From source A, we learn many things about the murders of Tabram and Nicholls, it starts by saying they have "startled" London, the public would not have been expecting these murders conducted with such "extraordinary violence." The two victims are also said to have been the "poorest of the poor" and the murder is said to have had no adequate motive, although the fact the killer had no motive is an assumption made by the newspaper. The Observer also states that an "excess of effort" went into the murders. This is also not the first article written about the murders as it begins with "have so startled London." This implies the newspaper has already written an article on it before; the newspaper refers (rather subjectively) to the Ripper as a demented being, but provides no real information about the circumstances of the murder, a profile of the killer or any other useful information, just objective opinions on the murders.
Question 2.
Sources A, B and C are all very different accounts of the murders, source A is an account in a newspaper with no detail about what happened, source B is a coroners report and provides information about how the victim has been murdered and a small insight into the way the murderer thinks, source C is a report on the state in which Elizabeth Strides body was found and knowledge about the way she was killed. Source C only supports A by confirming she was poor, "there was no money on the body" but apart from that there is no evidence to suggest "he is demented" or he used an "excess of effort" sources A+B are closer to each other, B states there were no meaningless cuts (not demented) and he had "anatomical skill and knowledge" Source A states "extraordinary violence was used but source B states "there are no meaningless cuts, knew how he should use the knife" "no mere slaughterer of animals could have carried out these operations" This gives us a slight insight into how the murdere works, source A doesn't tell us anything about the murderer but because they have no proper evidence they assume he is "a demented being" who uses "extraordinary violence.
