Eng112 Laura Funk 10/27/2012 Negative effects of Rap Music on Teenagers I strongly believe that you need to give your children the freedom to make their own choices in the paths they take in their lives. If you don’t they might rebel and make poor choices that can lead to a poor lifestyle. Although you do have to step in every once in a while but I believe you need to make these interferences in their lives a very rare occasion. For instance when it comes to negative rap music and their videos;

An Informative Look at a Financially Successful Future College has always been an important step towards getting into a high paying job. Unfortunately‚ in most states‚ tuition is on the rise and students who do not come from wealthy homes find themselves a step or two behind.

The current gun control laws should be strictly enforced to avoid creating new laws. News laws make it harder on law abiding citizens to purchase firearms‚ ammunition‚ and magazines/clips. Some feel it would decrease gun violence by creating new laws. This is unfair to thousands of people who are gun advocates‚ including myself.

A central organizing concept in biology is that life changes and develops through evolution‚ and that all life-forms known have a common origin. The theory of evolution postulates that all organisms on the Earth‚ both living and extinct‚ have descended from a common ancestor or an ancestral gene pool. This last universal common ancestor of all organisms is believed to have appeared about 3.5 billion years ago.[21] Biologists generally regard the universality and ubiquity of the genetic code as definitive

Do people really need that one extra cent? People normally just leave them on the ground or in a fountain. Some people want to stop minting the penny and to never use it again‚ but others want to keep using the penny and not get rid of it. Some people are fighting to get rid of the penny and these articles may pull people to their side: “Penny Wise‚ or 2.4 Cents Foolish?”(Source 1)‚ “Is the Penny Worth It?”(Source 2)‚ “Give a Penny-Save the Day!”(Source 3)‚ and “The Ever-Changing Penny”(Source 4)
