The correct answer is B. There was a large gap between the rich and the poor in Cuba.
Explanation
After Cuba's independence, labor issues internally in the country did not change radically, sugar cane plantations continued to be places where workers were exploited and landowners took advantage of this situation by increasing their wealth more. Likewise, in the cities, the foreign industry took advantage of Cuban workers by paying them miserable wages while they benefited widely from the sale of manufactured products, which created a wide gap between the rich and the poor. This caused great dissatisfaction in the working population of Cuba, which led to the creation of unions to pressure the government to change these situations. Faced with this situation, the government did not make major changes, on the contrary, it began to repress unionists, so the population decided to take up arms and form guerrillas to radically change the entire island. According to the above, the statement best describes a primary cause of the Cuban Revolution is B. There was a large gap between the rich and the poor in Cuba.
