text: In the second paragraph, the author states "...Often referred to as Earth's twin, Venus is the closest planet to Earth in terms of density and size, and occasionally the closest in distance too.". They are insuring that a helpful reason to research this planet would be because it is similar to earth, and a relative distance away. The author also states that "Venus was probably covered largely with oceans and could have supported various forms of life, just like Earth.". This shows the readers that Venus is worth studying because there may have been life on this planet. Therefore, NASA needs to send researchers to Venus to identify if there is life or not. The author gives another example by referencing Earth-like features to show that thesremay be some form of life or a way of nature, these references include Venus having mountains, valleys, and craters. This validates the authors point well.
