题目解析:
根据early exhibitors定位到第一第二句话: Although early exhibitors regularly accompanied movies with live acts, the substance of the movies themselves is mass-produced, prerecorded material that can easily be reproduced by theaters with little or no active participation by the exhibitor. Even though early exhibitors shaped their film programs by mixing films and other entertainments together in whichever way they thought would be most attractive to audiences or by accompanying them with lectures, their creative control remained limited.第一句话中的live acts对应C选项,但是C选项和原文锚段,原文说是伴随电影的,而后半句更是强调可以没有active participation,所以C错;而第二句话说:早期放映者试图将电影和其他娱乐元素结合起来,对应A选项,正确。
