Question: Feathers being critical to the survival of a bird, require maintenance. Apart from physical wear and tear, feathers face the onslaught of fungi, ectoparasitic feather mites and birdlice. The physical condition of feathers are maintained by preening often with the application of secretions from the preen gland. Birds also bathe in water or dust themselves. While some birds dip into shallow water, more aerial species may make aerial dips into water and arboreal species often make use of dew or rain that collect on leaves. Birds of arid regions make use of loose soil to dust-bathe. A behaviour termed as anting in which the bird encourages ants to run through their plumage is also thought to help them reduce the ectoparasite load in feathers. Many species will spread out their wings and expose them to direct sunlight and this too is thought to help in reducing fungal and ectoparasitic activity that may lead to feather damage.
Try to answer this question if possible: What do birds bathe in?
Answer: water or dust
Question: Rainfall tends to be associated with Atlantic depressions or with convection. The Atlantic depressions are more vigorous in autumn and winter and most of the rain which falls in those seasons in the south-west is from this source. Average annual rainfall is around 980 millimetres (39 in). November to March have the highest mean wind speeds, with June to August having the lightest winds. The predominant wind direction is from the south-west.
Try to answer this question if possible: From what direction do most of the winds blow on Plymouth?
Answer: south-west
Question: Glass is in widespread use largely due to the production of glass compositions that are transparent to visible light. In contrast, polycrystalline materials do not generally transmit visible light. The individual crystallites may be transparent, but their facets (grain boundaries) reflect or scatter light resulting in diffuse reflection. Glass does not contain the internal subdivisions associated with grain boundaries in polycrystals and hence does not scatter light in the same manner as a polycrystalline material. The surface of a glass is often smooth since during glass formation the molecules of the supercooled liquid are not forced to dispose in rigid crystal geometries and can follow surface tension, which imposes a microscopically smooth surface. These properties, which give glass its clearness, can be retained even if glass is partially light-absorbingi.e., colored.
Try to answer this question if possible: What does glass lack, allowing it to be polycrystalline?
Answer: unanswerable
Question: An exception to the usual European qualification system happened in 2005, after Liverpool won the Champions League the year before, but did not finish in a Champions League qualification place in the Premier League that season. UEFA gave special dispensation for Liverpool to enter the Champions League, giving England five qualifiers. UEFA subsequently ruled that the defending champions qualify for the competition the following year regardless of their domestic league placing. However, for those leagues with four entrants in the Champions League, this meant that if the Champions League winner finished outside the top four in its domestic league, it would qualify at the expense of the fourth-placed team in the league. No association can have more than four entrants in the Champions League. This occurred in 2012, when Chelsea who had won the Champions League the previous year, but finished sixth in the league qualified for the Champions League in place of Tottenham Hotspur, who went into the Europa League.
Try to answer this question if possible: Which team received special dispensation from the UEFA in 2005 so they could enter the Champions League?
Answer:
Liverpool
