问题 Which war is this passage to mark the anniversary of?
  
Hi, everyone. As we mark the anniversary of the Iraq war, we’re being reminded of all that our soldiers have sacrificed, and what some continue to experience. The scandal at Walter Reed put their suffering into sharp focus. And so was the new study from the Archives of Internal Medicine. The study found that about a third of veterny vets were diagnosed with mental illness or a psycho social disorder, everything from depression and post traumatic stress, to homeless and domestic violence. The highest rate of mental problems is among the youngest -- soldiers between 18 and 24. The doctor who conducted the study says the num-bets may eventually surpass those from Vietnam.
    Bobby Miller, a Vietnam vet and a President of Veterans from America says, "We haven’t even begun to understand the magnitude of this." "Attention," he says, "must be paid. Unless we want a ’lost generation’." I agree. That’s a page from my notebook.
Everybody loves the swimming pool. But how clean is the water in the average backyard or public pool? If you trust chlorine to take care of germs, you’re in for a surprise. Chlorine and other disinfectants do indeed help to clean the water, but some germs can survive in even the best-kept pool. For example, cryptosporidium may live in pool water for several days. Crypto causes a diarrheal illness and may rinse off the bodies of infected people or diapered children into the pool. If you swallow infected pool water, you may become sick. Other germs may live for a few minutes or a few hours in a chlorinated pool: Giardia, Shigella, and E. Coli may cause diarrheal illnesses. Pseudomonas Aeruginosa may cause an ear infection called swimmer’s ear and also a skin infection called "hot tub rash", that is usually associated with very warm pools and spas. While keeping the correct chlorine and PH levels will minimize water-borne illness, prevention is also a good idea.Keep diapered children in the water for only brief periods and keep sick people out of the water altogether. And, don’t ever swallow pool water.

选项 A、Several seconds.
B、Several minutes.
C、Several hours.
D、Several days.
