see children sitting on the bed, rocking back and forth and memorising lessons in the book kept on a pillow in front. Read each sentence to find out whether there is any error in it. The error, if any, will be in one part of the sentence. Mark the part with the error as your answer. If there is no error, mark "No Error" as your answer. (Ignore the errors of punctuation).Solution
