Problem: On the Origin of Species:

French-speaking naturalists in several countries showed appreciation of the much modified French translation by Clemence Royer, but Darwin's ideas had little impact in France, where any scientists supporting evolutionary ideas opted for a form of Lamarckism. The intelligentsia in Russia had accepted the general phenomenon of evolution for several years before Darwin had published his theory, and scientists were quick to take it into account, although the Malthusian aspects were felt to be relatively unimportant. The political economy of struggle was criticised as a British stereotype by Karl Marx and by Leo Tolstoy, who had the character Levin in his novel Anna Karenina voice sharp criticism of the morality of Darwin's views.

Which author voiced his displeasure of the morality of Darwin's views in a novel?
---
A: Leo Tolstoy

Problem: The first step toward Indian self-rule was the appointment of councillors to advise the British viceroy in 1861 and the first Indian was appointed in 1909. Provincial Councils with Indian members were also set up. The councillors' participation was subsequently widened into legislative councils. The British built a large British Indian Army, with the senior officers all British and many of the troops from small minority groups such as Gurkhas from Nepal and Sikhs. The civil service was increasingly filled with natives at the lower levels, with the British holding the more senior positions.
What appointments were the first step in Indian self-rule?
---
Answer: councillors

Synapses are the key functional elements of the brain. The essential function of the brain is cell-to-cell communication, and synapses are the points at which communication occurs. The human brain has been estimated to contain approximately 100 trillion synapses; even the brain of a fruit fly contains several million. The functions of these synapses are very diverse: some are excitatory (exciting the target cell); others are inhibitory; others work by activating second messenger systems that change the internal chemistry of their target cells in complex ways. A large number of synapses are dynamically modifiable; that is, they are capable of changing strength in a way that is controlled by the patterns of signals that pass through them. It is widely believed that activity-dependent modification of synapses is the brain's primary mechanism for learning and memory.
How many synapses does the human brain supposedly contain?
A: 100 trillion synapses;

Context and question: While it is undisputed that early humans were hunters, the importance of this for the emergence of the Homo genus from the earlier Australopithecines, including the production of stone tools and eventually the control of fire, are emphasised in the hunting hypothesis and de-emphasised in scenarios that stress omnivory and social interaction, including mating behaviour, as essential in the emergence of human behavioural modernity. With the establishment of language, culture, and religion, hunting became a theme of stories and myths, as well as rituals such as dance and animal sacrifice.
What is undisputed about early humans?
Answer: were hunters

Question: In January 1977, Droney promoted him to First Assistant District Attorney, essentially making Kerry his campaign and media surrogate because Droney was afflicted with amyotrophic lateral sclerosis (ALS, or Lou Gehrig's Disease). As First Assistant, Kerry tried cases, which included winning convictions in a high-profile rape case and a murder. He also played a role in administering the office, including initiating the creation of special white-collar and organized crime units, creating programs to address the problems of rape and other crime victims and witnesses, and managing trial calendars to reflect case priorities. It was in this role in 1978 that Kerry announced an investigation into possible criminal charges against then Senator Edward Brooke, regarding "misstatements" in his first divorce trial. The inquiry ended with no charges being brought after investigators and prosecutors determined that Brooke's misstatements were pertinent to the case, but were not material enough to have affected the outcome.
Is there an answer to this question: What senator did Kerry investigate in 1978?

Answer: Edward Brooke

There are more than 200 thermochemical cycles which can be used for water splitting, around a dozen of these cycles such as the iron oxide cycle, cerium(IV) oxidecerium(III) oxide cycle, zinc zinc-oxide cycle, sulfur-iodine cycle, copper-chlorine cycle and hybrid sulfur cycle are under research and in testing phase to produce hydrogen and oxygen from water and heat without using electricity. A number of laboratories (including in France, Germany, Greece, Japan, and the USA) are developing thermochemical methods to produce hydrogen from solar energy and water.
What countries are testing this?
A:
France, Germany, Greece, Japan, and the USA
