Teacher: In this task, you will be presented with a passage and have to answer a question based on your understanding of the events inferred from the passage. Among the entities, try to find the best entity that is most likely to fill in "_" and classify the answers based on options.
Teacher: Now, understand the problem? If you are still confused, see the following 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 
 Questions:Under the terms of the agreement any cubs will return to _ at the age of two, the age at which they would normally leave their mother in the wild. (A) Tian Tian (B) UK (C) Edinburgh Zoo (D) Sweetie (E) Yang Guang (F) China
Solution: (F)
Reason: This is a good example. Based on the passage, any cubs will return to China at the age of two

Now, solve this instance: A wave of migrants 4,500 years ago left their trace in the DNA and languages of modern Europeans. This is according to a study that found evidence of this Stone Age migration by analysing DNA of 69 people who lived across Europe between 8,000 and 3,000 years ago. Among the shifts in the genetic make-up of ancient Europeans they found that DNA associated with the Yamnaya people appeared strongly in what is now northern Germany. Researchers have identified a mass migration of Kurgan populations (Yamna culture) which went from the Russian steppes to the centre of Europe 4,500 years ago. Previously, researchers had believed it spread 8,500 years ago, when the first farmers from the Near East, now modern day Turkey, brought it to EuropeStudy looked at DNA of Europeans who lived 8,000 and 3,000 years agoDNA associated with Yamnaya people appeared in northern GermanyYamnaya were herders from the steppe north of the Black and Aral SeasThis suggests a large influx that would have changed speech and DNAPreviously, researchers believed that Indo-European language spread some 8,500 years ago, by the first farmers from the Near East, now Turkey 
 Questions:Although genes can't determine what people spoke, the researchers argue that their findings could influence the debate about the origins of _ tongues. (A) Europeans (B) Stone Age (C) DNA (D) Europe (E) Yamnaya (F) Germany (G) Kurgan (H) Yamna (I) Russian (J) Near East (K) Turkey (L) Black (M) Aral (N) Indo-European
