Examples of common human diseases caused by viruses include the common cold, influenza, chickenpox, and cold sores. Many serious diseases such as rabies, Ebola virus disease, AIDS (HIV), avian influenza, and SARS are caused by viruses. The relative ability of viruses to cause disease is described in terms of virulence. Other diseases are under investigation to discover if they have a virus as the causative agent, such as the possible connection between human herpesvirus 6 (HHV6) and neurological diseases such as multiple sclerosis and chronic fatigue syndrome. There is controversy over whether the bornavirus, previously thought to cause neurological diseases in horses, could be responsible for psychiatric illnesses in humans.Viruses have different mechanisms by which they produce disease in an organism, which depends largely on the viral species. Mechanisms at the cellular level primarily include cell lysis, the breaking open and subsequent death of the cell. In multicellular organisms, if enough cells die, the whole organism will start to suffer the effects. Although viruses cause disruption of healthy homeostasis, resulting in disease, they may exist relatively harmlessly within an organism. An example would include the ability of the herpes simplex virus, which causes cold sores, to remain in a dormant state within the human body. This is called latency and is a characteristic of the herpes viruses, including Epstein–Barr virus, which causes glandular fever, and varicella zoster virus, which causes chickenpox and shingles. Most people have been infected with at least one of these types of herpes virus. These latent viruses might sometimes be beneficial, as the presence of the virus can increase immunity against bacterial pathogens, such as Yersinia pestis.Some viruses can cause lifelong or chronic infections, where the viruses continue to replicate in the body despite the host's defence mechanisms. This is common in hepatitis B virus and hepatitis C virus infections. People chronically infected are known as carriers, as they serve as reservoirs of infectious virus. In populations with a high proportion of carriers, the disease is said to be endemic.

Question: What does the Epstein-Barr virus cause?
Answer: glandular fever

Question: What are the common hepatitis virus strains in humans?
Answer: hepatitis B virus and hepatitis C virus
Native American populations were devastated by contagious diseases, in particular, smallpox, brought to the Americas by European colonists. It is unclear how many Native Americans were killed by foreign diseases after the arrival of Columbus in the Americas, but the numbers have been estimated to be close to 70% of the indigenous population. The damage done by this disease significantly aided European attempts to displace and conquer the native population.A pandemic is a worldwide epidemic. The 1918 flu pandemic, which lasted until 1919, was a category 5 influenza pandemic caused by an unusually severe and deadly influenza A virus. The victims were often healthy young adults, in contrast to most influenza outbreaks, which predominantly affect juvenile, elderly, or otherwise-weakened patients. Older estimates say it killed 40–50 million people, while more recent research suggests that it may have killed as many as 100 million people, or 5% of the world's population in 1918.Most researchers believe that HIV originated in sub-Saharan Africa during the 20th century; it is now a pandemic, with an estimated 38.6 million people now living with the disease worldwide. The Joint United Nations Programme on HIV/AIDS (UNAIDS) and the World Health Organization (WHO) estimate that AIDS has killed more than 25 million people since it was first recognised on 5 June 1981, making it one of the most destructive epidemics in recorded history. In 2007 there were 2.7 million new HIV infections and 2 million HIV-related deaths.

Question: What was the ranking of the flu pandemic that was unusually deadly and may have killed  as many as 5% of the worlds population?
Answer: category 5
Opinions differ on whether viruses are a form of life, or organic structures that interact with living organisms. They have been described as "organisms at the edge of life", since they resemble organisms in that they possess genes, evolve by natural selection, and reproduce by creating multiple copies of themselves through self-assembly. Although they have genes, they do not have a cellular structure, which is often seen as the basic unit of life. Viruses do not have their own metabolism, and require a host cell to make new products. They therefore cannot naturally reproduce outside a host cell—although bacterial species such as rickettsia and chlamydia are considered living organisms despite the same limitation. Accepted forms of life use cell division to reproduce, whereas viruses spontaneously assemble within cells. They differ from autonomous growth of crystals as they inherit genetic mutations while being subject to natural selection. Virus self-assembly within host cells has implications for the study of the origin of life, as it lends further credence to the hypothesis that life could have started as self-assembling organic molecules.

Question: what is it that viruses do not have?
Answer: hey do not have a cellular structure
Replication of viruses involves primarily multiplication of the genome. Replication involves synthesis of viral messenger RNA (mRNA) from "early" genes (with exceptions for positive sense RNA viruses), viral protein synthesis, possible assembly of viral proteins, then viral genome replication mediated by early or regulatory protein expression. This may be followed, for complex viruses with larger genomes, by one or more further rounds of mRNA synthesis: "late" gene expression is, in general, of structural or virion proteins.

Question: Viruses are invasive because of the replication that occurs with what messenger protein?
Answer: RNA
Several highly lethal viral pathogens are members of the Filoviridae. Filoviruses are filament-like viruses that cause viral hemorrhagic fever, and include ebolaviruses and marburgviruses. Marburg virus, first discovered in 1967, attracted widespread press attention in April 2005 for an outbreak in Angola. Ebola Virus Disease has also caused intermittent outbreaks with high mortality rates since 1976 when it was first identified. The worst and most recent one is the West Africa epidemic.

Question: What does Filoviruses cause?
Answer: viral hemorrhagic fever
The rate or speed of transmission of viral infections depends on factors that include population density, the number of susceptible individuals, (i.e., those not immune), the quality of healthcare and the weather.Epidemiology is used to break the chain of infection in populations during outbreaks of viral diseases. Control measures are used that are based on knowledge of how the virus is transmitted. It is important to find the source, or sources, of the outbreak and to identify the virus. Once the virus has been identified, the chain of transmission can sometimes be broken by vaccines. When vaccines are not available, sanitation and disinfection can be effective. Often, infected people are isolated from the rest of the community, and those that have been exposed to the virus are placed in quarantine. To control the outbreak of foot-and-mouth disease in cattle in Britain in 2001, thousands of cattle were slaughtered. Most viral infections of humans and other animals have incubation periods during which the infection causes no signs or symptoms. Incubation periods for viral diseases range from a few days to weeks, but are known for most infections. Somewhat overlapping, but mainly following the incubation period, there is a period of communicability—a time when an infected individual or animal is contagious and can infect another person or animal. This, too, is known for many viral infections, and knowledge of the length of both periods is important in the control of outbreaks. When outbreaks cause an unusually high proportion of cases in a population, community, or region, they are called epidemics. If outbreaks spread worldwide, they are called pandemics.

Question: What is the term used for international widespread outbreaks of viral infections?
Answer: pandemics
There are many types of plant virus, but often they cause only a loss of yield, and it is not economically viable to try to control them. Plant viruses are often spread from plant to plant by organisms, known as vectors. These are normally insects, but some fungi, nematode worms, and single-celled organisms have been shown to be vectors. When control of plant virus infections is considered economical, for perennial fruits, for example, efforts are concentrated on killing the vectors and removing alternate hosts such as weeds. Plant viruses cannot infect humans and other animals because they can reproduce only in living plant cells.Plants have elaborate and effective defence mechanisms against viruses. One of the most effective is the presence of so-called resistance (R) genes. Each R gene confers resistance to a particular virus by triggering localised areas of cell death around the infected cell, which can often be seen with the unaided eye as large spots. This stops the infection from spreading. RNA interference is also an effective defence in plants. When they are infected, plants often produce natural disinfectants that kill viruses, such as salicylic acid, nitric oxide, and reactive oxygen molecules.Plant virus particles or virus-like particles (VLPs) have applications in both biotechnology and nanotechnology. The capsids of most plant viruses are simple and robust structures and can be produced in large quantities either by the infection of plants or by expression in a variety of heterologous systems. Plant virus particles can be modified genetically and chemically to encapsulate foreign material and can be incorporated into supramolecular structures for use in biotechnology.

Question: What kind of worms are vectors?
Answer: nematode
Viruses are an established cause of cancer in humans and other species. Viral cancers occur only in a minority of infected persons (or animals). Cancer viruses come from a range of virus families, including both RNA and DNA viruses, and so there is no single type of "oncovirus" (an obsolete term originally used for acutely transforming retroviruses). The development of cancer is determined by a variety of factors such as host immunity and mutations in the host. Viruses accepted to cause human cancers include some genotypes of human papillomavirus, hepatitis B virus, hepatitis C virus, Epstein–Barr virus, Kaposi's sarcoma-associated herpesvirus and human T-lymphotropic virus. The most recently discovered human cancer virus is a polyomavirus (Merkel cell polyomavirus) that causes most cases of a rare form of skin cancer called Merkel cell carcinoma.

Question: What type of cancers happen in a small portion of infected people?
Answer: Viral
Viruses may have once been small cells that parasitised larger cells. Over time, genes not required by their parasitism were lost. The bacteria rickettsia and chlamydia are living cells that, like viruses, can reproduce only inside host cells. They lend support to this hypothesis, as their dependence on parasitism is likely to have caused the loss of genes that enabled them to survive outside a cell. This is also called the degeneracy hypothesis, or reduction hypothesis.

Question: If viruses were once small cells, as hypothesized by some, what was it that they parasitised?
Answer: larger cells

Question: What was their hypothesis on?
Answer: parasitism
By the early 1980s, the concept had broadened from agricultural systems design towards sustainable human habitats. After Permaculture One, Mollison further refined and developed the ideas by designing hundreds of permaculture sites and writing more detailed books, such as Permaculture: A Designers Manual. Mollison lectured in over 80 countries and taught his two-week Permaculture Design Course (PDC) to hundreds of students. Mollison "encouraged graduates to become teachers themselves and set up their own institutes and demonstration sites. This multiplier effect was critical to permaculture’s rapid expansion."The permaculture movement also spread throughout Asia and Central America, with Hong Kong-based Asian Institute of Sustainable Architecture (AISA), Rony Lec leading the foundation of the Mesoamerican Permaculture Institute (IMAP) in Guatemala and Juan Rojas co-founding the Permaculture Institute of El Salvador.

Question: What was Mollison's claim to fame?
Answer: designing hundreds of permaculture sites
Several individuals revolutionized the branch of permaculture. In 1929, Joseph Russell Smith added an antecedent term as the subtitle for Tree Crops: A Permanent Agriculture, a book which sums up his long experience experimenting with fruits and nuts as crops for human food and animal feed.  Smith saw the world as an inter-related whole and suggested mixed systems of trees and crops underneath. This book inspired many individuals intent on making agriculture more sustainable, such as Toyohiko Kagawa who pioneered forest farming in Japan in the 1930s.In Australian P. A. Yeomans' 1964 book Water for Every Farm, he supports the definition of permanent agriculture, as one that can be sustained indefinitely. Yeomans introduced both an observation-based approach to land use in Australia in the 1940s and the Keyline Design as a way of managing the supply and distribution of water in the 1950s.

Question: What was the Keyline Design used for in terms of agriculture in the 1950s?
Answer: managing the supply and distribution of water

Question: What types of systems did Smith suggest?
Answer: mixed systems of trees and crops underneath
The term permaculture was developed and coined by David Holmgren, then a graduate student at the Tasmanian College of Advanced Education's Department of Environmental Design, and Bill Mollison, senior lecturer in Environmental Psychology at University of Tasmania, in 1978.  The word permaculture originally referred to "permanent agriculture", but was expanded to stand also for "permanent culture", as it was understood that social aspects were integral to a truly sustainable system as inspired by Masanobu Fukuoka’s natural farming philosophy.

Question: What was peraculture originally reffered to?
Answer: permanent agriculture
The Venera 12 (Russian: Венера-12 meaning Venus 12) was a Soviet unmanned space mission to explore the planet Venus. Venera 12 was launched on 14 September 1978 at 02:25:13 UTC.Separating from its flight platform on December 19, 1978, the lander entered the Venus atmosphere two days later at 11.2 km/s. During the descent, it employed aerodynamic braking followed by parachute braking and ending with atmospheric braking. It made a soft landing on the surface at 06:30 Moscow time (0330 UT) on 21 December after a descent time of approximately 1 hour. The touchdown speed was 7–8 m/s. Landing coordinates are 7°S 294°E. It transmitted data to the flight platform for 110 minutes after touchdown until the flight platform moved out of range while remaining in a heliocentric orbit. Identical instruments were carried on Venera 11 and 12.

Question: How fast did the Venera 12 lander go when entering the atmosphere of the second planet of the solar system?
Answer: 11.2 km/s
At the Congress of Vienna, Frederick William's ministers succeeded in securing important territorial increases for Prussia, although they failed to obtain the annexation of all of Saxony, as they had wished. Following the war, Frederick William turned towards political reaction, abandoning the promises he had made in 1813 to provide Prussia with a constitution.

Question: Who secured the Prussian territory?
Answer: Frederick William's
In 1813, following Napoleon's defeat in Russia, Frederick William turned against France and signed an alliance with Russia at Kalisz, although he had to flee Berlin, still under French occupation. Prussian troops played a key part in the victories of the allies in 1813 and 1814, and the King himself travelled with the main army of Prince Schwarzenberg, along with Alexander of Russia and Francis of Austria.

Question: What city did Frederick William have to run away from?
Answer: Berlin
In this period, Wiman Joseon expanded to control a vast territory and became strong economically by controlling trade between the Han Dynasty and the peoples of Manchuria. Emperor Wu of Han thought that Wiman Joseon increasingly threatened Han China, and Wiman Joseon would ally with the Xiongnu.

Question: Who would WIman Joseon side with?
Answer: Xiongnu
Several nations were formed in its place. Among them was the Nangnang Nation. The Nangnang Nation must be differentiated from the Lelang commandery.

Question: how many nations were formed from this place?
Answer: Several
Gnaeus Cornelius Scipio Calvus, with 20,000 infantry (2 Roman and 2 allied legions) 2,200 cavalry and 60 quinqueremes, sailed from Massilia and landed at Emporiae in Iberia. The Greek cities of Emporiae and Tarraco welcomed the Romans, and Gnaeus began to win over the Iberian tribes north of the Ebro. Hasdrubal Barca, after being warned of the Roman expedition, marched north with an army of 8,000 foot soldiers and 1,000 cavalry to join Hanno.

Question: Approximately how many different legions did Gnaesus sail with?
Answer: 2 Roman and 2 allied legions
Hanno had been completely surprised by the Roman arrival in Iberia. Seeing the grip of the Carthaginians on the newly conquered Iberian tribes loosening because of the activities of Scipio, he decided to offer battle. Hanno marched and attacked the Romans just north of Tarraco, near a place called Cissa or Kissa. There were no brilliant manoeuvres or ambushes, the armies formed up and faced off. Being outnumbered two to one, Hanno was defeated relatively easily, losing 6,000 soldiers in battle. Furthermore, the Romans managed to capture the Carthaginian camp, along with 2,000 more soldiers and Hanno himself. The camp contained all the baggage left by Hannibal. The prisoners also included Indibilis, an influential Iberian chieftain who would cause severe trouble for the Romans later. The Romans also stormed the town of Cissa, though to the frustration of the Romans it did not contain any valuable booty.

Question: The Carthaginian camp had whose baggage?
Answer: Hannibal
While Hannibal was marching through Gaul, Scipio had landed with his army at the allied Greek city of Massilia. He then sent a cavalry patrol north, up the eastern bank of the Rhone River, which clashed with a similar force of Numidian light cavalry and, after a hard fought skirmish, drove off the Carthaginians. Scipio marched north from his base, while Hannibal marched east towards the Alps. Arriving at the deserted Carthaginian camp, Scipio learned that Hannibal was three day's march away and decided to send his forces to Iberia under the command of his elder brother Gnaeus, who had been consul in 221 BC, while he himself returned to Northern Italy to organize the defences against Hannibal.

Question: Who commanded the fighting men in Massilia while Hannibal was in Gaul?
Answer: Scipio
Since independence, Botswana has had one of the fastest growth rates in per capita income in the world. Botswana has transformed itself from one of the poorest countries in the world to an upper middle-income country. Although Botswana was resource-abundant, a good institutional framework allowed the country to reinvest resource-income in order to generate stable future income. By one estimate, it has the fourth highest gross national income at purchasing power parity in Africa, giving it a standard of living around that of Mexico.The Ministry of Trade and Industry of Botswana is responsible for promoting business development throughout the country. According to the International Monetary Fund, economic growth averaged over 9% per year from 1966 to 1999. Botswana has a high level of economic freedom compared to other African countries. The government has maintained a sound fiscal policy, despite consecutive budget deficits in 2002 and 2003, and a negligible level of foreign debt. It earned the highest sovereign credit rating in Africa and has stockpiled foreign exchange reserves (over $7 billion in 2005/2006) amounting to almost two and a half years of current imports.

Question: How much in value did the foreign exchange reserves produce?
Answer: over $7 billion
The judiciary is independent of the executive and the legislature. Botswana ranks 28th out of 167 states in the 2018 Democracy Index. According to Transparency International, Botswana is the least corrupt country in Africa and ranks close to Portugal and South Korea.It consists of a typical court system of local Magistrates Courts, a High Court and a Court of Appeal. The High Court is a superior court of record with unlimited original jurisdiction to hear and determine any criminal, civil or constitutional cases under any law. Appeals can be heard by the Court of Appeal. The Head of the High Court is the Chief Justice.The Court of Appeal is the highest and final court in the country and deals with appeals from the High Court and the Industrial Court. The Head of the Court of Appeal is the Judge President.

Question: is the judiciary dependent?
Answer: The judiciary is independent
The presidency passed to the sitting Vice-President, Quett Masire, who was elected in his own right in 1984 and re-elected in 1989 and 1994. Masire retired from office in 1998. He was succeeded by Festus Mogae, who was elected in his own right in 1999 and re-elected in 2004. The presidency passed in 2008 to Ian Khama (son of the first President), who had been serving as Mogae's Vice-President since resigning his position in 1998 as Commander of the Botswana Defence Force to take up this civilian role.

Question: When did Masire retire from office?
Answer: 1998
