Example Input: American Sage Kotsenburg won gold in the event at the Sochi Games in 2014. We brought him into the âOlympics Cornerâ today for his thoughts on how to watch. Keep scrolling to read that Q&A.
Throughout the Games  weâll occasionally bring someone in to help us better understand the Olympics. Today:  Sage Kotsenburg .
Four years ago in Sochi   Sage Kotsenburg  shocked the snowboarding world by winning slopestyle gold.  He  followed that up with what President Barack Obama told  him  was the âchillestâ interview of the Olympics.  Kotsenburg  has since stopped competing  so  he  wonât be in PyeongChang. But The Post caught up with  him  by phone during a recent film shoot in Italy to get  his  thoughts on this yearâs slopestyle event (8 p.m. Eastern time Saturday on NBCSN).
A: Three people that I would look for are an American kid  Red Gerard.  He âs absolutely crushing it right now. This course  when I saw it  I immediately thought Red can really do well here. I wouldnât be surprised to see  him  on the podium  if not up in the top five.
And then Mark McMorris  who got bronze last time around.  He  came back from a really  really bad injury  so Iâd like to see  him  do good  too. Weâve been good friends for a long time.  He âs crushing it  too.  He âs doing a really  really  really good job right now. Iâd like to see  him  up there.
Iâll give a prediction for gold: Itâs going to be Marcus Kleveland.  He âs from Norway.  He  has pretty much anything you want in a slopestyle course and more. So  if  he  puts down  his  run   he âll probably win or silver  Iâd guess.

Example Input: NEW ORLEANS (Reuters) -  Hurricane Nate  made landfall near the mouth of the Mississippi River as a Category 1 storm with winds of 85 miles per hour on Saturday evening  threatening parts of Louisiana  Mississippi and Alabama with torrential rain and potential flooding.
Nate  the fourth major storm to strike the United States in less than two months  killed at least 30 people in Central America before entering the warm waters of the Gulf and bearing down on the U.S. South.
As the hurricane struck at about 7 p.m. CDT (0000 GMT Sunday)  the National Hurricane Center (NHC) downgraded its warning for New Orleans to a tropical storm. But  Nate  was expected to regain some strength and make a second landfall along the coast of Mississippi to the east.

 Nate  comes on the heels of three other major storms  Harvey  Irma and Maria  which devastated Texas  Florida and Puerto Rico  respectively. But as a Category 1  the weakest in the five-category ranking used by meteorologists   Nate  appeared to lack the devastating punch of its predecessors.

Major shipping ports across the central U.S. Gulf Coast were closed to inbound and outbound traffic on Saturday  as  Nate  intensified and storm surges of up 11 feet (3.74 m) were expected at the mouth of the Mississippi River.
Before heading north into the Gulf   Nate  brushed Mexicoâs Yucatan peninsula  home to beach resorts such as Cancun and Playa del Carmen  the NHC said.

Example Input: SAN FRANCISCO (Reuters) - Uber Technologies Incâs [UBER.UL] fractured board declared peace on Tuesday  attempting to put months of strife behind it by unanimously passing a series of measures to shore up corporate governance  bring in major investor SoftBank and diminish the power of former Chief Executive Travis Kalanick.
 Kalanick  described Tuesdayâs actions as âa major step forward in Uberâs journey to becoming a world class public company.â He added that the governance changes should serve Uber well under Dara Khosrowshahi  who is a month into the chief executive officer job since leaving the same post at Expedia Inc (EXPE.O).
Governance policies adopted by the board would make it difficult for  Kalanick  to return as CEO. He resigned in June under pressure from the Benchmark-led investor group over employee sexual harassment investigations  a trade-secrets misappropriation lawsuit by Waymo and efforts to interfere with government probes.
Uberâs board will expand from 11 directors  including a pair of  Kalanick  appointees seated on Monday  to 17 directors  the person and another source said.
 Kalanick  and other early shareholders also are sacrificing voting power  as Uber adopts a one vote per share policy  the sources said.
