Concept:
Many influential books in urban planning and architecture have shaped modern ideas related to city design, human-scale planning, and urban development.
Matching books with their authors is important in planning theory and urban design studies.
Step 1: Match each book with its author.
• A. The Death and Life of Great American Cities
This influential urban planning book was written by Jane Jacobs.
Therefore:
\[
A \rightarrow III
\]
• B. A Pattern Language
This book was written by Christopher Alexander.
Therefore:
\[
B \rightarrow IV
\]
• C. Cities for People
This urban design book focusing on human-centered cities was written by Jan Gehl.
Therefore:
\[
C \rightarrow II
\]
• D. The City of Tomorrow and its Planning
This book was written by Le Corbusier.
Therefore:
\[
D \rightarrow I
\]
Step 2: Identify the correct combination.
Thus, the correct matching is:
\[
A-III,\; B-IV,\; C-II,\; D-I
\]
Therefore, the correct answer is:
\[
{A\text{-}III,\; B\text{-}IV,\; C\text{-}II,\; D\text{-}I}
\]
