Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Example Input: Diabetic nephropathy is the leading cause of end-stage renal disease in humans in the Western world. The recent development of Na+-glucose cotransporter 2 (SGLT2) inhibitors offers a new antidiabetic therapy via enhanced glucose excretion. Whether this strategy exerts beneficial effects on the development of type 2 diabetic nephropathy is still largely unclear. We investigated the effects of the specific SGLT2 inhibitor empagliflozin in BTBR.Cg-Lep<ob>/WiscJ (BTBR ob/ob) mice, which spontaneously develop type 2 diabetic nephropathy. In the first experiment, BTBR ob/ob mice received either a diet containing 300 ppm empagliflozin or equicaloric placebo chow for 12 wk. In the second experiment, BTBR ob/ob mice received 1 gkg body wt(-1)day(-1) ANG II to induce arterial hypertension and were separated into the same two diet groups for 6 wk. In both experiments, empagliflozin treatment enhanced glucosuria, thereby lowering blood glucose. Independently of hypertension, empagliflozin reduced albuminuria in diabetic mice. However, empagliflozin treatment affected diabetes-related glomerular hypertrophy, markers of renal inflammation, and mesangial matrix expansion only in BTBR ob/ob mice without hypertension. In summary, empagliflozin demonstrated significant antihyperglycemic effects, differentially ameliorating early features of diabetic nephropathy in BTBR ob/ob mice with and without hypertension.
Example Output: Which protein does empagliflozin inhibit?

Example Input: The tradition of birthday parties started in Europe a long time ago. It was feared that evil spirits were particularly attracted to people on their birthdays. To protect them from harm, friends and family members would come to stay with the birthday person and bring good thoughts and wishes. Giving gifts brought even more good cheer to keep away from the evil spirits. This is how birthday parties began. The following are some countries' birthday traditions: Canada---Putting butter on the nose. In Atlantic Canada, the birthday child's nose is put butter on for good luck. China---Noodles for lunch. The birthday child pays respect to his / her parents and receives a gift of money. Friends and relatives are invited to lunch and noodles are served to wish the birthday child a long life. England---Money cakes. Certain symbolic objects are mixed into the birthday cake as it is being prepared. If your piece of cake has a coin in it, you will be rich. Ireland---Birthday bump . The birthday child is lifted upside down and " bumped" on the floor for good luck. Italy---Pulling ears. The child's ears are pulled as many times as how old he / she is turning. Japan---New clothes. The birthday child wears new clothes to mark the occasion. New Zealand---Birthday claps. After the candles are hit, the happy birthday song is sung loudly and often out of tune and then the birthday person receives a clap for each year he / she has been alive and then one for good luck. The United States---Cake, candles and the birthday song. A cake is made, and candles are put on top based on how old the person is.
Example Output: According to the passage, in which country can the birthday children probably receive a gift of money?

Example Input: Something strange was unbelievable. Take Robert for example. After the terrible car accident, his whole world had been completely dark and quiet for almost ten years. The loss of sight and hearing made him try many times to put end to his life. His family especially his wife did their best to tend and comfort him. By and by he finally regained the courage to live on. On a hot summer afternoon he was taking a walk with a stick near his house when a thunderstorm started suddenly. He stood under a large tree in order not to get himself wet. Unfortunately he was struck down to the ground by a lightning. The witnesses thought him dead but he woke up some 20 minutes later lying face down in muddy water below the tree. He felt that he was trembling badly, but when he opened his eyes ,he didn't dare to believe that he saw a plough( )lying near the wall. When Mrs Edwards came running up to him, she shouted their neighbours for help. And he saw her and heard her voice for the first time in nearly ten years. The news of Robert's regaining his sight and hearing quickly spread in his area. And many doctors came to prove the truth of the news. Most of them said that he gained sight and hearing again obviously from the knock of lightning; none of them could give convincing reasons, however. The only reasonable explanation given by one doctor was that, since Edwards lost his sight and hearing as a result of sudden shock in a terrible accident, perhaps the only way for them to regain was by another sudden shock.
Example Output:
What did Edwards see first after being struck down by a lightning?
