Answer of Section 1, Question 1

For the urban researcher, the long lives of ancient cities can provide ample chronological data, making up for the paucity stemming from the relative ______ of most present-day cities.

官方解說：

The sentence compares the amount of chronological data available to urban researchers. Ancient cities, with their "long lives," naturally provide a lot of data. In order to fill the blank, we need to identify the word that characterizes "most present-day cities” and explains the "pauclty” of data they provide. Since the contrast is with ancient cities, "youthfulness,” is the best fit. No other answer choice would pertain to the paucity of data from present-day cities.

Thus the correct answer is youthfulness.
