[EX Q]: Sarah Shourd was freed in September and returned to the United States. Her fiance  Shane Bauer  and their friend Josh Fattal remain in prison.
 Shourd and their families have denied they did anything wrong. After her release  Shourd said they were hiking in a scenic and relatively peaceful part of northern Iraq and inadvertently crossed an unmarked border with Iran when they were arrested in July 2009.
 Iranian authorities said they freed Shourd as a humanitarian gesture because of unspecified health concerns  though the woman has since said her health is fine.
 Iran warned that it will seize the $500 000 bail posted by Shourd if she does not return for trial.
 The 32-year-old Shourd  from Oakland  California  has not disclosed any plans to return to Iran.
 She said in an interview published Oct. 31 in The New York Times that the three stepped off an unmarked dirt road and inadvertently crossed from Iraq only because a border guard of unknown nationality gestured for them to approach.

[EX Q]: "Millennials are making really good decisions whenever they have an opportunity to save more  " Arielle O'Shea   retirement and investing specialist at NerdWallet  told Business Insider.
"Millennials are doing themselves a big service here by saving so early and taking advantage of compound interest  " O'Shea  said.
 It 's possible older Americans aren't saving as much because the cost of raising kids increases the older they get   O'Shea  said  especially when parents "start feeling the crunch of college."
"Everyone can use strategies millennial parents are using  " O'Shea  said. "Save more when you get a raise  when you pay off debt  or cut back on dining."
That's great for some people   O'Shea  said  but "knowing how much you need to be saving is huge  and working toward a goal makes all the difference."

[EX Q]: Enjoy.com CEO and  founder Ron Johnson  thinks Amazon should be really worried about competitor Walmart  but could fight back with another big acquisition.
"I think this is a decade-long price fight. Every quarter is a new round  but Walmart's coming back "  Johnson  said on CNBC's "Fast Money."
The former J.C. Penney CEO has been bullish on Walmart since at least February  when he appeared on "Fast Money" and called the big box retailer's rally. On Thursday  Walmart shares had their best day in nine years. With stock up 44 percent year-to-date  Walmart appeared to confirm  Johnson 's predictions that it could be Amazon's biggest threat.
Amazon may be growing fast  but  Johnson  thinks Walmart has a decided advantage with its preexisting brick-and-mortar infrastructure.  He  explained that most Americans live near a Walmart where they can buy most of what is available on Amazon.
And  Johnson  maintains that Amazon's distribution centers are more expensive and less efficient to run than Walmart's store and warehouses.
"They forward deploy inventory into things called warehouses  that are really stores. They are a lower cost operation than amazon's distribution centers  " Johnson  said.
As for Amazon   Johnson  thinks acquisitions like Whole Foods  are a good move for the internet retailer. And Target is right on brand.
"Whole Foods is to grocery  what Target is to mass. It's the upscale discounter "  he  said.
While  Johnson  doesn't anticipate that mega-acquisition anytime soon   he  said  he  does think Target has all the right amount of space in all the right places for Amazon to stay on top of the competition.
"Target's got 1 500 stores on Main and Main of every city in the country  " Johnson  said.
