which choice completes the text with the most logical transition?
a previously,
b finally,
c in sum,
d however,

Explanation:

To determine the correct transition, analyze the text structure. The first part lists Medellín's urban design investments (cable cars, libraries, escalators, Parque Biblioteca España). The second part states the results (reduced travel times, lower homicide rates). "In sum" is used to summarize or conclude the effects of the initiatives, fitting the context. "Previously" refers to prior time, "Finally" implies a last item in a sequence (but the results aren’t a final initiative), and "However" introduces contrast (no contrast here). So "In sum" logically connects the initiatives to their outcomes.

Answer:

C. In sum,
