During World War II, the British government established the Bletchley Park codebreaking center, where mathematicians and linguists worked to decipher German communications encrypted with the Enigma machine. The work remained classified for decades after the war ended. Several major contributors received public recognition only posthumously, and some technical innovations developed at Bletchley were independently rediscovered by civilian researchers years later.
Which conclusion most logically follows from the passage?
- Acheck_circle
Wartime classification practices can shape the historical record long after a conflict ends
- B
Bletchley Park's contributions were widely publicized during the war
- C
Civilian researchers had access to all wartime classified materials
- D
Enigma was a simple device that any researcher could decipher
Explanation
Decades-long classification, posthumous recognition, and rediscovery support A. B, C, D contradict the passage.
