Question

Experts predict that a future disease outbreak will spread rapidly because

O countries are not stockpiling anti-viral medications
O much of the world's population lives in crowded urban areas
O people travel less often than they used to
more people take daily antibiotics

Answer 1

Based on the given options, the correct answer would be:

much of the world's population lives in crowded urban areas

The close proximity of large numbers of people in urban areas can create conditions that are conducive to the rapid spread of infectious diseases. When people live in crowded areas, they may have more frequent contact with others, which can increase the likelihood of disease transmission. In addition, cities often have large transportation hubs, such as airports and train stations, which can facilitate the movement of people and diseases across large distances.

While the other options listed may also impact the spread of disease in some way, they are not as directly related to the spread of infectious diseases as living in crowded urban areas. The lack of anti-viral medications and overuse of antibiotics, for example, may contribute to the development of drug-resistant strains of bacteria or viruses, but they do not necessarily make the spread of disease more likely. Similarly, decreased travel may actually reduce the spread of disease, rather than increase it.
