单选题 We can see from the first paragraph that the first Labor Day march ______.

A、 immediately won nationwide support
B、 involved workers from 30 states
C、 was opposed by many factory owners
D、 was organized by the UBCJ

【正确答案】 C

【答案解析】由第一段中对此次游行的描述“an estimated 10，000 workers，many of them ignoring their bosses’warnings，left work to march from Union Square up Fifth Avenue to the 42nd Street”可知，工厂主对此次游行持抵制态度。
