Are this questions right? I do some work about Russian writer Teffi, so is everything alright with this sentences? 1. In what article did Teffi let the mask of light humorist to slip? 2. What is Teffi's secretive and self-protective expressed in? 3. How old was Teffy when she died? 4. Why do you think the collection has several translators? 5. Why don't translators talk about the difficulties of translation in the introductory articles? 6. Is it possible “to be able to “speak, think and act” on behalf of a French person” if you are Russian and why? Thank you!
