Final answer:
In the novel 1984, the parallel to the German bombings during the Blitz is the constant surveillance and control exercised by the Party.
Step-by-step explanation:
The parallel in 1984 to the statement 'from September 1940 to May 1941 Germany repeatedly bombed British cities during the Blitz' can be seen in the constant surveillance and control exercised by the Party in the novel.
In 1984, the Party employs telescreens and Thought Police to monitor and manipulate the lives of its citizens, just as the German bombings aimed to break the will of the British people.
Similar to the Blitz, the Party's tactics in 1984 are aimed at instilling fear and maintaining control over its subjects.
