Rate the following argument fragment on its writing, argument, and language skills:
Evidence: Multiple times, the author delves into a side-topic as opposed to continuing on with the topic of Venus exploration. They start off the article with two sentences that have no relation to the story, yet confuse readers. The sentences are about Venus' nickname, the "Evening Star", and how even though it is a planet, it is still called this. This is completely irrelevant to exploration, as everyone knows it is a planet, and the "Evening Star" name is never mentioned again. Later on in the passage, the author rambles on about World War II-age computers and how they functioned properly even before the digital age. Once more, this is slightly irrelevant and does not contribute to the story at all except to add another paragraph instead of focusing on the specifics of how NASA is using them to help with Venus.

Score: 2
