Example Input: And with a mangled racket and plenty of kicking and screaming  including a couple of arguments with the chair umpire  then a postmatch parting shot at a line judge Safin called "a little bit too blind."
 Safin used to rant about disliking tennis on grass  and he once complained about the high price and low quality of food at the players' restaurant at the All England Club. Well  he doesn't have to worry about any of that again after bowing out in his final Wimbledon with a 6-2  3-6  7-6 (4)  6-4 loss to Levine.
 After confirming this would be his last appearance at the grass-court Grand Slam tournament -- Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
 "He's an amazing player  and I'm still kind of feeling weird right now that I just beat Safin  because I've always watched him play on TV " said Levine  who turned pro in 2007. "I just kind of went out there with nothing to lose and played some good tennis."
 Levine was a teen when Safin burst onto the scene as a brash  big-hitting 20-year-old who knocked off Sampras to win the U.S. Open.
 "I really had to ... focus on playing against the ball and not worrying about  'Oh  wow  I'm playing against Marat Safin on the other side of the court '" Levine said. "Because then things could have gotten a lot more interesting."
 As is his wont  Safin made things interesting enough. In the early going  he broke his racket by spiking it on the court.
 Leading 4-3 in the third-set tiebreaker  Safin hit a shot near a line that was ruled out. Afterward  Safin said: "Thanks for the guy who made the call. I want to say hello to him. Too bad that he was a little bit too blind."
 In the fourth set  Safin told the chair umpire he could check for chalk on the ball to confirm a call. Rebuffed  Safin added: "So all players are stupid?"
 Safin reached at least the semifinals at all four majors  including at Wimbledon last year  but he has been criticized for not living up to the potential stored in his 6-foot-4 (1.93-meter) frame -- about 7 inches (18 centimeters) taller than Levine.
 "In the history of tennis  everybody's an underachiever " Safin said. "Agassi should have been winning  I don't know  15 Grand Slams. Sampras should have been winning 20 Grand Slams. Federer should be winning -- already should have 25."
 "I should probably have (won) a couple of more " he said  "but I'm pretty satisfied with what I did."

Example Input: On Thursday morning   President Trump  made a remarkable statement: The government couldnât keep federal disaster relief efforts running in Puerto Rico forever. There would need to be some limit   he  hinted in a string of tweets  tied to a dollar amount set by Congress.
The impression left by the tweets was that Trumpâs patience with the disaster in Puerto Rico had run out  that it was time to start winding things down and to let the island fend for itself. Contrast that with  his  assertion to Texas and Louisiana after Hurricane Harvey struck in September.
Texas & Louisiana: We are w/ you today  we are w/ you tomorrow  & we will be w/ you EVERY SINGLE DAY AFTER  to restore  recover  & REBUILD! pic.twitter.com/YQb82K2VSB â Donald J. Trump (@realDonaldTrump) August 30  2017
That contrast is not new.  Trump  downplayed the looming disaster in Puerto Rico from the outset.
Before Harvey threatened the Gulf Coast and Hurricane Irma hit Florida   Trump  was providing constant updates on  their  approach and immediate aftermath on Twitter  marveling at the stormsâ destructive power and offering praise for those responding to the storm.  He  spent  his  weekends at the White House and Camp David  helping to coordinate operations.
Before Hurricane Maria hit Puerto Rico   Trump  tweeted twice.
 He  spent the weekend  it  hit at  his  club in Bedminster  N.J.  â and the following weekend there  too. Last weekend  he  was at the White House â save for several trips to  his  golf course in Virginia.
As criticism of Trumpâs handling of Maria started to mount  Trumpâs first response was a string of tweets in which  he  criticized the islandâs âmassive debt.â  He  began to turn  his  attention to the crisis on the island  scheduling a day-long visit and praising the work of federal employees who were already on the ground.
But everything was tinged with defensiveness.  He  repeatedly reminded people that Puerto Rico was harder to get to than Texas. Praise for first responders was levied with critiques of the âfake newsâ for also covering the numerous problems Puerto Ricans faced.
Fake News CNN and NBC are going out of their way to disparage our great First Responders as a way to "get Trump." Not fair to FR or effort! â Donald J. Trump (@realDonaldTrump) September 30  2017
Despite the Fake News Media in conjunction with the Dems  an amazing job is being done in Puerto Rico. Great people! â  Donald J. Trump (@realDonaldTrump) September 30  2017
 Insistences that things were going well sat next to insults aimed at a politician who had been critical of  Trump  for the lack of resources in  her  city.
The Mayor of San Juan  who was very complimentary only a few days ago  has now been told by the Democrats that you must be nasty to  Trump .  â Donald J. Trump (@realDonaldTrump) September 30  2017
 â¦Such poor leadership ability by the Mayor of San Juan  and others in Puerto Rico  who are not able to get their workers to help. Theyâ¦.  â Donald J. Trump (@realDonaldTrump) September 30  2017
 Note the comment about Puerto Rican workers in that last tweet. Over the weekend   Trump  tweeted a video showing all the hard work that federal workers were doing.
Nobody could have done what Iâve done for #PuertoRico with so little appreciation. So much work! pic.twitter.com/k2jAkIpfjI â Donald J. Trump (@realDonaldTrump) October 8  2017

Example Input: MUHORONI   Kenya  (Reuters) -  Kenya ’s repeat presidential election  boycotted this week by millions  has reignited long-running tensions between ethnic communities in some areas  leading inhabitants of one small village in the west to pick up traditional arms on Saturday.
On one side of Koguta are Kalenjins  here ardent supporters of President Uhuru Kenyatta and his Kalenjin deputy  William Ruto. But the Luos across the road support opposition leader Raila Odinga  who called for a boycott of the vote because he said it would not be fair.
In Thursday’s vote   Kenyatta  only faced six minor candidates  none of whom won more than 1 percent in August  and that and the low turnout have quashed  his  hopes of securing a decisive mandate to lead east Africa’s richest economy.
Deputy president William Ruto   Kenyatta ’s running mate  told CNN on Saturday he expected the final tally from the vote to be ready by Sunday:
