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: How a huge expanse of grassland with black sooty patches appeared in the middle of lush rainforests, has long baffled conservationists. While some experts have argued fires started by the indigenous Pemón people scorched areas of rainforest, others argue that the grassy landscape of the Gran Sabana appeared before humans lived there. Now researchers claim that while manmade fires shaped the landscape, the region was already becoming a savannah. The Gran Sabana is a grassy 'island' in the middle of lush rainforests measuring 4,180 square miles (10,820 square km) where Venezuela meets Guyana and Brazil. Valenti Rull led a team at the Institute of Earth Sciences Jaume Almera in Barcelona, Spain, which examined ancient pollen in lake sediments, New Scientist reported.Scientists from the Institute of Earth Sciences Jaume Almera in Barcelona examined ancient pollen in lake sediments in Gran SabanaSediment showed area in Venezuela was changing to savannah years before people first settled in the area around 12,000 years agoBut the savannah was expanded by fires, which may have been triggered by lightning strikes, or the Pemón people who still light thousands of firesSome experts believe their technique is the best way to manage and protect rainforests from rampant wildfires
