Work in pairs. Student A reads text A and asks Student В questions on the information absent in the text. Student В answers the questions using text B. Then Student В asks Student A questions on the information missing in text B. Student A answers the questions taking information from text A. In this way both students get full information about D. I. Mendeleyev, write his CV and hand it to the teacher.
