One example: For four years we have waited expectantly for the pitter patter of tiny paws. Soon, that wait could finally be over. Tian Tian, the UK's only female giant panda, has conceived and could give birth to a cub as early as August. However Edinburgh Zoo, where the pandas live, have warned people 'not to get too excited' as the process is 'extremely complex'. Moreover, on the two previous occasions keepers inseminated Tian Tian - whose name means 'Sweetie' - she has failed to produce a panda cub. She was artificially inseminated again in March this year, but keepers at the zoo say implantation - when a fertilised egg attaches to the uterus - has not yet occurred.Tian Tian has conceived and could give birth to a cub as early as AugustShe has been inseminated twice before but so far failed to produce a cubTian Tian and Yang Guang arrived in 2011 from China to great fanfareOn loan at £600k a year, became first giant pandas to live in UK for 17 years

Now, solve this: Last week it looked as though the Balkans would be plunged into conflict once again after two newly formed 'micro states' clashed over a strip of unclaimed 'no man's land'. Admittedly the war of words bore little resemblance to the strife which has torn apart this often restive corner of Europe down the centuries. The Kingdom of Enclava had claimed a patch of territory by the Serbian border - unaware the land had already been staked out a month before by the Principality of Celestinia. Celestinian interim chancellor of foreign affairs Endre Jos, a 39-year-old IT technician, said of the Enclavans: 'If they try to settle there, we will be there, destroying their game.'Kingdom of Enclava claimed patch of territory on Croatia-Serbia border - unaware it had already been staked out by Principality of CelestiniaCelestinia threatened to 'destroy' rival's 'game' in bitter territorial disputeBut Enclavans, from Poland, and Celestinians, from Hungary, have agreed to share 0.3 km sq patch by the Danube - same area as 43 football pitchesCelestinian spokesman: 'Encalvans are friendly, peace and freedom-loving people. I think we can work together and they are Polish, ergo brothers' 
 Questions:But the deal now struck will see _ take a 0.027 sq km (0.116 square-mile) piece of the land at the southwestern tip on which to build their new country. (A) Balkans (B) Europe (C) Kingdom (D) Enclava (E) Serbian (F) Principality (G) Celestinia (H) Celestinian (I) Endre Jos (J) Croatia (K) Serbia (L) Poland (M) Celestinians (N) Hungary (O) Danube (P) Encalvans (Q) Polish
