The GDP of Thuringia is below the national average, in line with the other former East German Lands. Until 2004, Thuringia was one of the weakest regions within the European Union. The accession of several new countries, the crisis in southern Europe and the sustained economic growth in Germany since 2005 has brought the Thuringian GDP close to the EU average since then. The high economic subsidies granted by the federal government and the EU after 1990 are being reduced gradually and will end around 2020.
What has helped to improve Thuringia? 
A: The accession of several new countries, the crisis in southern Europe and the sustained economic growth

Melatonin is absent from the system or undetectably low during daytime. Its onset in dim light, dim-light melatonin onset (DLMO), at roughly 21:00 (9 p.m.) can be measured in the blood or the saliva. Its major metabolite can also be measured in morning urine. Both DLMO and the midpoint (in time) of the presence of the hormone in the blood or saliva have been used as circadian markers. However, newer research indicates that the melatonin offset may be the more reliable marker. Benloucif et al. found that melatonin phase markers were more stable and more highly correlated with the timing of sleep than the core temperature minimum. They found that both sleep offset and melatonin offset are more strongly correlated with phase markers than the onset of sleep. In addition, the declining phase of the melatonin levels is more reliable and stable than the termination of melatonin synthesis.
When is Meletonin found in the system?
A: unanswerable

Nearly two billion people in the developing world are deficient in zinc. In children it causes an increase in infection and diarrhea, contributing to the death of about 800,000 children worldwide per year. The World Health Organization advocates zinc supplementation for severe malnutrition and diarrhea. Zinc supplements help prevent disease and reduce mortality, especially among children with low birth weight or stunted growth. However, zinc supplements should not be administered alone, because many in the developing world have several deficiencies, and zinc interacts with other micronutrients.
Why shouldn't zinc be given alone to those with no deficiencies?
A: unanswerable

The constitution for independent Swaziland was promulgated by Britain in November 1963 under the terms of which legislative and executive councils were established. This development was opposed by the Swazi National Council (liqoqo). Despite such opposition, elections took place and the first Legislative Council of Swaziland was constituted on 9 September 1964. Changes to the original constitution proposed by the Legislative Council were accepted by Britain and a new constitution providing for a House of Assembly and Senate was drawn up. Elections under this constitution were held in 1967.
