The problem: Answer a question about this article:
Henry II wanted to secure the southern borders of Aquitaine and decided to betroth his youngest son to Alais, the daughter and heiress of Humbert III of Savoy. As part of this agreement John was promised the future inheritance of Savoy, Piedmont, Maurienne, and the other possessions of Count Humbert. For his part in the potential marriage alliance, Henry II transferred the castles of Chinon, Loudun and Mirebeau into John's name; as John was only five years old his father would continue to control them for practical purposes. Henry the Young King was unimpressed by this; although he had yet to be granted control of any castles in his new kingdom, these were effectively his future property and had been given away without consultation. Alais made the trip over the Alps and joined Henry II's court, but she died before marrying John, which left the prince once again without an inheritance.
Who was Alais?
****
The answer: the daughter and heiress of Humbert III of Savoy

In 1348, the Black Death and other disasters sealed a sudden end to the previous period of massive philosophic and scientific development. Yet, the rediscovery of ancient texts was improved after the Fall of Constantinople in 1453, when many Byzantine scholars had to seek refuge in the West. Meanwhile, the introduction of printing was to have great effect on European society. The facilitated dissemination of the printed word democratized learning and allowed a faster propagation of new ideas. New ideas also helped to influence the development of European science at this point: not least the introduction of Algebra. These developments paved the way for the Scientific Revolution, which may also be understood as a resumption of the process of scientific inquiry, halted at the start of the Black Death.
Printed word enabled what?
****
The answer: a faster propagation of new ideas

The problem: Answer a question about this article:
Short-term memory is also known as working memory. Short-term memory allows recall for a period of several seconds to a minute without rehearsal. Its capacity is also very limited: George A. Miller (1956), when working at Bell Laboratories, conducted experiments showing that the store of short-term memory was 72 items (the title of his famous paper, "The magical number 72"). Modern estimates of the capacity of short-term memory are lower, typically of the order of 45 items; however, memory capacity can be increased through a process called chunking. For example, in recalling a ten-digit telephone number, a person could chunk the digits into three groups: first, the area code (such as 123), then a three-digit chunk (456) and lastly a four-digit chunk (7890). This method of remembering telephone numbers is far more effective than attempting to remember a string of 10 digits; this is because we are able to chunk the information into meaningful groups of numbers. This may be reflected in some countries in the tendency to display telephone numbers as several chunks of two to four numbers.
Why do some countries display numbers in chunks of two to four numbers?
****
The answer:
because we are able to chunk the information into meaningful groups of numbers
