Why the other options are wrong:

• changes to environmental safety laws.: The report does not discuss changes to environmental safety laws.
• a new playground being built.: This is not about a new playground being built - it is about an existing one being cleaned and reopened.
• a public meeting about park funding.: There is no public meeting about park funding discussed in the report.

Correct Answer: soil tests found high lead levels.

Why this is correct: The report says the play area was closed in March when routine testing found elevated levels of lead in the soil near the swings and sandbox. High lead levels in soil tests caused the closure.

Why the other options are wrong:

• children were injured there.: The report says no injuries or illnesses linked to the site were reported. The playground closed after routine tests found elevated lead levels in the soil.
• residents complained about noise.: Noise complaints are not mentioned as a reason for closing the playground.
• equipment damaged the play structures.: Equipment did not damage the play structures - the problem was soil contamination.

Correct Answer: just under three weeks.

Why this is correct: The report says the remediation work took just under three weeks to complete. Crews removed contaminated soil, replaced it with clean fill, and reinstalled the equipment in that time.

Why the other options are wrong:

• about three months.: Three months is much longer than what the report states.
• less than one week.: Less than one week is too short - the report says just under three weeks.
• nearly a full year.: Nearly a full year is far too long - the work was done quickly.

Correct Answer: the borough mayor.

Why this is correct: Borough mayor Francois Limoges said the closure was a precautionary measure. He noted there was never an immediate danger, but they acted quickly to protect children and reassure families. He is the one who used the word precautionary.

Why the other options are wrong:

• a parks maintenance worker.: A parks maintenance worker did not make this statement.
• a provincial health inspector.: A provincial health inspector is not mentioned in the report.
• a local parent group.: A local parent group did not make this comment - the borough mayor did.

Correct Answer: it takes preventive action to reduce risk.

Why this is correct: The city acted quickly when lead was found, completed cleanup in under three weeks, and plans additional soil testing across the borough later this summer. This shows they take preventive action to reduce risk rather than waiting for problems to get worse.

Why the other options are wrong:

• it reacts only after complaints.: The city found the issue through routine testing, not after complaints - they were already checking proactively.
• it will close playgrounds permanently.: The playground was reopened after cleanup, not closed permanently.
• older playgrounds are unsafe.: The report does not say all older playgrounds are unsafe - it says the city is doing broader inspections.
