Rate the following argument fragment on its writing, argument, and language skills:
Evidence: With Sulfuric Acid in Venus' atmosphere, and surface temperatures being over 425 degrees Celcius (about 700 K or 800 F) , the likelyhood of humans on Venus is nearly nonexistent to begin with. To combat the hot temperatures and the acidic atmosphere, NASA proposed the idea of a "blimp" that floats above the planet's shell. Although the blimp could survive high in the air, the practicality of if is not present. Having a blimp that cannot touch the planet is not going to help scientific research at all. While being above the clouds of Venus, it is impossible to see the surface with human eyes. Seeing the surface would require technology that uses light from the electromagnetic spectrum with a high frequency and short wavelength. It is also impossible to collect rock samples from the planet for soil examination. This idea would not be beneficial enough for the risk of investing a lot of time and money.
