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

New input: (CNN) Many Americans struggle to manage the demands of work, family, and wellbeing in their busy lives. They expect us, as US senators, to carry their voices to Washington and craft legislation that is responsive to their concerns. Health care is one of the most urgent issues for American families. It is about ensuring a sick child or elderly parent has the treatment they need. It should have nothing to do with partisan politics. But this year too many Americans have been inundated with headlines about plans to take away their health care, including this week's news that Republicans want to repeal the Affordable Care Act's individual mandate as part of their tax bill. This would lead to an estimated 13 million people losing insurance.Senators: We are proposing a public option that would let people buy into a program run like MedicareIf passed, the legislation would reduce cost and increase options in healthcare 
 Questions:_ want both parties to work together on real solutions that lower costs and increase choice without exploding our debt or upending lives. (A) Americans (B) US (C) Washington (D) Republicans (E) Affordable Care Act (F) Medicare
