Answer:
A.) army
Explanation:
Columbia, as all countries in the world, has its own government which is responsible for controlling the country. If the government comes into a situation where it is not able to control the country, or it has been overthrown so there's no government in place, second in charge is the military. The military is the one that will have the obligation of keeping things under control in Colombia in a non-government situation, as that is what the legislative says. In practice that will be incredibly hard though, as the drug cartels in Colombia are very powerful, so there's every chance that they will be able to take over whole regions of the country, or even all of the country in a scenario like that.
Answer: submarine attacks
Context/detail:
Public outrage in the US against the Germans swept the nation following the sinking of the British ocean liner, Lusitania. When a German U-boat (submarine) sank the Lusitania in May, 1915, over 1,000 persons were killed, including more than 100 Americans. The passenger liner was targeted by the Germans because they suspected weapons were being shipped to Britain in the cargo hold of the ship.
Germany managed to stave off American entry into the war at the time by pledging to stop submarine attacks. But a couple years later they resumed such attacks, and there was also an intercepted telegram that showed Germany was trying to secure Mexico as an ally against the United States. In 1917, the US declared war on Germany in response.
