Why the other options are wrong:

• an increase in overnight police staffing.: Police will still respond to high-risk incidents, but the story is about noise regulations, not police staffing.
• a campaign against short-term rentals.: Short-term rentals are mentioned as a source of complaints, but this is not a campaign against them.
• changes to construction safety standards.: Construction hours are affected, but the main story is about broader noise regulations.

Correct Answer: on the first of July.

Why this is correct: The report says the new noise by-laws are set to take effect starting July 1. This is stated clearly near the beginning of the report.

Why the other options are wrong:

• after the fall monitoring period.: The fall monitoring period comes after the rules take effect, not before.
• at the start of next year.: The formal review is in January, but the rules start on July 1.
• immediately after the council vote.: The rules do not take effect immediately after the vote - they start July 1.

Correct Answer: lowered by five decibels.

Why this is correct: The report says allowable noise levels will drop from 55 decibels to 50 decibels between 10 p.m. and 7 a.m. That is a reduction of five decibels.

Why the other options are wrong:

• kept the same as before.: The limits are changing - they are not staying the same.
• applied only on weekends.: The overnight limits apply every night, not only on weekends.
• increased to allow more events.: The limits are being lowered, not increased to allow more noise.

Correct Answer: target repeated disturbances, not one-time events.

Why this is correct: Maria Chen said the goal is not to penalise occasional gatherings, but to address repeat disturbances that affect entire blocks. The rules focus on ongoing problems, not one-time events.

Why the other options are wrong:

• follow a request from the police department.: She did not say the by-laws were a police department request.
• eliminate all late-night gatherings.: She specifically said the goal is not to eliminate all gatherings.
• primarily raise revenue for the city.: Raising revenue is not mentioned as the purpose of the by-laws.

Correct Answer: handled through non-emergency city services.

Why this is correct: The report says routine noise complaints will be handled through the city's 311 service, which is a non-emergency city service. Police will only respond to high-risk incidents.

Why the other options are wrong:

• handled mainly by increased police patrols.: Police patrols will handle only high-risk cases, not most routine complaints.
• delayed until enforcement begins next year.: The rules take effect July 1, so enforcement is not delayed until next year.
• limited to construction-related noise issues.: The 311 service handles all types of routine noise complaints, not just construction-related ones.
