The Simon Commission (1928) is the event linked with Sir John Simon in 1928, since it contained no Indian member and provoked the slogan “Simon Go Back”. On the Simon Commission: the Indian National Congress and other parties boycotted the Commission at every stop it made in India, and the all-party response it triggered led directly to the drafting of the Nehru Report later the same year. The Simon Commission belongs to the 1927-1947 phase of India's national movement, and exam setters often pair the Simon Commission with neighbouring milestones on this timeline to test precise, date-wise recall. Independence Day pledge is incorrect because the Independence Day pledge took place in 1930, not 1928, so it does not fit this question on the Simon Commission. Karachi Session of Congress is incorrect because the Karachi Session of Congress took place in 1931, not 1928, so it does not fit this question on the Simon Commission. Congress Ministries is incorrect because the Congress Ministries took place in 1937, not 1928, so it does not fit this question on the Simon Commission. Competitive exams such as SSC CGL, SSC CHSL, State PSC, and Railway exams frequently test the Simon Commission of 1928, so keeping the year, the key person, and the outcome linked together in memory helps avoid confusion with nearby events in the national movement timeline. Candidates preparing for the Simon Commission question should also revise the events immediately before and after it on the 1927-1947 timeline, since paper-setters frequently frame options using adjacent years and closely related personalities. Remember: Simon Commission — 1928 — Sir John Simon.
