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.

Let me give you an 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

(CNN) More Americans than at any time in Barack Obama's presidency now say that things in the United States are going well, a sharp uptick in positive views and the best reviews of the country's trajectory since January 2007, according to the latest CNN/ORC poll. Overall, 54% say things in the country today are going well, 46% badly. That's a reversal from late July when 54% said things were going poorly and 46% said they were positive. The improvement in impressions of the country's path stems largely from shifts among Democrats and independents. Among Democrats, 85% say things are going well, up from 76% in late July. Among independents, 51% now say things are going well, up 9 points since this summer. There's been no significant shift, however, among Republicans: 21% now say things are going well, not significantly different from the 17% who said so in July.54% to 46% say things in the country are going well compared to badlyThat's a reversal from late July
