Read the following paragraph and find out where the topic sentence is. Even when we are very careful in the thing we do each day, the risk of loss and injury is always with us. Starting the day with a shower, we risk sleeping and falling through the glass door. Riding to work, we risk collision. While we are away from our homes, the risk of fire and burglary is greater. Going to school, our children risk of being injured. We also loss through unintentional actions of our own that might injure others. Such events may occur regardless of how careful we may try to be, and they can cost us a lot of money. Rather than taking the chance of being wiped out financially, we transfer some or our risks to others, we buy insurance.
