Question: Could a small force of American soldiers have prevented Iraq from sliding back into chaos , as Governor Bush claims ? 
The exchange started like this : at the end of Jeb Bush 's town-hall meeting in Reno , Nevada , on Wednesday , a college student named Ivy Ziedrich stood up and said that she had heard Bush blame the growth of ISIS on President Obama , in particular on his decision to withdraw American troops from Iraq in 2011 . 
The origins of ISIS , Ziedrich said , lay in the decision by Bush 's brother , in 2003 , to disband the Iraqi Army following the toppling of Saddam Hussein 's government . 
Wow ," Bush said . 
Here is what happened : In 2003 , the U.S. military , on orders of President Bush , invaded Iraq , and nineteen days later threw out Saddam 's government . 
Historians -- along with Governor Bush and Ivy Ziedrich -- will be arguing about the question for a long time . 
"All right ," Bush said . 
Bush Administration officials involved in the decision -- like Paul Bremer and Walter Slocombe -- argued that they were effectively ratifying the reality that the Iraqi Army had already disintegrated . 
But the Bush White House went ahead . 
While it 's true that George W. Bush took actions that helped enable the creation of the Iraqi insurgency , and that some leaders of the insurgency formed ISIS , it 's not true that he "created" ISIS . 
And there 's a good argument to be made that an insurgency would have formed following the invasion of Iraq even if President Bush had kept the Iraqi Army together . 
Indeed , by 2011 the situation in Iraq -- as former Governor Bush said -- was relatively stable . 
But let 's get to Governor Bush 's assertion -- that Iraq went down the tubes because of President Obama 's decision to pull out all American forces , and that Obama could easily have left behind a residual force that would have kept the peace . 
"When we left Iraq , security had been arranged ," Bush said . 
A few days after that , President Bush or someone in his Administration decreed the dissolution of the Iraqi Army . 
Bush did n't like it : he offered a retort and then left the stage . 
So , on this , Governor Bush is n't entirely accurate , but makes a good point : the Obama Administration might have been able to keep some forces in Iraq if it had really tried .

Answer: George W Bush


Question: After enduring one too many maddeningly slow boarding experiences  Jason Steffen a professor of physics and astronomy at the University of Nevada Las Vegas  began digging into the unexpectedly complicated mechanics of efficiently ushering passengers onto planes.
In 2008   Steffen  created a computer simulation to evaluate existing boarding methods and ultimately design what  he  claims is the most efficient option for getting restless passengers into their seats. The results were published several years ago in the Journal of Air Transport Management (summarized here).
In  his  research   Steffen  identified the two most common factors responsible for slowing the boarding process to a painful crawl:
In fact  the most routine boarding process â from back to front â is actually the slowest of them all   Steffen âs argues  Itâs even less efficient than boarding a plane in a completely random order.
 Steffen  claims that  his  proposed method  which minimizes the former issue and eliminates the latter  could significantly reduce boarding times  thus cutting down on overall door-to-door flight lengths  and ultimately saving airlines hundreds of millions of dollars a year.

Answer: Jason Steffen


Question: Fernando Solorzano   head of Panamaâs Merchant Marine  told Reuters there was no initial sign that the stricken ship was in breach of any security protocols.  He  added  though  that investigations could take months or even years to conclude.
âIt had all the valid technical certificates on board and the financial guarantees required under international agreements â  Solorzano  said in an interview late on Thursday.
An international team of experts from China  Iran  Hong Kong and the crewâs home countries would be analyzing the voyage data recorder  a device that monitors the vesselâs progress  to determine the cause of the collision   he  added.
 Solorzano  said all vessels sailing under the flag had to comply with strict requirements.  He  conceded the event could adversely affect the image of the registry because it is known for having a low rate of incidents.

Answer:
Fernando Solorzano
