Read the paragraph below. Find the topic sentence:a) Learning a second language can provide a deeper understanding a foreign culture. b) Social habits that may not make sense to most outsiders might start to make more sense after a few vocabulary lessons. c) For example, I always wondered why my Dutch cousins rarely said “you’re welcome” after I said “thank you”. d) My cousin can speak English but sometimes makes mistakes. e)At first I thought he was being rude, but when I learned more about his language I realized that they don’t use “you’re welcome” the same way we do: in response to “thank you”. f) They actually say something that translates to “if you please” when they offer you something. g) This is one of the first things I learned about Dutch culture when I started to learn their language and it gave me a different perspective on the roles of the host and guest, since in Dutch the onus to be polite is on the host, and not the guest as it seems to be in English.
