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

This is a good example. Based on the passage, any cubs will return to China at the age of two

New input case for you: (CNN) Republicans are finally on the verge of enacting a signature legislative achievement. It's something that seemed up in the air less than 24 hours before the vote, unlikely just a few months ago and completely unfathomable despite bold claims to the contrary midway through President Donald Trump's first year in office. Yet the Republican-controlled US Senate, by a vote of 51-49, early Saturday morning passed a historic overhaul of the US tax code, clearing what has long been considered the largest and most byzantine hurdle in an effort that hasn't been completed in more than 31 years. "We have an opportunity now to make America more competitive, and to keep jobs from being shipped offshore and provide substantial relief to the middle class," McConnell told reporters after the vote. "At the end, there was not a single Democrat who thought this was a good idea, and so we're going to take this message to the American people a year from now."Despite the hurdles facing the Senate tax plan, only one Republican voted against itSens. Rob Portman, Orrin Hatch, Tim Scott and Pat Toomey lobbied hard for the bill 
 Questions:"We have a once-in-a-lifetime opportunity to reclaim _'s great destiny," the statement read, adding that the administration looked forward to enacting the legislation by year's end. (A) CNN (B) Republicans (C) Donald Trump (D) Republican (E) US Senate (F) US (G) America (H) McConnell (I) Democrat (J) Senate (K) Sens (L) Rob Portman (M) Orrin Hatch (N) Tim Scott (O) Pat Toomey
Output:
(G)
