Example Input: It had been some time since Jack had seen the old man.Over the phone ,his mother told him,"Mr.Belser died last night ,The funeral is Wednesday."Memories flashed through his mind like an old newsreel as he sat quietly remembering his childhood days. When Jack was very young ,his father died.Mr Belser,who lived in the same neighborhood with them,spent as much time as he could to make sure Jack had a man's influence in his life.He spent a lot of time teachimg Jack he thought what was important in his following life.If Mr.Belser hadn' taught him how to weave,he wouldn't be in this business now.So he promised his mother he would attend Mr.Belser's funeral. "You'd better not drive your car.It's a long way."his mother warned him. Busy as he was,he kept his word.Though tired from the earliest flight,Jack tried his best to help.Mr.Belser's funeral was small because he had no children of his own and most of his s had passed away. The night before he had to return home,Jack and his mother stopped by to see the old house Mr.Belser once lived.Now it belonged to him.He bought the house from one of his s. The house was exactly as he remembered.Every step held memories.Every picture,every piece of furniture... Jadk stopped suddenly. The box on his desk was gone!He once asked the old man what was inside.He just smiled and said it was the most valuable thing to him,though it almost cost nothing to others.He figured that someone from the Belser family had taken it ."I will never know what was so valuable to him."Jack thought disappotntedly. Three days later returning home from work,Jack discovered a small package in his mailbox. The handwriting was difficult to read,but the return address caught his attention."Mr.Harold Belser"it read. Jack couldn't wait to open it .Inside lay the familiar small box.His heart racing,Jack unlocked the box.Inside he found a gold pocket watch with these words engraved:"Jack,Thanks for your time!Harold Belser." "The thing he valued most was my time."Jack held the watch before his chest,tears filling his eyes.
Example Output: What did Mr.Belser teach Jack when he aws young?

Example Input: Chronic myeloid leukemia (CML) is a progressive and often fatal myeloproliferative neoplasm. The hallmark of CML is an acquired chromosomal translocation known as the Philadelphia chromosome (Ph), which results in the synthesis of the breakpoint cluster region-Abelson murine leukemia (BCR-ABL) fusion oncoprotein, a constitutively active tyrosine kinase. The introduction of imatinib, a tyrosine kinase inhibitor (TKI) that is specific for BCR-ABL, was a major breakthrough in CML therapy. Although most patients respond to first-line imatinib therapy, some experience loss of response (resistance) or require treatment discontinuation because of toxicity (intolerance). For patients with CML, failure on standard-dose imatinib therapy (400 mg daily), imatinib dose escalation (600-800 mg daily) is a second-line option. However, high-dose imatinib is not an appropriate approach for patients who experience drug toxicity, and there remain questions over the durability of responses achieved with this strategy. Alternative second-line options include the TKIs dasatinib and nilotinib. A substantial amount of long-term data for these agents is available. Although both are potent and specific BCR-ABL TKIs, dasatinib and nilotinib exhibit unique pharmacologic profiles and response patterns relative to different patient characteristics, such as disease stage and BCR-ABL mutation status. To optimize therapeutic benefit, clinicians should select treatment based on each patient's historic response, adverse-event tolerance, and risk factors.
Example Output: What tyrosine kinase, involved in a Philadelphia- chromosome positive chronic myelogenous leukemia, is the target of Imatinib (Gleevec)?
