Translation:Which Shinkansen is the fastest?
While i can see where you're coming from, you can do what I do and close your eyes and listen. The lack of Kanji is not only annoying to read, it's uneducational in the long run as we will eventually need to know these Kanji anyways. Better to have it reinforced with every question.
For example, in one of the other questions, a fellow student did not know how to read 肉. I don't blame them at all - such a simple Kanji has never/barely ever come up.
