I'm taking a test and have to guess the right answer to the question after the article. Article: Are you worried by the rising crime rate? If you are, you probably know that your house, possessions and person are increasingly in danger of suffering from great rise in the cases of burglary(;) and attack. Figures show an ever-increasing crime rate, but it is only too easy to imagine "It will never happen to me". Unfortunately, statistics show that it really can happen to you and, if you live in a large city, you run twice the risk of being a victim. Fortunately, there is something definite which you can do. Protect Alarms can help to protect your house with a burglar alarm system which is effective, simple to operate and easily affordable. You must remember that owning a burglar alarm is no indication that your house is packed with valuable possessions. It quite simply indicates to unwelcome visitors that yours is one house they will not break into easily, so they carry on to an unprotected house where their job is made a lot easier.
