Can someone please please help me with this?

Once the symbol of urban violence, New York City is in the midst of a strange and unprecedented transformation. According to the preliminary crime statistics released by the F.B.I. earlier this month, New York has a citywide violent-crime rate that now ranks it a hundred and thirty-sixth among major American cities, on a par with Boise, Idaho. Car thefts have fallen to seventy-one thousand, down from a hundred and fifty thousand as recently as six years ago. Burglaries have fallen from more than two hundred thousand in the early 1980s to just under seventy-five thousand in 1995. Homicides are now at the level of the early seventies, nearly half of what they were in 1990. Over the past two and a half years, every precinct in the city has recorded double-digit decreases in violent crime. Nowhere, however, have the decreases been sharper than in Brooklyn North, in neighborhoods that not long ago were all but written off to drugs and violence. On the streets of the Seven-Five today, it is possible to see signs of everyday life that would have been unthinkable in the early nineties. There are now ordinary people on the streets at dusk — small children riding their bicycles, old people on benches and stoops, and people coming out of the subways alone. “There was a time when it wasn’t uncommon to hear rapid fire, like you would hear somewhere in the jungle in Vietnam,” Inspector Edward A. Mezzadri, who commands the Seventy-fifth Precinct, told me. “You would hear that in Bed-Stuy and Brownsville and, particularly, East New York all the time. I don’t hear the gunfire anymore. I’ve been at this job for one year and twelve days. The other night when I was going to the garage to get my car, I heard my first volley. That was my first time.”
