Questions 11 to 13 are based on the following introduction to Dr C. Henry Taylor. You now have 15 seconds to read Questions 11 to 13.
It is a great honor for me to introduce today’s guest lecturer, Dr C. Henry Taylor, a colleague who is so well-known to all of us for his many accomplishments and contributions to the field of architecture and planning that it hardly seems necessary to recount them here. Nevertheless, as customary, I will summarize his long experience as a prelude to his address. Dr Taylor received his BA degree in urban history at Yale University in 1955. Five years later, he was awarded a master degree in architecture and a PhD in urban design from Cornell University. Upon graduating, he accepted a teaching position in the Department of Architecture and Fine Arts at Illinois University where he was promoted to chairman of the department in 1969. Last year Dr Taylor resigned from the University in order to accept a research position with the Departme
A. Urban planning.
B. Trends in urban design.
C. Functional architecture,
D. Federal regulations for urban development.
