[EX Q]: Walmart has joined Dick's Sporting Goods in raising its age restriction for the purchase of firearms to 21 years old  the Bentonville  Arkansas-based mass retailer announced Wednesday night.
Walmart's announcement comes the same day that Pittsburgh-based Dick's Sporting Goods Inc. made a similar move. It said it was ending sales of assault-style rifles  banning the sale of guns to people younger than 21  and ceasing the sale of high capacity magazines.
"Based on what’s happened and looking at those kids and those parents  it moved us all unimaginably  " Dick's Sporting Goods Inc. chairman and CEO Edward Stack  said Wednesday on "Good Morning America."
 He  added  "To think about the loss and the grief that those kids and those parents had  we said  'We need to do something.' And we’re taking these guns out of all of our stores permanently."
Despite the moves by  Dick 's Sporting Goods and Walmart  most firearms are not sold at outdoor specialty retailers like  Dick’s   according to a survey by Fernandina Beach  Florida-based Southwick Associates  a market research firm that specializes in the hunting  shooting  sportfishing  and outdoor recreation markets.

[EX Q]: The newspaper quoted Ma as saying: "Whether there will be reunification as expected by the mainland side depends very much on what is going to unfold in the next decade."
 Although the Presidential Office quickly produced a recording showing that Ma actually said "decades  " the issue is not about "decade" or "decades."
 Ma's major fault lies in his ignorance of Taiwan's independent sovereign status. There is no such issue as unification of the two sides of the Taiwan Strait. The term "unification" is just a term coined by China to camouflage its attempt to annex Taiwan.
 Ma's other mistake is his failure to recognize that only the 23 million people of Taiwan have the right to decide Taiwan's future. Since Taiwan and China are two different countries  China's 1.3 billion people should have no say in determining Taiwan's destiny. It is wrong to say that Taiwan's future would be jointly decided by people on both sides of the strait.
 Most threatening  is that Ma thinks  Taiwan  has resisted unification because "conditions are not ripe...We don't even know each other that well."
 Ma must remember that as a popularly elected president  he is obligated to defend Taiwan's national security and sovereignty. If he fails in his duty and lets the people down  he would be a traitor.

[EX Q]: Tesla Model 3 production really is hell.
 Elon Musk  Tesla’s founder and CEO   warned us in July as  he  delivered the first 30 all-electric Model 3 cars to buyers who also happened to be employees.

On Monday   Tesla  reported  it  has produced just 260 Tesla Model 3 cars   its  first mass-market all-electric sedan  in the last quarter. That’s approximately 120 cars a month  a number that would be less distressing if Musk himself hadn’t predicted producing as many as 20 000 Model 3 cars a month by December of this year.
Tesla reported half a million Model 3 pre-orders in late July. At the company’s current production pace   Tesla  Model 3 customer 500 000 might not see her all-electric sedan until the year 2363.
What’s far more likely is that it will be a few years or more before  Tesla  gets through all  its  orders  and those who ordered first will endure the highest level of frustration as their cars will probably be delayed the most. A lot of people in the middle of the product delivery queue could receive their Model 3’s at the same time and  eventually  ordering a Model 3 could be as easy and commonplace as buying a Ford Focus.

There’s been a lot of calamity in the world in the last few months  but  apparently  it’s not the source of the production issues. “…there are no fundamental issues with  the Model 3 production or supply chain  ”  Tesla  said in the release.

The cause is  Tesla ’s own facilities: “production bottlenecks” at both  its  Fremont production plant and the massive Gigafactory in Nevada.
Considering how much Musk said  Tesla  learned from the production hell it went through with  its  previous  Tesla  models  this is surprising. Musk recalled in July how the Roadster  its first electric car  was the worst. “We went through hell and then actually did a return journey ” Musk said  “We had to redo almost the entire car and recapitalize the company  which sucked.”
There were roughly 30 Model 3's ready to go on July 29.  Tesla  managed to produce another 230 Model 3 cars since then. Image: lance ulanoff/mashable
Doug Field   Tesla ’s VP of Engineering said they designed the Model 3 to move as quickly through production as possible  while maintaining as high production quality as possible.
Where  exactly  those production bottlenecks exist is  since Tesla isn’t saying  anyone’s guess  but it doesn’t take much to slow down a production line like this. As Musk explained in July  “There’s 10 000 unique components in the car and production will move as fast as the slowest one.”
Beyond statements made in the release   Tesla  wouldn't comment on the delays.
No matter where it is  the numbers speak for themselves: 260 Model 3 cars off the production line. Even with an S-Curve  it’s is hard to imagine that in fewer than three months   Tesla  will rocket to 20 000 a month.
