Answer:
According to Document E, it can be inferred that the Lytton Commission viewed the military operations of the Japanese troops during the Manchurian Incident as not legitimate self-defense, and that the Chinese did not make any authorized or concerted attack on the Japanese forces at the time and place of the incident.
Step-by-step explanation:
According to Document E, the Lytton Commission's attitude to the Manchurian Incident can be inferred as critical and skeptical of Japan's actions. The commission notes that Japan had a carefully prepared plan to meet the case of possible hostilities between themselves and the Chinese, implying that Japan may have been looking for an excuse to take military action. The commission also notes that the Chinese had no plan of attacking the Japanese troops or endangering the lives or property of Japanese nationals at the time of the incident, suggesting that Japan's military operations were not justified.
Furthermore, the commission states that the explosion on or near the railroad, which was the supposed reason for Japan's military action, did not in fact prevent the punctual arrival of the southbound train from Changchun and was not sufficient to justify military action. The commission goes on to say that the military operations of the Japanese troops during the night cannot be regarded as measures of legitimate self-defense, implying that Japan's actions were not justified.
Overall, the language used in Document E suggests that the Lytton Commission was critical of Japan's actions and skeptical of their justifications for military intervention in Manchuria.
