Sentence 1: The terror attacks, it was clear, had blasted a hole in the dam holding back Mumbai's reservoir of woes. While the protesters seemed to be reacting to a tragedy that had left at least 164 people dead and 308 injured, they were really venting the frustrations of having to cope with life in a city with an infrastructure so stretched that simply getting to work and back is an ordeal. At peak hour, the commuter trains - which carry six million people each day - are packed with up to 5,000 commuters, even though they're built for 1,800. Sentence 2: The Mumbai attacks claimed at least 164 lives.
