Step 1: Recall the Komagata Maru incident.
The Komagata Maru was a Japanese steamship chartered by Gurdit Singh to challenge Canada's racially discriminatory immigration laws that targeted South Asians and other non-European migrants.
Step 2: Identify the year.
The ship arrived at Vancouver Harbour on May 23, 1914. After being denied entry and held offshore for two months, it was forced to return to India, leading to the Budge Budge clash in September 1914.
Step 3: Eliminate the distractors.
1905 is too early for this incident. 1919 is the year of the Jallianwala Bagh massacre. 1930 is the year of the Salt March. The Komagata Maru incident firmly belongs to 1914.
