The intro

(Listening Comprehension)

Hello ! It's Mr.Wong here. I've been watching a lot of Detective Conan（日本动漫《名侦探柯南》）lately. And by the way, shout outs to Poppy（人名） for letting me know about this awesome anime ! So as I was reading the subtitles, I noticed the word "concrete" evidence. "Concrete" means a very hard building material made by mixing together cement, sand, small stones and water, but it also means "based on the sure facts or existing things rather than guesses or theories". Okay ! let's say, if a statement, argument, or discussion is "concrete", it is based on actual things and particular examples, which is gonna be our word for today. Check it out !
