QUES: The "Mittelschule" is a school in some States of Germany that offers regular classes and remedial classes but no college preparatory classes. In some States of Germany, the Hauptschule does not exist, and any student who has not been accepted by another school has to attend the Mittelschule. Students may be awarded the Hauptschulabschluss or the Mittlere Reife but not the Abitur.
What kind of classes are offered in Mittelschule?

QUES: The 2011 Business Software Alliance Piracy Study Standard, estimates the total commercial value of illegally copied software to be at $59 billion in 2010, with emerging markets accounting for $31.9 billion, over half of the total. Furthermore, mature markets for the first time received less PC shipments than emerging economies in 2010, making emerging markets now responsible for more than half of all computers in use worldwide. In addition with software infringement rates of 68 percent comparing to 24 percent of mature markets, emerging markets thus possess the majority of the global increase in the commercial value of counterfeit software. China continues to have the highest commercial value of such software at $8.9 billion among developing countries and second in the world behind the US at $9.7 billion in 2011. In 2011, the Business Software Alliance announced that 83 percent of software deployed on PCs in Africa has been pirated (excluding South Africa).
Who accounted for less than half the total?

ANS: unanswerable

QUES: In the wake of the discovery, there was much nationalistic rivalry between the French and the British over who deserved credit for the discovery. Eventually, an international consensus emerged that both Le Verrier and Adams jointly deserved credit. Since 1966, Dennis Rawlins has questioned the credibility of Adams's claim to co-discovery, and the issue was re-evaluated by historians with the return in 1998 of the "Neptune papers" (historical documents) to the Royal Observatory, Greenwich. After reviewing the documents, they suggest that "Adams does not deserve equal credit with Le Verrier for the discovery of Neptune. That credit belongs only to the person who succeeded both in predicting the planet's place and in convincing astronomers to search for it."
Who questioned the credibility of Adam's claim in the 19th century?

QUES: 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.
What do birds bathe in?

ANS:
water or dust
