three volumes between 1910 and 1913), and An Introduction to Mathematics (1911). The former two books were aimed exclusively at professional mathematicians, while the latter book was intended for a larger audience, covering the history of mathematics and its philosophical foundations. Principia Mathematica in particular is regarded as one of the most important works in mathematical logic of the 20th century.

With what mathematician and philosopher did Whitehead collaborate to write Principia Mathematica?
---
A:
Bertrand Russell
