I saw all of these sentences in Economist magazine, 22nd June 2013 edition --
1) The dispute has raised the threat of a snap election in crisis-hit Greece, which could endanger its bail-out programme.
Question: In this case "which" seem to refer to "the threat of a snap election" - but there is "in crisis-hit Greece" phrase" in between too - so may be because of modifier-touch-rule "which" can refer to "crisis-hit Greece". Please clarify ?
2) A parliamentary committee published a long-awaited report into the failings of the British banking system.
Question: Searched on Google for more uses of "report into" idiom -- I did not find many. (One more such use here: http://www.hsj.co.uk/home/francis-report)
Looking at the context - report into X is used where X is some event or phenomenon. And the mentioned report is the explanation of that X. Please clarify ?
3) More than 100 people died in floods in the northern Indian state of Uttarakhand. The flooding, which washed away roads, bridges and houses, has also affected several other states as well as India’s capital, Delhi.
Question: I want to clarify why author has used "flooding" (a gerund noun) rather than more popular noun "flood". Is such use to emphasize that flood or its effect is still going on ? But I seem to be wrong as I have seen other uses of flooding for past events too.
Flooding also temporarily closed part of Route 50 west of Royal Gorge Bridge and Park.
New York Times Aug 11, 2013
The next year Thailand witnessed its worst flooding in half-a-century, inundating 90 billion square kilometers of land.
Time Aug 9, 2013

4) The Los Angeles council approved an ordinance to outlaw plastic supermarket bags, by far the biggest city in America to do so. The measure will come into effect next year and includes a 10-cent charge on paper bags for shoppers who do not bring their own reusable ones.
Two questions --
4.A) How "city" (in bold) can refer to Los Angeles which is not available as noun, but rather as Adjective to the council ?
4.B) 2nd Sentence uses "The measure will come into effect ... and includes ..." -- probably two different tenses are parallel because measure is already defined - so at present also it includes the definition? But, then also those two things does not look parallel to me -- one talks about "coming into effect" and other talks about "the definition of the measure". Please clarify ?
