Directiоns: Identify the tоpic sentence in the fоllowing pаrаgrаph. The United States has a severe fire problem that if not addressed, will continue to worsen drastically. Fire statistics show that our nation, one of the richest and most technologically sophisticated countries in the world, lags behind its peer nations in fire security. Nationally, there are millions of fires, thousands of deaths, tens of thousands of injuries, and billions of dollars lost each year—figures which far exceed comparable statistics for other industrialized countries. In 2001, for example, the direct value of property destroyed in fires was $11 billion ($44 billion if the World Trade Center loss is included). More recently in 2004, direct property losses from fires were estimated at over $9.8 billion.
