标题: PREP SC1 81 无法理解PREP的解释

81.(28921-!-item-!-188;#058&003760)

In the major cities of industrialized countries at the end of the nineteenth century, important public places such as theaters, restaurants, shops, and banks had installed electric lighting, but electricity was in less than one percent of homes, where lighting was still provided mainly by candles or gas.

(A) electricity was in less than one percent of homes, where lighting was still

(B) electricity was in less than one percent of homes and lighting still

(D) there was less than one percent of homes that had electricity, having lighting that was still

(E) less than one percent of homes had electricity, where lighting had still been

两个问题：1. A里为什么要用in less than one percent of homes? in 在这里的意思是什么啊，不明白

2. PREP对B项的解释是第二个was在这里不能省略，说前面的was是助动词，后面的was是系动词，这是什么意思，不明白

问题1：先看 in ......... homes, 再看less than one percent of ，你就明白了。

2. 第一个was是表存在地点，第二个was是被动语态的was。前后用法不一致，不符合省略原则。
