Part I: Symbolize the following argument into propositional logic. Make sure you use the lexicon provided. Do not assume anything about the validity or invalidity of the arguments, just symbolize them. Always check your answers by translating back into English using the lexicon provided and then compare against the original English if they are not paraphrases, then your answer is wrong. 3. Social peace is guaranteed, and if Gennady Padalky and Sergei Avdeyev on MIR succeed in deploying the Znamya Space Mirror in February 1999, the Space Regatta Consortium (SRC) positions satellites as giant mirrors to illuminate high latitude regions of the Earth in hours after sunset or before sunrise. If the Space Regatta Consortium (SRC) positions satellites as giant mirrors to illuminate high latitude regions of the Earth in hours after sunset or before sunrise, these regions are illuminated during the night by light sources more than ten times as bright as the Full Moon. If these regions are illuminated during the night by light sources more than ten times as bright as the Full Moon, the crime rate falls and the spirits of those who live there is improved. If the spirits of those who live there is improved, some psychiatrists lose their jobs. If social peace is guaranteed, some psychiatrists don't loose their jobs or some police officers don't lose their jobs. If the crime rate falls, some police officers do lose their jobs. Therefore, Gennady Padalky and Sergei Avdeyev on MIR don't succeed in deploying the Znamya Space Mirror in February 1999. (G: Social peace is guaranteed; S: Gennady Padalky and Sergei Avdeyev on MIR succeed in deploying the Znamya Space Mirror in February 1999; C: the Space Regatta Consortium (SRC) positions satellites as giant mirrors to illuminate high latitude regions of the Earth in hours after sunset or before sunrise; I: High latitude regions of the Earth are illuminated during the night by light sources more than ten times as bright as the Full Moon; F: The crime rate falls; R: The spirits of those who live in high latitude regions of the Earth is improved; L: Some psychiatrists lose their jobs; P: Some police officers lose their jobs) 4. Getting an A in logic is necessary and sufficient for receiving a strong letter of recommendation. Receiving a strong letter of recommendation is not necessary for getting into Law School. So, it's not true that if you don't get a "A" in logic, then you don't get into Law School. (G: You get an "A" in logic; R: You received a strong letter of recommendation; L: You get into Law School) Part I: Symbolize the following argument into propositional logic.
