Input: Consider Input: Article: When people who are nature lovers worldwide wish all humans to realize the importance of their natural surroundings, many Australians are turning caring for the environment into a way of life. Julie, an Australian housewife in Brisbane is one such example. Even though autumn is approaching Australia's Brisbane in April, one can still watch colorful blooming flowers in Julie's little garden, as she tells that in her community,"Each of us has a beautiful yard. The whole community, from children to elderly people, takes care of the environment as if they are taking care of their own garden." "Gardening is the most popular club in our community," she says. "A lot of retired people don't just regularly organize gardening lectures, but also personally visit families in the community to provide gardening training. So you can see that flowers continue to blossom in our gardens throughout the year." Talking about her people's sense of caring for the environment, Julie says when people in the community take along their dog, they always carry a garbage bag to deal with the dog's waste. "In our community, you will never experience the embarrassment of stepping on the dirty waste while you are walking on the grass," says Julie with a smile. "Taking care of the dog's waste can also help to develop children's sense of responsibility!" As to protecting water resources, the Australian government has made strict rules for families. Julie says, "We certainly would not use tap water to water the flowers!" She says almost every family in her community has a huge tank used to store rainwater, which is later used as the resource of all outdoor water use, including car washing and watering the garden. This year, they also asked people to connect the water tank with their toilets.

Input: Consider Input: Article: Most painters discover a style of painting that suits them and stick to that, especially if people admire their pictures. But Picasso, the great Spanish painter, was like a man who had not yet found his own particular style of painting. He kept on struggling to find the perfect expression till his death in 1973. Some of Picasso's paintings are rich, soft color1ed and beautiful. Others are ugly and cruel and strange. But such paintings allow us to imagine things for ourselves. They force us to say to ourselves, "What does he see that makes him paint like that?" And we begin to look beneath the surface of the things we see. Picasso painted thousands of pictures in different styles. Sometimes he painted the natural look of things. Sometimes he seemed to break them apart and throw the pieces in our faces. He showed us what the mind knows as well as what the eye sees. At the age of 90 he remained as curious about the world as he had been when he was young. That's why people have called him "the youngest painter in the world..
Question: What does the passage mainly tell us?
Options: (A) Picasso didn't find his own style. (B) People can't understand Picasso. (C) Picasso's style of painting. (D) Famous paintings of Picasso.
