Question: 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.
Try to answer this question if possible: Why do some countries display numbers in chunks of two to four numbers?
Answer: because we are able to chunk the information into meaningful groups of numbers
Question: Gaddafi briefly studied History at the University of Libya in Benghazi, before dropping out to join the military. Despite his police record, in 1963 he began training at the Royal Military Academy, Benghazi, alongside several like-minded friends from Misrata. The armed forces offered the only opportunity for upward social mobility for underprivileged Libyans, and Gaddafi recognised it as a potential instrument of political change. Under Idris, Libya's armed forces were trained by the British military; this angered Gaddafi, who viewed the British as imperialists, and accordingly he refused to learn English and was rude to the British officers, ultimately failing his exams. British trainers reported him for insubordination and abusive behaviour, stating their suspicion that he was involved in the assassination of the military academy's commander in 1963. Such reports were ignored and Gaddafi quickly progressed through the course.
Try to answer this question if possible: What crime was Gaddafi suspected of being involved in during his time in the military?
Answer: the assassination of the military academy's commander in 1963
Question: The 2010 maternal mortality rate per 100,000 births for Guinea Bissau was 1000. This compares with 804.3 in 2008 and 966 in 1990. The under 5 mortality rate, per 1,000 births, was 195 and the neonatal mortality as a percentage of under 5's mortality was 24. The number of midwives per 1,000 live births was 3; one out of eighteen pregnant women die as a result of pregnancy. According to a 2013 UNICEF report, 50% of women in Guinea Bissau had undergone female genital mutilation. In 2010, Guinea Bissau had the 7th highest maternal mortality rate in the world.
Try to answer this question if possible: How many midwives are listed per 1,000 live births?
Answer: 3
Question: In the British West Indian islands (and also in the United States), the majority of enslaved blacks brought across the Atlantic came from West Africa (roughly between modern Senegal and Ghana). Very little of Bermuda's original black emigration came from this area. The first blacks to arrive in Bermuda in any numbers were free blacks from Spanish-speaking areas of the West Indies, and most of the remainder were recently enslaved Africans captured from the Spanish and Portuguese. As Spain and Portugal sourced most of their slaves from South-West Africa (the Portuguese through ports in modern-day Angola; the Spanish purchased most of their African slaves from Portuguese traders, and from Arabs whose slave trading was centred in Zanzibar). Genetic studies have consequently shown that the African ancestry of black Bermudians (other than those resulting from recent immigration from the British West Indian islands) is largely from the a band across southern Africa, from Angola to Mozambique, which is similar to what is revealed in Latin America, but distinctly different from the blacks of the West Indies and the United States.
Try to answer this question if possible: What is one way we can show that black Bermudians are of different heritage than African Americans?
Answer:
Genetic studies
