Problem: Cubism:

The art historian Douglas Cooper states that Paul Gauguin and Paul Cézanne "were particularly influential to the formation of Cubism and especially important to the paintings of Picasso during 1906 and 1907". Cooper goes on to say: "The Demoiselles is generally referred to as the first Cubist picture. This is an exaggeration, for although it was a major first step towards Cubism it is not yet Cubist. The disruptive, expressionist element in it is even contrary to the spirit of Cubism, which looked at the world in a detached, realistic spirit. Nevertheless, the Demoiselles is the logical picture to take as the starting point for Cubism, because it marks the birth of a new pictorial idiom, because in it Picasso violently overturned established conventions and because all that followed grew out of it."

 What does Cooper say is the last Cubist picture?

A: unanswerable


Problem: By 1820, Charleston's population had grown to 23,000, maintaining its black (and mostly slave) majority. When a massive slave revolt planned by Denmark Vesey, a free black, was revealed in May 1822, whites reacted with intense fear, as they were well aware of the violent retribution of slaves against whites during the Haitian Revolution. Soon after, Vesey was tried and executed, hanged in early July with five slaves. Another 28 slaves were later hanged. Later, the state legislature passed laws requiring individual legislative approval for manumission (the freeing of a slave) and regulating activities of free blacks and slaves.
How was Vesey executed in 1822?

Answer: hanged


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Cultural practices in the Americas seem to have been shared mostly within geographical zones where unrelated peoples adopted similar technologies and social organizations. An example of such a cultural area is Mesoamerica, where millennia of coexistence and shared development among the peoples of the region produced a fairly homogeneous culture with complex agricultural and social patterns. Another well-known example is the North American plains where until the 19th century several peoples shared the traits of nomadic hunter-gatherers based primarily on buffalo hunting.
What creature did the nomadic hunter-gatherers of the plains hunt?
A: buffalo


Context and question: In its metaphysics, Nyāya school is closer to the Vaiśeṣika school than others. It holds that human suffering results from mistakes/defects produced by activity under wrong knowledge (notions and ignorance). Moksha (liberation), it states, is gained through right knowledge. This premise led Nyāya to concern itself with epistemology, that is the reliable means to gain correct knowledge and to remove wrong notions. False knowledge is not merely ignorance to Naiyayikas, it includes delusion. Correct knowledge is discovering and overcoming one's delusions, and understanding true nature of soul, self and reality. The Nyāya Sūtras begin:
What school of thought is closest to Vaisesika school?
Answer: Nyāya

Problem: Annelid:

The earliest good evidence for oligochaetes occurs in the Tertiary period, which began 65 million years ago, and it has been suggested that these animals evolved around the same time as flowering plants in the early Cretaceous, from 130 to 90 million years ago. A trace fossil consisting of a convoluted burrow partly filled with small fecal pellets may be evidence that earthworms were present in the early Triassic period from 251 to 245 million years ago. Body fossils going back to the mid Ordovician, from 472 to 461 million years ago, have been tentatively classified as oligochaetes, but these identifications are uncertain and some have been disputed.

When did the Tertiary period begin?
---
A:
65 million years ago
