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: Washington (CNN) Sen. Elizabeth Warren delivered an unsubtle criticism of former President Barack Obama in an interview published Monday, saying the former president and other politicians are out of touch with "the lived experiences of most Americans." Warren was interviewed by The Guardian while promoting her new book, "This Fight Is Our Fight," amid heavy speculation about her plans for the 2020 presidential election. That speculation was only fanned over the weekend when President Donald Trump, at a rally in Pennsylvania, suggested that Warren would likely be his 2020 opponent. Speaking to the newspaper, Warren first looked back, attempting to diagnose Democrats' failures in the 2016 election.Warren faulted Obama for what she said was an overreliance on statisticsWarren also discussed Democrats' debate over abortion politics 
 Question:But Warren -- perhaps foreshadowing a fault line for _ in 2020 -- told the Guardian she would "probably not" endorse a candidate who opposed abortion rights.
Solution:
Democrats
