Construct diagrams of the following arguments. Make sure that you explicitly state what each number stands for by writing it out in full (e.g. 1=..., 2=...), and that you are completely clear about what each arrow points to. If you are typing your answers, feel free to use underline to indicate dependent premises, and to use /, , and | in place of arrows, if arrows are difficult on your word processor.
1. A single payer healthcare system is morally necessary for two reasons. First, with any other health care system, the least well off are unable to get the care that they need, and we are morally obligated to care for the least well off. Second, if it has been proven that universal healthcare systems significantly reduce the cost of healthcare, and the skyrocketing healthcare costs are crippling our economy.
2. We shouldn't eat meat because animals are capable of feeling pain and we shouldn't eat anything that is capable of feeling pain.
3. Our latest innovative product has flopped when put on the market. Therefore, we should expect some change of personnel in the marketing division and some new funding in R&D to develop another new product. If there is indeed extra funding in R&D, then we'll be able to hire some extra talent, and if we are able to make new R&D hires, then I think I'll be able to get you a job. All this is to say that I think you'll be getting an offer to work with us.
4. All the evidence suggests that it was Billy who committed the crime. His hair was found at the crime scene. He was seen fighting with the victim just prior to the when the victim went missing. Finally, we found a receipt in his car for a knife exactly like the one used in the crime, so we can safely assume that he just purchased a weapon very similar to the murder weapon.
5. I'm pretty sure that Oddity Industry's stock is about to plummet. Five days ago, a news story alleged that they had just made a major breakthrough, and ever since, it has risen extremely rapidly, so I think that it only rose because of the news of their "breakthrough". But now another news agency has discovered that the original reporting was flawed.
