Why the other options are wrong:

• replace all existing bus routes.: Bus replacement is not proposed.
• carry freight between warehouses.: Freight is not the stated purpose.
• close the downtown terminal.: Downtown is a destination, not a closure.

Correct Answer: comment on the proposed design.

Why this is correct: Design consultation precedes construction.

Why the other options are wrong:

• choose the ferry operator.: No operator selection is mentioned.
• vote on the total budget.: The council already budgeted the funds.
• approve safety inspections.: Vessel inspections are a later condition of service.

Correct Answer: depart every fifteen minutes.

Why this is correct: The frequency is explicitly qualified by time.

Why the other options are wrong:

• depart every half hour.: Half-hour departures apply at other times.
• operate only after sunset.: The service is not restricted to night.
• follow the bridge traffic schedule.: No bridge-based timetable is given.

Correct Answer: provide a shuttle from an existing parking area.

Why this is correct: The shuttle is the stated response.

Why the other options are wrong:

• ban pedestrians from the terminal.: Pedestrian exclusion is not proposed.
• widen every residential street.: Street widening is not proposed.
• build a large car park beside the dock.: A large adjacent car park is explicitly rejected.

Correct Answer: decide whether to adjust departure frequency.

Why this is correct: The review informs later frequency changes.

Why the other options are wrong:

• change the bridge toll.: No toll decision is mentioned.
• select the terminal design.: Design consultation occurs before construction.
• delay all safety inspections.: Inspections precede opening, not this review.
