People on either side of the smartphones-for-teens debate can't agree on the evidence. sure, there's proof of cyber bullying. there's also proof of educational benefits. yet nothing is conclusive, so no valid judgment can be made for everyone on whether smartphones should be banned from teens. anyone supporting such a restriction is naïve and uniformed. he or she is reacting from emotion instead of using his or her brain to study all the evidence and make a decision specific to his or her own teen. the bottom line is it's up to parents to be parents. why spend billions of dollars on trying to stop cyber bullying or explore educational apps? it's probably just another human assumption that we can control the technology we've created. trying is a waste of time and money. which of the following is true about this argument excerpt?

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
