Example Input: Leading up to the Olympic figure skating menâs event   Nathan Chen  was a gold medal favorite.  Chen âs teammate Adam Rippon  who does not perform some of the more difficult jumps that  Chen  does  wasnât considered a true threat for a medal in the olympic skating menâs event  but managed to endear  himself  to the world with  his  exuberant â and clean â skate.
Now Rippon sits ahead of  Chen  after the Olympic figure skating menâs short program. Ripponâs error-free skate  albeit minus the quad jumps  landed  him  in seventh place while teammate Vincent Zhou is in 12th.  Chen   who made mistakes on all of  his  jumps  is currently 17th. That means  he  will skate in the second group of six skaters in the free program tomorrow  since the skating order is reversed from the rankings after the short program.
 Chen   who is competing in  his  first Olympics  is having a tough time so far. First there was his error-filled short program in the team skating event earlier this week  in which he botched all of his jumps. Then he did the same in the menâs short program.
 Chen âs arsenal of quadruple jumps sets  him  apart from most of the competition; quadruple jumps are worth far more in points than triples are  and itâs easy for  Chen  to add up points and pull away from the field â if  he  lands them cleanly.
The disastrous short program prompted tweets of encouragement for  Chen   including from Olympian Scott Hamilton. âI respect you. I admire you. I believe in you. Today was a difficult day. Tomorrow is up to you!â
But even if  Chen  skates a dazzling long program peppered with multiple quad jumps  itâs numerically impossible for  him  to climb from 17th place into medal contention â unless most of  his  higher-ranking competitors all come down with the norovirus. âIâve never been in this position before so I donât really know exactly what to do â  he  says.
Even before the menâs short began  Olympian and silver medalist Paul Wylie questioned the fluidity and uncertainty of so much of todayâs Olympic athletesâ schedules.  Chen  has said  he  regularly changes the elements of  his  program  switching jumps depending on how  he  is feeling and whether  he  needs to perform the more challenging ones to game a competition. âI am not a fan of the ultra fluidity of the planned program content â Wylie said. â Nathan  is dealing with a lot of variables. The other variable is  Nathan  is always talking about  his  boots;  he âs got three different pairs of boots. And  he  has been going away [from Gangneung] to practice. So  he âs thinking  where am I practicing today. Iâm not sure those question marks are really what you need in the Olympics.â
Maybe what  Chen  needs is some of teammate Ripponâs infectious exuberance. âIâm able to go out in the individual menâs event and show the world I am a cutthroat competitor and that Iâm an awesome skater â Rippon says. âAnd I want to show why everyone should be involved in skating because it is something that has brought me so much joy  and can bring a lot of other people a lot of joy as well.â

Example Input: Alabama Democratic U.S. Senate hopeful  Doug Jones  says  he  is a âright-to-liferâ once a baby is born  but â before then â  he  supports abortion up until the day of birth.
 Jones  told MSNBCâs MTP Daily host Chuck Todd:
When Todd asked him if he would not support legislation that banned late-term abortions   Jones  replied:
 Jones  faces Republican candidate Judge Roy Moore in a special election on December 12 to fill the Senate seat previously held by now-Attorney General Jeff Sessions.
 Doug Jones  clearly has no problem with the fact that the U.S. is only one of seven nations â alongside North Korea and China â to allow elective abortion on-demand after five months.  His  extremism puts  him  dramatically out of step with Alabama voters. Alabama is one of twenty states to take a stand against the brutality of late term abortions having approved a state limit in 2011. Polls consistently show that a large majority of Americans â women in higher numbers than men â support bringing our national laws into line with basic human decency  and the House will vote on this measure next week.  Jones  is out to impress the big abortion lobby but this does nothing for  his  chances against Judge Moore.
Example Output: Doug Jones

Example Input: That meant the billâs passage was not assured in the House of Representatives and would need some Democratic support.  Speaker Paul Ryan  a Republican who has backed the agreement   predicted the chamber would pass the budget deal.
âI think we will â  Ryan  told radio host Hugh Hewitt. âThis is a bipartisan bill. Itâs going to need bipartisan support. We are going to deliver our share of support.â
In an appeal to Democrats to vote for the budget deal   Ryan  repeatedly said during a news conference that  he  would bring an immigration bill to the House floor after the spending measures are enacted. But  he  fell short of the unconditional guarantee that many Democrats demand.
Representative Luis Gutierrez  one of the leading advocates in Congress for immigrants  urged colleagues to reject the deal. âDonât collude with this administration â  he  said. âVote against the budget.â
