Directions: Complete the following passage by using ONE word that best fits the context.

When Mrs. Joseph Groeger died recently in Vienna, Austria, people asked, "Why did she live to be 107?".   48     were provided by a survey conducted among 148 Viennese men and women who had reached the age of 100. Somewhat surprising was the fact   49     the majority had lived most of their lives in cities.   50     the city's image as an unhealthy place, yet city living often provides benefits that country living can lack. One factor seems to be important to the longevity (长寿) of those interviewed.

This factor is exercise. In the cities it is often faster to walk short distances than   51   wait for a bus. Even taking public transportation often requires some walking. Smaller apartment houses have   52    elevators (电梯), and so people must climb stairs. City people can usually walk to local supermarkets.  53    parking spaces are hard to find, there is often no alternative to walking.

On the other hand, those who live in the   54     and suburbs do not have to walk every day. In fact, the opposite is often true. To go to school, work, or almost anywhere   55    , they must ride in cars.
