Why do you think Anne’s diary has been published in 55 languages?

The diary has been published in 55 languages so people all over the world can learn about Anne. That is why the passage says it has been continuously in print.
So everyone could understand it is incorrect because it is too vague. Because Anne was Jewish but hid in Amsterdam and died in Germany is incorrect because it was published after Anne died and she did not write in all three languages. The last choice is incorrect because the passage does not give us any information about what languages Otto Frank spoke.
