in, with, out; test, testing, tested During the 54-minute flight from Montreal’s Dorval airport to Toronto, the first class cabin was filled _________ reporters and photographers _________the still-evolving technology.
【正确答案】：with，testing
【题目解析】：be filled with 是固定词组，fill in/out 主动语态是填写的意思，不符合上下文的意思。第二个空的词应该是主动语态，因为后面有宾语，因此第二个空填写testing。
