b. A person can refuse to testify against himself or herself.
Explanation:
The Fifth Amendment states, among other things, a series of rights that a defendant has in criminal procedures, one of them is their right to protect against self-discrimination, that is to say, their right to refuse to testify against himself or herself.
The other rights concerning criminal procedures that the Amendment protects are the right to a grand jury, to be protected from "double jeopardy" and to due process of law when a person is "deprived of life, liberty, or property."
The Fifth Amendment states that: No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.
In addition to this separation of powers, the framers built a system of checks and balances designed to guard against tyranny by ensuring that no branch would grab too much power.
A new study shows that Native Americans' land use nearly a century ago produced a widespread impact on the eastern North American landscape and floodplain development several hundred years prior to the arrival of major European settlements.
The correct answers are "mediocre" and "greedy". Dr Faustus sell his soul to the devil in order to have absolute power and dominate the whole world. However this early over ambitious behaviour, results in mediocrity as Faustus does not know what to do with so much power once he has it.
