"<span>In early 1927 the Guomindang-CCP rivalry led to a split in the revolutionary ranks. The CCP and the left wing of the Guomindang had decided to move the seat of the Nationalist government from Guangzhou to Wuhan. But Chiang, whose Northern Expedition was proving successful, set his forces to destroying the Shanghai CCP apparatus and established an anti-Communist government at Nanjing in April 1927. There now were three capitals in China: the internationally recognized warlord regime in Beijing; the Communist and left-wing Guomindang regime at Wuhan; and the right-wing civilian-military regime at Nanjing, which would remain the Nationalist capital for the next decade."</span>

Answer: D. Tacit-knowledge
Explanation: The question does not indicate whether the participants were able to indicate in which direction the arrow was pointing, but in each case, if they were able to do so, they could succeed with the help of tacit knowledge.
Tacit knowledge is knowledge that cannot be written down or transmitted to someone else in the form of a skill, it means to teach someone else to know tacit knowledge, it is impossible. Tacit knowledge is gained through experience in a business and cannot be explained to someone else. It can be said that this knowledge is experienced, so it is tacitly learned and acquired, so it cannot be explained. For example, cycling is learned by getting on the bike and when you start to ride you will fall several times. The moment you started riding and you didn't fall, you learned to ride a bike, although at that moment you can't explain how.
