Compare and Contrast
Comparison of sources Both sources A and B are similar in that there is political repression by British Government. Source A says,"I think you know, when I was elected and appointed Chief Minister, I was told I had no office, no clerk, no thambi." 
This shows that the British Government didn't treat the local government as how they treated the British government, and treated them more lowly than the British government.
 Similarly, source B says,"Out on the streets, Chinese students ignored the government's official closure of their schools, and in a repeat of the previous year locked themselves into their classrooms, where they established their own revolutionary curriculum."
 This shows that the British government didn't respect the rights of the Chinese students, and thus the Chinese students had to protest against the government. The difference in both Sources A and B is the goals for both parties.
In source A, David Marshall aims for independence for Singapore and in Source B the chinese students hopes for their own revolutionary cirriculum.
Source A states that"Merdeka!People of Singapore!"
 This shows he wants the citizens of Singapore to oppose against the rule of the British and self-govern their own country.He wants to unite the citizens of Singapore to establish their own Independence.
 In contrast,Source B states "Chinese students ignored the Government's official closure of their schools , and in repeat of their previos year locked themselves into their classrooms, where they established their own revolutionary cirriculum."
 This shows that the chinese students strongly disagree with the present cirriculum and are revolting by forcibly confining themselves in the classrooms and creating their own cirriculum. Thus both Source A and B are different in terms of goals for Singapore.

On 27 April, the workers continued to block the gate of the bus depot by forming a human barrier. They refused to move despite repeated warnings. The police then used batons to disperse the crowds resulting in 15 people injured. The police action generated sympathy for the workers. Eight hundred SBWU members employed by other companies stopped work between 10 am and 2 pm on that day to protest against “police bullying”.

“The Hock Lee bus riots is a dark reminder of how quickly the radical left could mastermind and unleash chaos. It was an era where chaos and disorder were used as political tools to gain control. But in the midst of hardship and suffering, conflict and sacrifice, Singapore found a way to peace, prosperity, and independence.”

SINGAPORE - Newspaper reports called 1955 "Singapore's blackest year of industrial unrest", with 271 strikes recorded as of November that year.

Using recollections collected by the Oral History Centre of the National Archives, Benita Aw Yeong shows you why Singaporeans have zero tolerance for illegal strikes.

Hock Lee Bus Strikes and Riots
When: May 12, 1955
What happened: A strike broke out at the Hock Lee Bus Company after 200 members of the Singapore Bus Workers' Union were dismissed.

This later erupted into a full-scale riot between the police and striking workers, who were joined by about 2,000 Chinese middle-school students who showed up to lend their support. Four people were killed and 31 were injured. The strike lasted 142 days, making it the longest in post-war Singapore.

"There were demonstrations and riots in Alexandra area where the bus depot was... At the circus, the students put up road blocks and they stood around in a mass. Some of them moved forward... throwing stones, daring the police to retaliate.

"And this went on for about half an hour I think. Then suddenly, there was a fire... word came through the loudspeakers that they'd overturned a car... they were burning the car and attacking the passengers.
