PROBLEM: Context: Long long ago, there was an old merchant who had three sons. "To which one shall I leave my fortune?" he wondered. "It must be to the cleverest son. But which one is the cleverest?" He called his three sons to him. "Here is some money," he told them, "you must each take one coin to buy something that will fill this room. Anyone who can do this shall have my fortune." "It is a big room," said the eldest son. "One coin will not buy very much," said the second son. But the youngest son said nothing. He stood and thought, and then he smiled, "Come, brothers," he said, "let us go to the market." The eldest son bought straw with his coin. But one coin bought only a bit of straw. Even when he had spread it as much as he could, the straw covered only a corner of the room. The second son bought sand with his coin. But one coin bought only a bit of sand. Even when he had spread it as much as he could, the sand covered only half of the floor. "What did you buy?" the eldest son angrily asked the youngest son. "You don't have any straw." "Yes, what did you buy?" the second son asked angrily. "You don't have any sand." "I bought this," said the youngest son. "A candle!" cried his brothers. "What good is a candle?" "Watch", said the youngest son. He lit the candle, and all at once the room was filled from wall to wall, from ceiling to floor. It was filled with light! "Although you are the youngest, you are indeed the cleverest of my sons," the old merchant said. And that is how, the old merchant left his fortune to his youngest son, the one who could fill a room with light. 
 Question: Who would get father's fortune?

PROBLEM: Context: Spleen tyrosine kinase (Syk) is involved in the development of the adaptive immune system and has been recognized as being important in the function of additional cell types, including platelets, phagocytes, fibroblasts, and osteoclasts, and in the generation of the inflammasome. Preclinical studies presented compelling evidence that Syk inhibition may have therapeutic value in the treatment of rheumatoid arthritis and other forms of arthritis, systemic lupus erythematosus, autoimmune cytopenias, and allergic and autoinflammatory diseases. In addition, Syk inhibition may have a place in limiting tissue injury associated with organ transplant and revascularization procedures. Clinical trials have documented exciting success in the treatment of patients with rheumatoid arthritis, autoimmune cytopenias, and allergic rhinitis. While the extent and severity of side effects appear to be limited so far, larger studies will unravel the risk involved with the clinical benefit. 
 Question: Which enzyme is inhibited by a drug fostamatinib?

SOLUTION:
spleen tyrosine kinase
