The Castro culture ('Culture of the Castles') developed during the Iron Age, and flourished during the second half of the first millennium BC. It is usually considered a local evolution of the Atlantic Bronze Age, with later developments and influences and overlapping into the Roman era. Geographically, it corresponds to the people Roman called Gallaeci, which were composed by a large series of nations or tribes, among them the Artabri, Bracari, Limici, Celtici, Albiones and Lemavi. They were capable fighters: Strabo described them as the most difficult foes the Romans encountered in conquering Lusitania, while Appian mentions their warlike spirit, noting that the women bore their weapons side by side with their men, frequently preferring death to captivity. According to Pomponius Mela all the inhabitants of the coastal areas were Celtic people.
Who was it that described people living on the coast as "Celtic"?
Pomponius Mela


Input: Vacuum
To continue evacuating a chamber indefinitely without requiring infinite growth, a compartment of the vacuum can be repeatedly closed off, exhausted, and expanded again. This is the principle behind positive displacement pumps, like the manual water pump for example. Inside the pump, a mechanism expands a small sealed cavity to create a vacuum. Because of the pressure differential, some fluid from the chamber (or the well, in our example) is pushed into the pump's small cavity. The pump's cavity is then sealed from the chamber, opened to the atmosphere, and squeezed back to a minute size.

How is a vacuum created inside of a manual water pump?
Output: a mechanism expands a small sealed cavity


Input: Article: In 1918 Whitehead's academic responsibilities began to seriously expand as he accepted a number of high administrative positions within the University of London system, of which Imperial College London was a member at the time. He was elected Dean of the Faculty of Science at the University of London in late 1918 (a post he held for four years), a member of the University of London's Senate in 1919, and chairman of the Senate's Academic (leadership) Council in 1920, a post which he held until he departed for America in 1924. Whitehead was able to exert his newfound influence to successfully lobby for a new history of science department, help establish a Bachelor of Science degree (previously only Bachelor of Arts degrees had been offered), and make the school more accessible to less wealthy students.

Now answer this question: In which year did Whitehead relocate to America?

Output: 1924


Article: Popper contrasts his views with the notion of the "hopeful monster" that has large phenotype mutations and calls it the "hopeful behavioural monster". After behaviour has changed radically, small but quick changes of the phenotype follow to make the organism fitter to its changed goals. This way it looks as if the phenotype were changing guided by some invisible hand, while it is merely natural selection working in combination with the new behaviour. For example, according to this hypothesis, the eating habits of the giraffe must have changed before its elongated neck evolved. Popper contrasted this view as "evolution from within" or "active Darwinism" (the organism actively trying to discover new ways of life and being on a quest for conquering new ecological niches), with the naturalistic "evolution from without" (which has the picture of a hostile environment only trying to kill the mostly passive organism, or perhaps segregate some of its groups).

Question: Which aspect of organisms changes most radically in the process of evolution Popper envisions?
Ans: behaviour


Here is a question about this article: At low frequencies (such as AM broadcast), arrays of vertical towers are used to achieve directionality  and they will occupy large areas of land. For reception, a long Beverage antenna can have significant directivity. For non directional portable use, a short vertical antenna or small loop antenna works well, with the main design challenge being that of impedance matching. With a vertical antenna a loading coil at the base of the antenna may be employed to cancel the reactive component of impedance; small loop antennas are tuned with parallel capacitors for this purpose.
What is the answer to this question: Why is this specific antenna type used?
****
So... achieve directionality


Article: Hospitals in Liberia include the John F. Kennedy Medical Center in Monrovia and several others. Life expectancy in Liberia is estimated to be 57.4 years in 2012. With a fertility rate of 5.9 births per woman, the maternal mortality rate stood at 990 per 100,000 births in 2010. A number of highly communicable diseases are widespread, including tuberculosis, diarrheal diseases and malaria. In 2007, the HIV infection rates stood at 2% of the population aged 15–49  whereas the incidence of tuberculosis was 420 per 100,000 people in 2008. Approximately 58.2% – 66% of women are estimated to have undergone female genital mutilation.

Question: What were the HIV infection rates in 2007?
Ans:
2%
