Several measurement methods have been developed to control glare resulting from indoor lighting design. The Unified Glare Rating (UGR), the Visual Comfort Probability, and the Daylight Glare Index are some of the most well-known methods of measurement. In addition to these new methods, four main factors influence the degree of discomfort glare; the luminance of the glare source, the solid angle of the glare source, the background luminance, and the position of the glare source in the field of view must all be taken into account.
What does UGR stand for?
****
The answer: Unified Glare Rating

In the Kingdom of Poland and later in the Polish-Lithuanian Commonwealth, ennoblement (nobilitacja) may be equated with an individual given legal status as a szlachta (member of the Polish nobility). Initially, this privilege could be granted by monarch, but from the 1641 onward, this right was reserved for the sejm. Most often the individual being ennobled would join an existing noble szlachta clan and assume the undifferentiated coat of arms of that clan.
What right was reversed by sijm?
****
The answer: ennoblement

The problem: Answer a question about this article:
The typical image of migration is of northern landbirds, such as swallows (Hirundinidae) and birds of prey, making long flights to the tropics. However, many Holarctic wildfowl and finch (Fringillidae) species winter in the North Temperate Zone, in regions with milder winters than their summer breeding grounds. For example, the pink-footed goose Anser brachyrhynchus migrates from Iceland to Britain and neighbouring countries, whilst the dark-eyed junco Junco hyemalis migrates from subarctic and arctic climates to the contiguous United States and the American goldfinch from taiga to wintering grounds extending from the American South northwestward to Western Oregon. Migratory routes and wintering grounds are traditional and learned by young during their first migration with their parents. Some ducks, such as the garganey Anas querquedula, move completely or partially into the tropics. The European pied flycatcher Ficedula hypoleuca also follows this migratory trend, breeding in Asia and Europe and wintering in Africa.
Where do the dark-eyed junco migrate?
****
The answer:
arctic climates to the contiguous United States
