Final answer:
The 'Four Olds' targeted in the Cultural Revolution were old customs, old culture, old habits, and old ideas. Without the options for the one 'O' not included, it is clear that these were the pillars of traditional Chinese society that Mao sought to eradicate.
Step-by-step explanation:
The Cultural Revolution targeted anyone embodying the 'Four Olds': old customs, old culture, old habits, and old ideas. The correct answer to the question about which one is NOT one of the 'Four Olds' would depend on the options provided, but clearly, these four categories were meant to represent anything that Mao Zedong and the Red Guards considered traditional and counter-revolutionary. Mao relied on the Red Guards, largely made up of the younger generation, to purge these elements and reinforce the tenets of the Communist Party.
