Problem: Separation of powers under the United States Constitution:

Strict separation of powers did not operate in The United Kingdom, the political structure of which served in most instances[citation needed] as a model for the government created by the U.S. Constitution.[citation needed] Under the UK Westminster system, based on parliamentary sovereignty and responsible government, Parliament (consisting of the Sovereign (King-in-Parliament), House of Lords and House of Commons) was the supreme lawmaking authority. The executive branch acted in the name of the King ("His Majesty's Government"), as did the judiciary. The King's Ministers were in most cases members of one of the two Houses of Parliament, and the Government needed to sustain the support of a majority in the House of Commons. One minister, the Lord Chancellor, was at the same time the sole judge in the Court of Chancery and the presiding officer in the House of Lords. Therefore, it may be seen that the three branches of British government often violated the strict principle of separation of powers, even though there were many occasions when the different branches of the government disagreed with each other. Some U.S. states did not observe a strict separation of powers in the 18th century. In New Jersey, the Governor also functioned as a member of the state's highest court and as the presiding officer of one house of the New Jersey Legislature. The President of Delaware was a member of the Court of Appeals; the presiding officers of the two houses of the state legislature also served in the executive department as Vice Presidents. In both Delaware and Pennsylvania, members of the executive council served at the same time as judges. On the other hand, many southern states explicitly required separation of powers. Maryland, Virginia, North Carolina and Georgia all kept the branches of government "separate and distinct."

What country's government served as a model for the United States Government?

A: United Kingdom


Problem: Predation:

Predatory animals often use their usual methods of attacking prey to inflict or to threaten grievous injury to their own predators. The electric eel uses the same electric current to kill prey and to defend itself against animals (anacondas, caimans, egrets, jaguars, mountain lions, giant otters, humans, dogs, and cats) that ordinarily prey upon fish similar to an electric eel in size; the electric eel thus remains an apex predator in a predator-rich environment. A predator small enough to be prey for others, the domestic cat uses its formidable teeth and claws as weapons against animals that might confuse a cat with easier prey. Many non-predatory prey animals, such as a zebra, can give a strong kick that can maim or kill, while others charge with tusks or horns.

What defense does a zebra have against predators?

A: strong kick that can maim or kill
