In order to revoke parole, there must be a determination of probable cause that the parolee violated the conditions of release established by the parole board and a subsequent finding that the violation, in fact, occurred.
a. true.
b. false.

True.

Explanation:

The given statement is true.

The term parole is a French term meaning spoken words and also promise. This term is generally used to describe the early release of a convict. Parole or a release to a prisoner is given to those who agree to withstand by certain conditions. This term became popular during the Middle Ages and used when the prisoners were given freedom from prison in return for their words to the authority. Therefore, when a parolee violated any condition or fail to stand on his/her words, he/she was put in prison again and this administrative act came to be known as the Parole revocation. In this way, the given statement is true.

(The same description applies to a PNP transistor with reversed directions of current flow and applied voltage.) This applied voltage causes the lower P-N junction to become forward biased, allowing a flow of electrons from the emitter into the base.
