The following text is for questions 40 to 42.   "Why do you look unhappy?" asked Mr. Anto.     "I didn't have a great harvest this season," explained Mr. Toni.     "Don't worry. I have the solution," said Mr. Anto.     "What is it?" asked Mr. Anto.     "Here it is. Nutrition for soil and your plants," said Mr. Toni while showing Mr. Anto a bottle of nutrition.     "What is the function of such nutrition?" asked Mr. Anto.     "It will make the soil more fertile. You only need to spread it onto the land and the plants will grow very well," explained Mr. Toni.     "Are you sure that it will work?" asked Mr. Anto, hesitantly.     "Yes. I have proved it. I have a great harvest now," said Mr. Toni.     "How can I get the nutrition? Is it available in stores?" asked Mr. Anto.     "So far, it is only sold online. I can buy it for you if you are interested," told Mr. Toni.     "Thanks. I hope it works and I get a great harvest next year," said Mr. Anto, hopefully.     "I hope so," replied Mr. Toni.
