You can have transit advertising that is guerilla marketing.

你可能会看到公交广告，这属于游击式营销。

So during your exam you can say, " I don't like transit advertising. I hate telemarketing, but I think that sponsorships, especially in my country, are very effective in getting people to either recognize a brand or to buy a certain brand."

所以在考试的时候你可以说" 我不喜欢公交广告。我讨厌电话销售，但是我认为赞助，尤其是在我的国家，是让人们认识一个品牌或者购买某个品牌的非常有效的方式。"
