Question

in all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the state and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the assistance of counsel for his defense. this amendment protects the right to a public trial. it makes it illegal for a secret police force to arrest someone without telling them the reason. the police cannot whisk an american citizen off, throw them in an underground cell and have a \trial\ for them that they cannot attend. many countries have held these types of trials, and some countries still engage in these practices today. what is the purpose of the underlined sentence in the passage above? a it provides an example of an action that is illegal under the sixth amendment. b it provides an example of an action that is protected by the sixth amendment. c it provides a description of a fair, public trial. d it suggests the sixth amendment is no longer necessary.

Explanation:

文中提到该修正案（第六修正案）保护公开审判的权利，使秘密警察不告知原因就逮捕人等行为违法。划线句子描述的“警察不能秘密带走美国公民并进行其无法参加的‘审判’”正是第六修正案下违法行动的例子。

Answer:

A. It provides an example of an action that is illegal under the Sixth Amendment.
