user: Given this reference text about the Grateful Dead, tell me who their keyboard players were over the years.

assistant: <think>
The Grateful Dead was founded in the San Francisco Bay Area amid the rise of the counterculture of the 1960s. The founding members were Jerry Garcia (lead guitar, vocals), Bob Weir (rhythm guitar, vocals), Ron "Pigpen" McKernan (keyboards, harmonica, vocals), Phil Lesh (bass, vocals), and Bill Kreutzmann (drums). Members of the Grateful Dead, originally known as the Warlocks, had played together in various Bay Area ensembles, including the traditional jug band Mother McCree's Uptown Jug Champions. Lesh was the last member to join the Warlocks before they changed their name to the Grateful Dead; replacing Dana Morgan Jr., who had played bass for a few gigs. Drummer Mickey Hart and non-performing lyricist Robert Hunter joined in 1967. With the exception of McKernan, who died in 1973, and Hart, who took time off from 1971 to 1974, the core of the band stayed together for its entire 30-year history. The other official members of the band are Tom Constanten (keyboards; 1968–1970), John Perry Barlow (non-performing lyricist; 1971–1995), Keith Godchaux (keyboards, occasional vocals; 1971–1979), Donna Godchaux (vocals; 1972–1979), Brent Mydland (keyboards, vocals; 1979–1990), and Vince Welnick (keyboards, vocals; 1990–1995). Bruce Hornsby (accordion, piano, vocals) was a touring member from 1990 to 1992, as well as a guest with the band on occasion before and after the tours.</think>

user: What was the twist in this short story?

assistant: <think>
Matilda is woken up by the wind; she looks out the window; her neighbour, Marie, is fetching flowers from the garden and then Matilda’s mother is called for the telephone by Bogey, Matilda’s brother. Matilda is off to Mr Bullen's for her music lesson. Her mom does not want her to go due to the strong wind, but she goes anyway. After the lesson, she goes for a walk with her brother to the esplanade. Here, the story changes from present to past narrative as Mansfield shows that the music lesson, the walk etc. all occurred in Matilda's past, and she and her brother are actually sailing away on board a ship several years down the line, that all that went before were memories.</think>

user: Quel a été l'impact de la révolution française ?

assistant: <think>
La Révolution française est une période de bouleversements sociaux et politiques de grande envergure en France, dans ses colonies et en Europe à la fin du xviiie siècle. La période habituellement comprise s'étend entre l'ouverture des États généraux, le 5 mai 1789, et au plus tard le coup d'État de Napoléon Bonaparte le 9 novembre 1799 (18 brumaire de l'an VIII). Cette période de l'histoire de France a mis fin à l'Ancien Régime en remplaçant la monarchie absolue par une suite de régimes plus ou moins définis, dont la Première République un peu plus de trois ans après la prise de la Bastille.

La Révolution française a légué de toutes nouvelles formes politiques, notamment au travers de la Déclaration des droits de l'homme et du citoyen de 1789 qui proclame l'égalité des citoyens devant la loi, les libertés fondamentales, et la souveraineté de la Nation, et se constituant autour d'un État. « Mythe national », ses valeurs et les institutions de la Révolution dominent encore aujourd'hui la vie politique française. La Révolution a entraîné la suppression de la société d'ordres (féodalité, privilèges…), une plus grande division de la propriété foncière, la limitation de l'exercice du pouvoir politique, le rééquilibrage des relations entre l'Église et l'État et la redéfinition des structures familiales.

Elle fut marquée par des périodes de grande violence, notamment pendant la Terreur, dans le cadre de la tentative de contre-révolution de la guerre de Vendée, au cours de laquelle plusieurs centaines de milliers de personnes trouvèrent la mort, lors des insurrections fédéralistes ou dans le cadre de luttes entre factions révolutionnaires rivales, qui ont abouti à la mort successive des principales figures révolutionnaires.</think>
la révolution française a eu plusieurs impacts, sociaux et politiques. On doit à la révolution française la déclaration des droits de l'homme et du citoyen, ainsi que l'égalité des chances pour accéder au pouvoir politique, la séparation de l' église et l'état et une meilleure posture pour les femmes au sein de la société
