Critical Reasoning: Boldface Type Questions

Disease Z is a medical condition which is transmitted by an airborne virus. The Epidemic Control Center of Country X has conducted tests in all the countries in the breakout area of Disease Z and found that countries that had a popular public transportation system suffered from a higher rate of infections. Therefore, it was determined that countries with advanced mass transit systems are more liable to experience a breakout of Disease Z. However, it is also known that all of these countries have a good health system which is able to prevent a breakout by quickly identifying the first infections.
