Strengthen: Most of the new residents will both live and work in an outlying neighborhood to the north of the city.
Weaken: Since Buryville has limited public transportation outside of the city center, workers who drive from outlying neighborhoods to the city center have no practical alternative to driving available.

Heavy traffic on Buryville’s freeways often results in much longer than expected commute times between outlying neighborhoods and the city center. Home construction in outlying neighborhoods is expected to continue to increase steadily and the total population of Buryville is projected to increase by 25% over the next 15 years. The Buryville Regional Mobility Authority plans to increase freeway capacity by only 10% over this same period. Authority officials predict that this increase will be sufficient to ensure that commute times will not increase.
Select Strengthen for the statement that would, if true, provide the strongest grounds for supporting the officials’ prediction. Select Weaken for the statement that would, if true, cast the most doubt on that prediction. Make only two selections, one in each column.

I don't understand why option B is a strengthener. Could you please explain the reasoning behind it?

1. The question asks us to find which of the statements strengthen or weaken the officials' prediction.
2. Authority officials are also planning a 5% increase in capacity for streets in the city center. We're interested in the connection between the outlying neighborhoods and city center, not just the city center. So, this statement does neither.
3. Most of the new residents will both live and work in an outlying neighborhood to the north of the city. This would mean that the new residents won't need to commute as much as normal, which would decrease the need to increase freeway capacity. So, this statement supports the officials' prediction.
4. Since Buryville has limited public transportation outside of the city center, workers who drive from outlying neighborhoods to the city center have no practical alternative to driving available. This would mean that the need for driving to and back from the city center increases, which means the need for a higher-capacity freeway increases. So, this statement weakens the officials' prediction.
5. The projected increase in freeway utilization is expected to occur gradually over time. After 15 years, the result will still be the same. So, this statement does neither.
6. The Authority expects to be able to complete the necessary construction without significant disruption to existing traffic patterns or commute times. We're not interested in how the construction will go but rather it's effect. So, this statement does neither.
7. The Authority believes that it will be able to increase freeway capacity without raising the local tax rate. The tax rate is irrelevant to the question. So, this statement does neither.
