Input: Read this: However, Eritrea still faces many challenges. Despite number of physicians increasing from only 0.2 in 1993 to 0.5 in 2004 per 1000 population, this is still very low. Malaria and tuberculosis are common in Eritrea. HIV prevalence among the 15–49 group exceeds 2%. The fertility rate is at about 5 births per woman. Maternal mortality dropped by more than half from 1995 to 2002, although the figure is still high. Similarly, between 1995 and 2002, the number of births attended by skilled health personnel has doubled but still is only 28.3%. A major cause of death in neonates is by severe infection. Per capita expenditure on health is low in Eritrea.
Question: In 2004, how many physicians did Eritrea have per 1000 people?

Output: 0.5


QUES: Pitt's Act was deemed a failure because it quickly became apparent that the boundaries between government control and the company's powers were nebulous and highly subjective. The government felt obliged to respond to humanitarian calls for better treatment of local peoples in British-occupied territories. Edmund Burke, a former East India Company shareholder and diplomat, was moved to address the situation and introduced a new Regulating Bill in 1783. The bill was defeated amid lobbying by company loyalists and accusations of nepotism in the bill's recommendations for the appointment of councillors.

What kind of calls did the government ignore?
What is the answer?

The South American highlands were a center of early agriculture. Genetic testing of the wide variety of cultivars and wild species suggests that the potato has a single origin in the area of southern Peru, from a species in the Solanum brevicaule complex. Over 99% of all modern cultivated potatoes worldwide are descendants of a subspecies indigenous to south-central Chile, Solanum tuberosum ssp. tuberosum, where it was cultivated as long as 10,000 years ago. According to George Raudzens, "It is clear that in pre-Columbian times some groups struggled to survive and often suffered food shortages and famines, while others enjoyed a varied and substantial diet." The persistent drought around 850 AD coincided with the collapse of Classic Maya civilization, and the famine of One Rabbit (AD 1454) was a major catastrophe in Mexico.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What event in 850 AD coincided with the collapse of Mayan civilization?
Ah, so.. persistent drought


Question: By 59 BC an unofficial political alliance known as the First Triumvirate was formed between Gaius Julius Caesar, Marcus Licinius Crassus, and Gnaeus Pompeius Magnus ("Pompey the Great") to share power and influence. In 53 BC, Crassus launched a Roman invasion of the Parthian Empire (modern Iraq and Iran). After initial successes, he marched his army deep into the desert; but here his army was cut off deep in enemy territory, surrounded and slaughtered at the Battle of Carrhae in which Crassus himself perished. The death of Crassus removed some of the balance in the Triumvirate and, consequently, Caesar and Pompey began to move apart. While Caesar was fighting in Gaul, Pompey proceeded with a legislative agenda for Rome that revealed that he was at best ambivalent towards Caesar and perhaps now covertly allied with Caesar's political enemies. In 51 BC, some Roman senators demanded that Caesar not be permitted to stand for consul unless he turned over control of his armies to the state, which would have left Caesar defenceless before his enemies. Caesar chose civil war over laying down his command and facing trial.
Try to answer this question if possible: Who started the invasion of the Parthian Empire?
Answer: Crassus


Context and question: There is evidence of induced copper deficiency in those taking 100–300 mg of zinc daily. A 2007 trial observed that elderly men taking 80 mg daily were hospitalized for urinary complications more often than those taking a placebo. The USDA RDA is 11 and 8 mg Zn/day for men and women, respectively. Levels of 100–300 mg may interfere with the utilization of copper and iron or adversely affect cholesterol. Levels of zinc in excess of 500 ppm in soil interfere with the ability of plants to absorb other essential metals, such as iron and manganese. There is also a condition called the zinc shakes or "zinc chills" that can be induced by the inhalation of freshly formed zinc oxide formed during the welding of galvanized materials. Zinc is a common ingredient of denture cream which may contain between 17 and 38 mg of zinc per gram. There have been claims of disability, and even death, due to excessive use of these products.
Having an excess of 500ppm of zinc in soil interferes with what?
Answer:
ability of plants to absorb other essential metals
