1. c, Student comprehension is usually equivalent or greater with computer-assisted instruction (CAI). Although many researchers report greater student comprehension with CAI, there are a comparable number that report equivalent scores and a minority of studies that report lower scores. This is an important point for judging the applicability of CAI for osteopathic graduate medical education. Results vary depending on the quality of the CAI product. A well-designed product can bolster student comprehension, or it may simply represent an equivalent replacement or supplement for traditional teaching methods. However, some CAI products are poorly designed and, thus, are inferior to traditional teaching methods.
   
2. d. More than 20 million people are afflicted with asthma in the United States.
   
3. c. It is estimated that 6.2 million children (<18 years) currently have asthma in the United States.
   
4. b, false. Conventional magnetic resonance imaging detects the nuclear magnetic resonance spectra of water in tissues. Magnetic resonance spectroscopy, on the other hand, generally detects the resonance spectra of chemical compounds other than water, allowing for a true depiction of in situ chemistry.
   
5. e, phosphocholine. Breast cancer cells contain at least 10 times more phosphocholine than do normal mammary epithelial cells. Magnetic resonance spectroscopy makes it possible to profile this diagnostic marker for breast cancer. Creatine, lactate, myoinositol, and N-acetylaspartate are all diagnostic markers for brain neoplasms.
