A parliament and constitution were proclaimed. The first president was Ruggero Settimo. The Bourbons reconquered Palermo in 1849, and remained under their rule until the time of Giuseppe Garibaldi. The famous general entered Palermo with his troops (the “Thousands”) on 27 May 1860. After the plebiscite later that year Palermo, along with the rest of Sicily, became part of the new Kingdom of Italy (1861).
Who regained control of Palermo in 1849?

Problem: Please answer a question about the following article about Diarrhea:
About 1.7 to 5 billion cases of diarrhea occur per year. It is most common in developing countries, where young children get diarrhea on average three times a year. Total deaths from diarrhea are estimated at 1.26 million in 2013 – down from 2.58 million in 1990. In 2012, it is the second most common cause of deaths in children younger than five (0.76 million or 11%). Frequent episodes of diarrhea are also a common cause of malnutrition and the most common cause in those younger than five years of age. Other long term problems that can result include stunted growth and poor intellectual development.
Frequent episodes of diarrhea are common in what type of cases?
A: malnutrition


Question: Read this and answer the question

DNA samples from 1228 Russians show that the Y chromosomes analyzed, all except 20 (1.6%) fall into seven major haplogroups all characteristic to West Eurasian populations. Taken together, they account for 95% of the total Russian Y chromosomal pool. Only (0.7%) fell into haplogroups that are specific to East and South Asian populations. Mitochondrial DNA (mtDNA) examined in Poles and Russians revealed the presence of all major European haplogroups, which were characterized by similar patterns of distribution in Poles and Russians. An analysis of the DNA did not reveal any specific combinations of unique mtDNA haplotypes and their subclusters. The DNA clearly shows that both Poles and Russians are not different from the neighbouring European populations.

Taken together, they account for what percentage of the total Russian Y chromosomal pool?
Answer: 95%


Problem: Romantic relationships tend to increase in prevalence throughout adolescence. By age 15, 53% of adolescents have had a romantic relationship that lasted at least one month over the course of the previous 18 months. In a 2008 study conducted by YouGov for Channel 4, 20% of 14−17-year-olds surveyed revealed that they had their first sexual experience at 13 or under in the United Kingdom. A 2002 American study found that those aged 15–44 reported that the average age of first sexual intercourse was 17.0 for males and 17.3 for females. The typical duration of relationships increases throughout the teenage years as well. This constant increase in the likelihood of a long-term relationship can be explained by sexual maturation and the development of cognitive skills necessary to maintain a romantic bond (e.g. caregiving, appropriate attachment), although these skills are not strongly developed until late adolescence. Long-term relationships allow adolescents to gain the skills necessary for high-quality relationships later in life and develop feelings of self-worth. Overall, positive romantic relationships among adolescents can result in long-term benefits. High-quality romantic relationships are associated with higher commitment in early adulthood and are positively associated with self-esteem, self-confidence, and social competence. For example, an adolescent with positive self-confidence is likely to consider themselves a more successful partner, whereas negative experiences may lead to low confidence as a romantic partner. Adolescents often date within their demographic in regards to race, ethnicity, popularity, and physical attractiveness. However, there are traits in which certain individuals, particularly adolescent girls, seek diversity. While most adolescents date people approximately their own age, boys typically date partners the same age or younger; girls typically date partners the same age or older.
At what average age did American females report their first sexual intercourse took place?
The answer is the following: 17.3


In the late renaissance various writers began to question the medieval and classical understanding of knowledge acquisition in a more fundamental way. In political and historical writing Niccolò Machiavelli and his friend Francesco Guicciardini initiated a new realistic style of writing. Machiavelli in particular was scornful of writers on politics who judged everything in comparison to mental ideals and demanded that people should study the "effectual truth" instead. Their contemporary, Leonardo da Vinci (1452–1519) said, "If you find from your own experience that something is a fact and it contradicts what some authority has written down, then you must abandon the authority and base your reasoning on your own findings."
When did da Vinci die?
1519


Here is a question about this article: Neptune's weather is characterised by extremely dynamic storm systems, with winds reaching speeds of almost 600 m/s (2,200 km/h; 1,300 mph)—nearly reaching supersonic flow. More typically, by tracking the motion of persistent clouds, wind speeds have been shown to vary from 20 m/s in the easterly direction to 325 m/s westward. At the cloud tops, the prevailing winds range in speed from 400 m/s along the equator to 250 m/s at the poles. Most of the winds on Neptune move in a direction opposite the planet's rotation. The general pattern of winds showed prograde rotation at high latitudes vs. retrograde rotation at lower latitudes. The difference in flow direction is thought to be a "skin effect" and not due to any deeper atmospheric processes. At 70° S latitude, a high-speed jet travels at a speed of 300 m/s.
What is the answer to this question: What is the effect called that describes the flow direction on Neptune? 
****
So...
skin effect
