Input: Read this: Today, all humans are classified as belonging to the species Homo sapiens and sub-species Homo sapiens sapiens. However, this is not the first species of homininae: the first species of genus Homo, Homo habilis, are theorized to have evolved in East Africa at least 2 million years ago, and members of this species populated different parts of Africa in a relatively short time. Homo erectus is theorized to have evolved more than 1.8 million years ago, and by 1.5 million years ago had spread throughout Europe and Asia. Virtually all physical anthropologists agree that Archaic Homo sapiens (A group including the possible species H. heidelbergensis, H. rhodesiensis and H. neanderthalensis) evolved out of African Homo erectus ((sensu lato) or Homo ergaster).
Question: What species do all living humans today belong to?

Output: Homo sapiens


QUES: The earliest signs were often not painted but consisted, for example, of paraphernalia connected with the brewing process such as bunches of hops or brewing implements, which were suspended above the door of the pub. In some cases local nicknames, farming terms and puns were used. Local events were often commemorated in pub signs. Simple natural or religious symbols such as 'The Sun', 'The Star' and 'The Cross' were incorporated into pub signs, sometimes being adapted to incorporate elements of the heraldry (e.g. the coat of arms) of the local lords who owned the lands upon which the pub stood. Some pubs have Latin inscriptions.

Local pub nicknames were often related to what profession?
What is the answer?
ANS: farming


QUES: About 75% of the population is employed in subsistence agriculture upon Swazi Nation Land (SNL). In contrast with the commercial farms, Swazi Nation Land suffers from low productivity and investment. This dual nature of the Swazi economy, with high productivity in textile manufacturing and in the industrialised agricultural TDLs on the one hand, and declining productivity subsistence agriculture (on SNL) on the other, may well explain the country's overall low growth, high inequality and unemployment.
Where is commercial farming productivity declining?

ANS: unanswerable


During the Middle Ages Aristotle's theory of tabula rasa was developed by Islamic philosophers starting with Al Farabi, developing into an elaborate theory by Avicenna and demonstrated as a thought experiment by Ibn Tufail. For Avicenna (Ibn Sina), for example, the tabula rasa is a pure potentiality that is actualized through education, and knowledge is attained through "empirical familiarity with objects in this world from which one abstracts universal concepts" developed through a "syllogistic method of reasoning in which observations lead to propositional statements which when compounded lead to further abstract concepts". The intellect itself develops from a material intellect (al-'aql al-hayulani), which is a potentiality "that can acquire knowledge to the active intellect (al-'aql al-fa'il), the state of the human intellect in conjunction with the perfect source of knowledge". So the immaterial "active intellect", separate from any individual person, is still essential for understanding to occur.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who developed the syllogistic method?
Ah, so.. unanswerable


Question: Victoria wrote to her uncle Leopold, whom Victoria considered her "best and kindest adviser", to thank him "for the prospect of great happiness you have contributed to give me, in the person of dear Albert ... He possesses every quality that could be desired to render me perfectly happy. He is so sensible, so kind, and so good, and so amiable too. He has besides the most pleasing and delightful exterior and appearance you can possibly see." However at 17, Victoria, though interested in Albert, was not yet ready to marry. The parties did not undertake a formal engagement, but assumed that the match would take place in due time.
Try to answer this question if possible: How old was Victoria when she met Albert?
Answer: 17


Input: Read this: Multi-layer printed circuit boards have trace layers inside the board. This is achieved by laminating a stack of materials in a press by applying pressure and heat for a period of time. This results in an inseparable one piece product. For example, a four-layer PCB can be fabricated by starting from a two-sided copper-clad laminate, etch the circuitry on both sides, then laminate to the top and bottom pre-preg and copper foil. It is then drilled, plated, and etched again to get traces on top and bottom layers.
Question: If you started with a two-sided laminate etched on either side, laminated to the top and bottom, and processed it again to get traces on the outside layers, how many layers would your final PCB have?

Output:
four
