Direction : Read the passage given below and answer the question that follow by selecting the most appropriate option. 1. Karuna Verma is bewildered. "I don't know how she did it," she says about her mother, Renu Chopra. Karuna's childhood memories are of her father leaving late for office so that, by      then, her mother would be back from work. Of her parents working in sync to make sure the kids were well taken care of. Of her mother handling kitchen and classroom with ease. 2.When her own daughter was born, Karuna too wanted to do the balancing act. But it did not turn out to be as easy as it seemed. For starters, her parent's era was different from hers. As she was living with her husband in Andheri, Mumbai, away from their families, resuming work would have meant leaving her daughter with a maid while she was away. Her daughter's formative years would be spent with an outsider, a thought that did not appeal  to Karuna. She quit her teaching job in a school. 3.For a woman who was encouraged to be independent, throughout her life, the decision to quit and stay at home was a difficult one. Ironically it was her mother who urged her to quit the job and become a full-time mother. For Karuna, being a housewife is one of the tougher jobs she has had. "I have no time for myself," says Karuna. "I make sure all my personal work is done when Avni is asleep. Earlier I had a set routine. My husband and I used to wake up at 6 a.m. I would re-heat the food the maid had cooked the day before and pack it for lunch. Then we used to head off to work, and at night, we would go out. I had a lot of time to myself and for my husband then," says Karuna. 4.The routine is quite different now. Karuna has taken to cooking. She wakes up quite early and makes sure all her work is done before the baby is up. The rest of the day flies by, pandering to two- year-old Avni's needs.
