Meaning: 'Autonomy' means the right or condition of self-government, particularly in making personal decisions without external interference.

Wrong options:

• certainty: 'Certainty' refers to being sure or confident about something, which does not relate to the concept of mental privacy or control over one's mind.
• harmony: 'Harmony' implies a pleasing arrangement or agreement, which is not relevant to the context of individual rights and mental privacy.

Correct answer: propose

Explanation: The verb 'propose' is appropriate here as it indicates the act of suggesting new ideas or rights, fitting grammatically and contextually with the sentence structure and the overall theme of introducing new human rights.

Meaning: 'Propose' means to put forward an idea or plan for consideration or discussion.

Wrong options:

• resoft: 'Resoft' is not a standard English word and does not fit the context of suggesting new rights.
• decide: 'Decide' implies making a choice or conclusion, which does not align with the act of suggesting new rights; it lacks the nuance of proposing ideas.
• execute: 'Execute' means to carry out or put into effect, which does not fit the context of introducing new rights.

Correct answer: already

Explanation: The adverb 'already' indicates that actions have been taken prior to the present time, fitting grammatically and contextually as it emphasizes that steps have been taken in the past to protect these rights.

• yet: 'Yet' suggests something that has not happened up to this point, which contradicts the context of actions already taken.
• too: 'Too' implies excessiveness and does not fit grammatically or contextually in this sentence.
• still: 'Still' indicates continuity or persistence, which does not accurately convey the idea that actions have been completed.

Correct answer: passed

Explanation: The verb 'passed' is the correct choice as it indicates that legislation has been officially approved, fitting both grammatically and contextually within the sentence about legal actions taken by Colorado.

Meaning: 'Passed' means to approve or enact legislation, indicating that a law has been successfully adopted.

Wrong options:

• realized: 'Realized' means to become aware of something or to make something real, which does not fit the context of legislative action.
