There were episodes of widespread famines, and also of deadly epidemics. Soil exhaustion, overpopulation, wars, diseases and climate change cause hundreds of famines in medieval Europe.<span> Around 1300, centuries of European prosperity and growth came to a halt. Famines such as </span>Great Famine of 1315–1317<span> slowly weakened the populace. Few people died of starvation because the weakest had already succumbed to a routine disease they otherwise would have survived. A plague like the </span>Black Death<span> killed its victims in one locality in a matter of days or even hours, reducing the population of some areas by half as many survivors fled.</span>
In an effort to stabilize the Cuban economic and social unrest, Castro created a one-party government to exercise dictatorial control over all aspects of Cuba's economic, political and cultural life. Every political dissent were suppressed ruthlessly. At the same time, he expanded the country's social services, extending them to all classes of society on an equal basis. This made educational and health services available to Cubans free of charge, and every citizen was guaranteed employment.

So the only unique answer in the set -- which was the message from Civil Defense -- was that "duck and cover" was a helpful strategy in the event of a nuclear attack. Truthfully, it would not have been.
