Problem: Hunting:

Archaeologist Louis Binford criticised the idea that early hominids and early humans were hunters. On the basis of the analysis of the skeletal remains of the consumed animals, he concluded that hominids and early humans were mostly scavengers, not hunters, and this idea is popular among some archaeologists and paleoanthropologists. Robert Blumenschine proposed the idea of confrontational scavenging, which involves challenging and scaring off other predators after they have made a kill, which he suggests could have been the leading method of obtaining protein-rich meat by early humans.

What idea was criticized by Robert Blumenschine?

A: unanswerable

Problem: Frederic Chopin:

Fryderyk may have had some piano instruction from his mother, but his first professional music tutor, from 1816 to 1821, was the Czech pianist Wojciech Zywny. His elder sister Ludwika also took lessons from Zywny, and occasionally played duets with her brother. It quickly became apparent that he was a child prodigy. By the age of seven Fryderyk had begun giving public concerts, and in 1817 he composed two polonaises, in G minor and B-flat major. His next work, a polonaise in A-flat major of 1821, dedicated to Zywny, is his earliest surviving musical manuscript.

What did Frederic compose during the year of 1817?
---
A: two polonaises

Problem: Muslim world:

A Latin translation of Ibn Tufail's work, Philosophus Autodidactus, first appeared in 1671, prepared by Edward Pococke the Younger, followed by an English translation by Simon Ockley in 1708, as well as German and Dutch translations. These translations might have later inspired Daniel Defoe to write Robinson Crusoe, regarded as the first novel in English. Philosophus Autodidactus, continuing the thoughts of philosophers such as Aristotle from earlier ages, inspired Robert Boyle to write his own philosophical novel set on an island, The Aspiring Naturalist.

What did Edward Pococke the Younger translate in the 16th century?
---
A: unanswerable
