[Q]: (CNN) Fifteen years ago today, on September 11, 2001, members of the Air National Guard leapt into action -- scrambling F-16s, putting their lives at risk, and serving as the vanguard between our country and its enemies. This should come as no surprise. The first American militia, founded in 1636, consistently lives up to the motto "Always Ready, Always There." And while most Americans are aware of the National Guard's valiant contributions on domestic missions -- its effective and rapid response to hurricanes, wildfires and floods -- perhaps the most significant contribution the Guard makes is on the battlefield. Indeed, the National Guard provides a critical link between local communities and American national security.Wendy Anderson: National Guard is more than simply a critical component of our nation's fighting forceIt is also the connective tissue bridging the civil-military divide, she says 
 Question:At 42.6% of the total selected reserve, the Army National Guard represents both the largest segment of the nation's "citizen soldiers," but also a diverse cross section of the _ who serve, and whose families serve alongside them.
[A]: American


[Q]: (CNN) Your "BPA-free" plastic product may be no safer than the product it replaced, says a new UCLA study that analyzed the impact of a common BPA alternative on zebra fish embryos. The study joins a small but growing group of similar research sounding the alarm about so called "BPA-free" alternatives. "Our findings are frightening and important," said senior author and reproductive endocrinologist Nancy Wayne. "Consider it the aquatic version of the canary in the coal mine." After decades of animal research linked BPA (Bisphenol A), a known endocrine disruptor, to problems with brain and reproductive development, early puberty and a rise in breast and prostate cancer, many manufacturers stopped using the chemical to harden plastics, replacing it with "BPA-free" alternatives. The most common replacement is BPS (Bisphenol S), said Wayne.BPA-free alternatives may be no safer than BPA, say researchersMost common alternative, BPS, linked in study to disruptions of estrogen and thyroid hormones 
 Question:In addition to the effect on estrogen, the study also found both _ and BPS affected the thyroid hormone system.
[A]: BPA


[Q]: (CNN) On Saturday morning, most of us laughed off President Donald Trump's Twitter storm accusing former President Barack Obama of wiretapping his phones during the campaign. After all, as noted widely in the media, Trump had offered zero evidence for his bizarre claim. Soon, the jokes were flying at Trump's expense. That evening, on "Saturday Night Live," the show's "Weekend Update" co-anchor Michael Che said it best -- with a bonus reference to Ivanka Trump: "Well, this Saturday morning, while his nurse was at temple, Grandpa shuffled out of his room and got into his Twitter again." All I could think do is wonder is what's next: Trump accusing Obama of being the one who gave Warren Beatty the wrong envelope at the Oscars? Or maybe, even, Trump accusing Obama of killing Tupac?Obeidallah: Jokes about Trump accusing Obama of tapping his phones were everywhereBut his demand that Congress investigate this baseless claim means it's no laughing matter 
 Question:President _'s "request" should send a shiver down the spine of anyone who has any understanding of how dictators work.
[A]:
Donald Trump
