Why the other options are wrong:

• an accident on the University Bridge.: Traffic is being rerouted to the University Bridge because the Broadway Bridge is closed. The closure followed damage found during an inspection; the report does not describe an accident on the University Bridge.
• a long-term plan to replace bridges.: There is no long-term plan to replace bridges discussed in the report.
• new bus routes across the city.: New bus routes are not the topic - some bus routes are temporarily detoured because of the bridge closure.

Correct Answer: after inspectors found structural damage.

Why this is correct: The report says the closure was ordered after inspectors found damage to a support joint during a routine safety check. Structural damage found during inspection is the reason the bridge was closed.

Why the other options are wrong:

• due to seasonal river flooding.: Seasonal river flooding is not mentioned as the cause of the closure.
• because of a rush-hour collision.: The damage was found during a routine safety inspection. The report does not attribute the closure to a rush-hour collision.
• as part of planned summer construction.: The closure was unexpected, not part of planned summer construction.

Correct Answer: use alternate routes adding travel time.

Why this is correct: The report says traffic has been rerouted to the University Bridge and Circle Drive Bridge, adding up to twenty minutes to some commutes. So commuters must use alternate routes, which adds extra travel time.

Why the other options are wrong:

• demand the bridge reopen immediately.: The report does not say commuters are demanding the bridge reopen immediately.
• avoid the city centre entirely.: People are not avoiding the city centre entirely - they are using other bridges to get across the river.
• switch to walking or cycling only.: The report does not say people are switching to walking or cycling only.

Correct Answer: needs repairs but poses no immediate risk of collapse.

Why this is correct: Transportation director Mark Davidson said the damage does not pose an immediate risk of collapse, but repairs are necessary before the bridge can reopen safely. So the bridge needs fixing but is not in danger of collapsing right now.

Why the other options are wrong:

• must be completely rebuilt.: Davidson did not say the bridge must be completely rebuilt - repairs are estimated at 1.8 million dollars.
• will take all year to fix.: The work is expected to take three weeks, not all year.
• can reopen within a few days.: Three weeks is the estimated repair time, not a few days.

Correct Answer: balancing public safety with reduced disruption.

Why this is correct: The city closed the bridge for safety but is working extended hours to reopen it quickly. They have rerouted traffic, given a target reopening date, and are providing updates. This shows they are balancing public safety with keeping disruption as short as possible.

Why the other options are wrong:

• planning to close the bridge permanently.: The city is not planning to close the bridge permanently - repairs should take about three weeks.
• expecting delays to worsen all summer.: The city expects to reopen in early July, not have delays all summer.
• unconcerned about commuter frustration.: The city is sharing updates and asking for patience, showing they care about commuter frustration.
