Read the following article and select the best answer. Article: As millions of playthings are recalled, doctors are reminded that the risks of lead exposure continue for young patients. Lead is such a well-known health - perhaps even contributing to the fall of the Roman Empire- that it came as a shock to discover that toys played by children could contain lead. Doctors are now dealing with the aftershocks. Just how dangerous is this exposure? That's the question physicians are being asked by parents who find a lead-polluted Elmo, of Dora. Millions of others toys, lunch boxes and pieces of jewelry manufactured in China have been recalled because they contain lead either in the paint that coats them or as a component of the plastic used to make the item more flexible. The lead content in some of the toys recalled this summer was 180 times the amount allowed by law. Some pieces of jewelry were almost 100% lead. Experts advise that the items do cause a risk and that doctors should urge parents to check the comprehensive lists of recalled products on the Consumer Product Safety Commission's Web site and return any appearing on those lists to the manufacturers. If exposure is suspected, a blood test is in order . Since there is no safe level of this universal element, the risk face by children for lead poisoning and its accompanying threat of learning disabilities and behavior problems is considerable. Doctors who have toys in their waiting rooms also are advised to see if any of them have been recalled and to check for chipped, flaking paint-even on those that haven't yet been recalled--since new announcements of toy risk continue. Question: Why does the author mention "the fall of the Roman Empire"? - To tell us a strange story. - To warn us to keep away from lead. - To explain why the Roman Empire fell. - To show how terrible lead poisoning is.

The 31-year-old resident of North Little Rock, Arkansas, waited for about six hours at a nearby medical center while the medical staff there called all over town -- even as far away as Dallas and Memphis -- to find a hand surgeon to reattach his finger. Finally, a willing doctor was located in Louisville, Kentucky. But even though Bleed had insurance , he would have to hire a private plane to get himself there, at a cost of $4,300. In the end, he charged the cost to two credit cards, and his finger was saved. His insurance company eventually covered the cost of the plane, but his experience makes people aware of the fact that trauma care in the United States is not only geographically limited, but in many places, non-existent. Only eight states -- New York, New Jersey, Maryland, Illinois, New Mexico, California, Oregon, and Washington -- have local, fully functional trauma systems. The remaining states have partial systems, and 12 -- including Arkansas -- have no trauma system at all. Although the President has signed a bill of $12 million for the purpose of supporting trauma care systems nationwide, many in Congress are unwilling to spend government money for a service they think should be paid for by states, says Wayne Meredith, medical director for trauma programs at the American College of Surgeons. Meanwhile, many states have also failed to find the dollars to support trauma systems. To make matters worse, many people without insurance depend heavily on the emergency care services, placing a huge financial burden on the medical centers that serve them. For the same reason, doctors, too, often go unpaid. They are unwilling to perform emergency care, worsening critical shortages of neurosurgeons, orthopedists, and hand surgeons -- the very types of specialists Bleed needed at short notice. Supporting a trauma care system doesn't take much. A half-penny sales tax in Miami-Dade County makes its outstanding system work. In Arkansas...
