Why the other options are wrong:

• changes to TTC subway service.: The TTC subway Line 1 was not affected - only some bus routes had detours.
• flooding damage to nearby homes.: The transcript says nearby homes did not lose drinking water and there was no flooding damage mentioned.
• a long-term plan to replace pipes.: The report is about an emergency repair, not a long-term pipe replacement plan.

Correct Answer: near Yonge Street and Eglinton Avenue.

Why this is correct: The transcript says the break happened just before 7am near Yonge Street and Eglinton Avenue. This is the exact location given in the report.

Why the other options are wrong:

• outside a North York subway station.: The break was near Yonge and Eglinton in midtown, not outside a North York subway station.
• along Highway 401 at Yonge.: Highway 401 is not mentioned in the report at all.
• near City Hall downtown.: The break happened in midtown Toronto, not near city hall downtown.

Correct Answer: its age and normal wear.

Why this is correct: Toronto Water spokesperson Liam O'Donnell said the pipe was more than 60 years old and failed due to normal wear and tear. Age and regular use caused the failure.

Why the other options are wrong:

• freezing temperatures overnight.: Freezing temperatures are not mentioned as a cause of the break.
• damage from nearby construction.: There is no mention of nearby construction causing damage to the pipe.
• heavy water use by businesses.: Heavy water use by businesses is not given as a reason for the failure.

Correct Answer: temporary detours on some bus routes.

Why this is correct: The transcript says the TTC reported temporary bus detours because of the road closures. Bus routes in the area were rerouted around the break.

Why the other options are wrong:

• streetcars replacing subway service.: Streetcars replacing subway service is not mentioned in the report.
• no changes to any TTC service.: There were changes - bus routes had temporary detours, so service was affected.
• a shutdown of all subway lines.: Subway Line 1 was not affected, so not all subway lines were shut down.

Correct Answer: treating the situation as urgent.

Why this is correct: Emergency repair teams arrived within an hour, crews closed lanes quickly, and repairs are continuing through the afternoon. The city is treating this as an urgent situation that needs fast action.

Why the other options are wrong:

• planning to delay repairs.: Repairs are happening right away, not being delayed.
• unsure about the cause.: The spokesperson identified the cause as wear and tear, so they are not unsure.
• expecting disruptions for several days.: Repairs are expected to continue through the afternoon, with at least one lane reopening by early evening. The report does not forecast several days of disruption.
