"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.

Input: Consider Input: Penobscot tribal chiefs expressed a willingness to enter peace talks with Lieutenant Governor Dummer in December 1724. They were opposed in this by French authorities, who continued to encourage the conflict, but Massachusetts Lieutenant Governor Dummer announced a cessation of hostilities on 31 July 1725 following negotiations in March.:83 The terms of this preliminary agreement were negotiated by Dummer and Chiefs Loron and Wenemouet and applied only to the Penobscots at first. They were allowed to retain Jesuit priests, but the two parties were in disagreement concerning land titles and British sovereignty over the Wabanakis. The written agreement was translated into Abenaki by French Jesuit Etienne Lauverjat; Chief Loron immediately repudiated it, specifically rejecting claims of British sovereignty over him. Despite his disagreement, Loron pursued peace, sending wampum belts to other tribal leaders, although his envoys were unsuccessful in reaching Gray Lock, who continued his raiding expeditions. Peace treaties were signed in Maine on 15 December 1725 and in Nova Scotia on 15 June 1726, involving a large number of tribal chiefs. The peace was reconfirmed by all except Gray Lock at a major gathering at Falmouth in the summer of 1727; other tribal envoys claimed that they were not able to locate him. Gray Lock's activity came to an end in 1727, after which time he disappears from English records.

Output: At what event was Gray Lock discovered to be missing?


Input: Consider Input: Watanabe et al (Reports, 12 April 2013, p. 195) study the yeast SWR1/SWR-C complex responsible for depositing the histone variant H2A.Z by replacing nucleosomal H2A with H2A.Z. They report that reversal of H2A.Z replacement is mediated by SWR1 and related INO80 on an H2A.Z nucleosome carrying H3K56Q. Using multiple assays and reaction conditions, we find no evidence of such reversal of H2A.Z exchange.


Output: Which protein mediates the replacement of H2A by H2A.Z in the yeast Saccharomyces cerevisiae?
