Rate the following argument fragment on its writing, argument, and language skills:
Concluding Statement: Venus is not worth the time, effort and resources to explore. The planet proves to be too dangerous for mankind and even for machines. Curiosity is not sufficiant enough of a reason to explore and learn about a inhospitable planet unless it is going to benefit mankind more than what it costed to gain that information. The resources that are going to Venus should be redirected to another cause that will benefit society and life as we know it.
