Q: story: Mr. Laurence was not allowed to see Beth, and Meg felt unhappy writing letters to her mother saying nothing about Beth's illness. Jo nursed Beth night and day, but the time came when Beth did not know her and called for her mother. Jo was frightened, and Meg begged to be allowed to write the truth, but Hannah said there was no danger yet. Then a letter came saying that Mr. March was worse and could not think of coming home for a long time. How dark the days seemed. How sad and lonely. The sisters worked and waited as the shadow of death lay over the once happy home. It was then that Meg realized how rich she had been in the things which really mattered--love, peace, good health. And Jo, watching her little sister, thought about how unselfish Beth always was--living for others and trying to make home a happy place for all who came there. Amy, sad and lonely at Aunt March's house, just wanted to come home so that she could do something to help Beth. On the first day of December, the doctor came in the morning. He looked at Beth, then said quietly, 'If Mrs. March can leave her husband, I think she should come home now.' Jo threw on her coat and ran out into the snow to send a telegram. When she arrived back, Laurie came with a letter saying that Mr. March was getting better again. This was good news, but Jo's face was so unhappy that Laurie asked, 'What is it? Is Beth worse?' 'I've sent for Mother,' said Jo, beginning to cry. 'Beth doesn't know us any more.' Laurie held her hand and whispered, 'I'm here, Jo. Hold on to me. Your mother will be here soon, and then everything will be all right.', question: Who was taking care of Beth?
