题目解析：
Lecture中出现了传统印度孟加拉式平房的特征是如何变化的内容，因此需要仔细听。这部分介绍到英国人用石头建筑孟加拉式平房，并且在阳台立起柱子。这些都是他们对孟加拉式平方的改造。因此正确答案为A和C。在支柱上面建房是传统的风格,而孟加拉式平房一直以来都是单层建筑,所以BD选项不正确。
【对应原文】
Well, over time, the British started to, um, to change these bungalows so that they looked more like the, um, the houses they were used to in England. So they started having the bungalows made out of, of stone... um, and they added columns to the veranda.
