1. Experts estimate that insurance companies’ tardiness in paying doctors for legitimate medical claims adds approximately 10 percent in overhead costs for physicians. Insurance companies counter that the tardiness sometimes results from billing errors made by the doctors themselves. Since dealing with these billing errors costs the insurance companies time and money, it is clear that insurance companies do not have a significant economic incentive to delay claim payments to doctors. Which of the following pieces of information, if true, weakens the conclusion above? A Some doctors who submit accurate bills to insurance companies still receive tardy payments. B The cost to the insurance companies to process incorrect bills from doctors’ offices is roughly equivalent to the increased costs that physicians accrue as a result of tardy payments from insurance companies. C A rising proportion of medical claims submitted by doctors to insurance companies are deemed illegitimate by those insurance companies. D The billing errors made by doctors’ offices are typically very minor, such as the submission of a claim with an outdated patient home address. E The overhead costs incurred by doctors as a result of delayed insurance payments result in an increase in the premiums paid by consumers to health insurance companies that far exceeds any increase in the fees paid to doctors by insurance companies.
2.Of the people who moved from one state to another when they retired, the proportion who retired to SunState has decreased by 10 percent over the past five years. Since many local businesses in SunState cater to retirees, this decline is likely to have a noticeably negative economic effect on these businesses. Which of the following, if true, most seriously weakens the argument? A SunState attracts more people who move from one state to another when they retire than does any other state. B There are far more local businesses in SunState that cater to tourists than there are local businesses that cater to retirees. C The number of retirees who have moved out of SunState to accept re-employment in other states has increased over the past five years. D SunState has lower property taxes than any other state, making the state a magnet for retirees. E The total number of people who retired and moved to another state for their retirement has increased significantly over the past five years.
