Q. Your teacher will dictate these paragraphs to you. Write down the paragraphs with correct punctuation marks.

In 1931 Charlie Chaplin invited Albert Einstein, who was visiting Hollywood, to a private screening of his new film, City Lights. As the two men drove into town together, passersby waved and cheered. Chaplin turned to his guest and explained: ‘‘The people are applauding you because none of them understands you and applauding me because everybody understands me.’’

One of Einstein’s colleagues asked him for his telephone number one day. Einstein reached for a telephone directory and looked it up. ‘‘You don’t remember your own number?’’ the man asked, startled.

‘‘No,’’ Einstein answered. ‘‘Why should I memorise something I can so easily get from a book?’’ (In fact, Einstein claimed never to memorise anything which could be looked up in less than two minutes.)
