How are today's neighborhood stories similar and different from the old neighborhood stories?

The neighborhood stores today are different because they have different races running the stores,but they are also similar because they still have the same issue of being excluded from others because of their ethnicity.

the following key ideas correctly express the key sentence.

restate key idea: most people can learn to swim in ten short lessons.

restate key idea: the majority of water-accident victims require mouth-to-mouth breathing.

restate key idea: an empty, tightly closed gallon jug will support a tired swimmer.  

restate key idea: first aid is to prevent accidents as well as assist in rescue.

explanation: the key idea needs to have the same topic as the key sentence (drowning and safety).

i believe that's the correct answer
