thank you!
i'ts this silly homework where we are supposed to write our own examples after this pattern:
大阪で買い物をしたり、韓国料理をたべたりします。
In Osaka, I will do such things as shopping and eating Korean dishes.
so, it's to mention things or activities as examples, not as the only things one will do, with this: activity A たり activity B たりする pattern.
And you answered my question considering the particle..
ありがとございます。
