Article: Zinc chemistry is similar to the chemistry of the late first-row transition metals nickel and copper, though it has a filled d-shell, so its compounds are diamagnetic and mostly colorless. The ionic radii of zinc and magnesium happen to be nearly identical. Because of this some of their salts have the same crystal structure and in circumstances where ionic radius is a determining factor zinc and magnesium chemistries have much in common. Otherwise there is little similarity. Zinc tends to form bonds with a greater degree of covalency and it forms much more stable complexes with N- and S- donors. Complexes of zinc are mostly 4- or 6- coordinate although 5-coordinate complexes are known.

Question: Whit what donors does zinc form stable complexes?
Ans: N- and S-

Article: In a study published in the Journal of Behavioural and Experimental Economics, and reported on in early May 2014, researchers from the University of Portsmouth in the UK discussed findings from examining the illegal downloading behavior of 6,000 Finnish people, aged seven to 84. The list of reasons for downloading given by the study respondents included money saving; the ability to access material not on general release, or before it was released; and assisting artists to avoid involvement with record companies and movie studios.

Question: How many people were part of the study?
Ans: 6,000

Article: An earthquake emergency relief team of 184 people (consisting of 12 people from the State Seismological Bureau, 150 from the Beijing Military Area Command, and 22 from the Armed Police General Hospital) left Beijing from Nanyuan Airport late May 12 in two military transport planes to travel to Wenchuan County.

Question: How many of the team were from the military?
Ans: 150

Article: Switzerland has four official languages: principally German (63.5% total population share, with foreign residents, in 2013); French (22.5%) in the west; and Italian (8.1%) in the south. The fourth official language, Romansh (0.5%), is a Romance language spoken locally in the southeastern trilingual canton of Graubunden, and is designated by Article 4 of the Federal Constitution as a national language along with German, French, and Italian, and in Article 70 as an official language if the authorities communicate with persons who speak Romansh. However, federal laws and other official acts do not need to be decreed in Romansh.

Question: What is the least popular official language of Switzerland?
Ans:
Romansh
