The city council’s proposal need to be approve before the park renovation can begin.

Correct Answer: needs to be approved

Detailed Explanation:
To determine the correct phrasing for the underlined part of the sentence, we need to analyze two key grammatical rules: Subject-Verb Agreement and Passive Voice Infinitive Structure.

1. Subject-Verb Agreement:
The subject of the clause is "The city council’s proposal", where the head noun is "proposal". Since "proposal" is a singular noun, it requires a singular verb form in the present tense.
- Plural/Base verb form: need
- Singular verb form: needs
Therefore, the verb must be needs.

2. Passive Voice Infinitive Structure:
The subject (the proposal) is receiving the action of approval rather than performing it. When a subject receives an action, the sentence requires the passive voice.
The standard pattern for an infinitive in the passive voice after a verb like "needs" is:
to be + past participle of the verb
- Base verb: approve
- Past participle form: approved
Thus, the correct passive infinitive is to be approved.

Conclusion:
Combining the singular verb form with the passive infinitive yields "needs to be approved".
The fully corrected sentence reads: "The city council’s proposal needs to be approved before the park renovation can begin."
