Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator . They want it to take the place of litmus paper. "We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other." British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world. But when the kids did some experiments in class last winter, they saw that the litmus paper didn't turn very blue with base matter. It's hard to get a clear result. Will there be a better indicator than litmus paper? The three kids decided to try and find out! How? They went to collect over 40 plants in parks, gardens and markets. Then they ground leaves, flowers and stems to get the pigments from them. The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper! "It's our first scientific journey, Huang said, "But it makes me want to try harder." Question: From the text, a red cabbage is a kind of _ . - plant - animal - paper - liquid
