Read the following text from a student essay. How can the writer best improve his or her word choice? Due to its similar size, density, and composition, Venus is often called Earth's twin. Many scientists have a feeling that both planets were once very similar but changed into different things throughout the passage of time. Presently, the differences between these two planets are much more apparent. For one, the thick air all around Venus helps to keep it over six times hotter than Earth. Venus also has more volcanoes than Earth or any other planet in the solar system. In fact, there are more than 1,600 volcanoes on Venus, but most of them are not doing anything.
