Kayla: Many people are reluctant to shop in our neighborhood because street parking is scarce. The city plans to address this by adding parking meters with time limits that ensure that parking spaces are generally available. But this plan will surely backfire-shoppers dislike paying at parking meters, so most will probably drive to other neighborhoods to shop at malls with free parking.

Which of the following, if true, would be the most logically effective rebuttal a proponent of the city's plan could make to Kayla's objection?

【选项】The city could post signs with street parking time limits to ensure that parking spaces become available without forcing shoppers to pay at meters.
