Namibia is the driest country in sub-Saharan Africa and depends largely on groundwater. With an average rainfall of about 350 mm per annum, the highest rainfall occurs in the Caprivi in the northeast (about 600 mm per annum) and decreases in a westerly and southwesterly direction to as little as 50 mm and less per annum at the coast. The only perennial rivers are found on the national borders with South Africa, Angola, Zambia, and the short border with Botswana in the Caprivi. In the interior of the country surface water is available only in the summer months when rivers are in flood after exceptional rainfalls. Otherwise, surface water is restricted to a few large storage dams retaining and damming up these seasonal floods and their runoff. Thus, where people don't live near perennial rivers or make use of the storage dams, they are dependent on groundwater. The advantage of using groundwater sources is that even isolated communities and those economic activities located far from good surface water sources such as mining, agriculture, and tourism can be supplied from groundwater over nearly 80% of the country.
What is the record least amount of rain in a year in the Caprivi?
A: unanswerable

The team placed fifth in the Premier League automatically qualifies for the UEFA Europa League, and the sixth and seventh-placed teams can also qualify, depending on the winners of the two domestic cup competitions i.e. the FA Cup and the Capital One Cup (League Cup). Two Europa League places are reserved for the winners of each tournament; if the winner of either the FA Cup or League Cup qualifies for the Champions League, then that place will go to the next-best placed finisher in the Premier League. A further place in the UEFA Europa League is also available via the Fair Play initiative. If the Premier League has one of the three highest Fair Play rankings in Europe, the highest ranked team in the Premier League Fair Play standings which has not already qualified for Europe will automatically qualify for the UEFA Europa League first qualifying round.
How many Europa League places are reserved for domestic tournament winners?
A: Two

The French Marines and naval infantry intended for the invasion of northern Germany were dispatched to reinforce the French Army of Chalons and fell into captivity at Sedan along with Napoleon III. A shortage of officers, following the capture of most of the professional French army at the Siege of Metz and at the Battle of Sedan, led naval officers to be sent from their ships to command hastily assembled reservists of the Garde Mobile. As the autumn storms of the North Sea forced the return of more of the French ships, the blockade of the north German ports diminished and in September 1870 the French navy abandoned the blockade for the winter. The rest of the navy retired to ports along the English Channel and remained in port for the rest of the war.
The French navy fell captive where?
A:
at Sedan
