1.Improved technology and equipment often result in fewer injuries during high-risk activities such as rock climbing and scuba diving. But participant education also plays a large role in reducing the number of injuries sustained during these activities. People who are poorly trained in these activities run a much higher risk of injury even if provided with the latest and best equipment. Which of the following can be properly inferred from the information above? A Training is a more important safety factor than equipment in high-risk activities. B People who are properly trained in their activities do not sustain injuries. C The safety benefits of the latest equipment can be offset by inadequate preparation. D Rock climbing and scuba diving are more risky than any other activities. E People with the latest equipment often neglect proper training.
2. The new heart scans offer patients significant benefits. They can be completed in a fraction of the time required for an angiogram, with no recovery time necessary. Furthermore, the scans are more sensitive and can identify problem areas that an angiogram might not perceive. However, heart scans use more radiation than most diagnostic procedures, and can cause undue concern over and treatment for the harmless abnormalities often picked up by such sensitive technology. Which of the following conclusions is best supported by the statements above? A A heart scan is safer than an angiogram procedure. B Patients should not be concerned about heart abnormalities that appear in a heart scan. C A heart scan could result in indirect harm by causing a patient to undergo risky, unnecessary procedures. D An angiogram is the more appropriate of the two procedures for most patients. E The heart scan is a more expensive procedure than the angiogram.
