text: The author should have supported the idea that Venus is worth pursuing throughout the article, rather than beginning to support it in the middle. The author wrote plenty of negative facts about Venus in the first few paragraphs, causing the reader to wonder about the safety of "Earth's 'twin'". In order make the main idea clear the author should have listed a few negative things, and then contradicted them with facts and supporting details. This would have made the article stronger, immaculately organized, and more understandable as well. In the 1950's the General Motors created the special test track to use an eleteric cable that sends radio signals from the back of the car to the front of the car to tell people if they are in danger or if they need to taka over of the car! Also in the 1980's automakers used speed sensors at the wheels of the car so that they can use auto brakes. With in 10 years those sensors had become more advance with the Auto driving Cars and help respond to the danger of out-of-control skids or rollovers that may happen in a crash.
