Problem: Given the question: Given the following context:  Author Robert Rodriguez writes that while Lennon, Harrison and Starr embraced the creative freedom afforded by McCartney's band-within-a-band idea, they "went along with the concept with varying degrees of enthusiasm". According to Barry Miles, Lennon resented McCartney's direction of the band as well as how, aside from "Strawberry Fields Forever", he himself was now supplying "songs to order" rather than "writing from the heart" as he had on Revolver. Everett describes Starr as having been "largely bored" during the sessions, with the drummer later lamenting: "The biggest memory I have of Sgt. Pepper ... is I learned to play chess". Speaking in 2000, Harrison said he had little interest in McCartney's concept of a fictitious group and that, after his experiences in India, "my heart was still out there … I was losing interest in being 'fab' at that point." Harrison added that, having enjoyed recording Rubber Soul and Revolver, he disliked how the group's approach on Sgt. Pepper became "an assembly process" whereby, "A lot of the time it ended up with just Paul playing the piano and Ringo keeping the tempo, and we weren't allowed to play as a band as much."After finishing Sgt. Pepper, the Beatles took an acetate disc of the album to the American singer Cass Elliot's flat off King's Road in Chelsea, where at six in the morning they played it at full volume with speakers set in open window frames. The group's friend and former press agent, Derek Taylor, remembered that residents of the neighbourhood opened their windows and listened without complaint to what they understood to be unreleased Beatles music.  answer the following question:  What is the name of the person whose biggest memory of Sgt. Pepper is that "I learned to play chess"?

Starr


Problem: Given the question: Given the following context:  When the Gold Rush began, the California goldfields were peculiarly lawless places. When gold was discovered at Sutter's Mill, California was still technically part of Mexico, under American military occupation as the result of the Mexican–American War. With the signing of the treaty ending the war on February 2, 1848, California became a possession of the United States, but it was not a formal "territory" and did not become a state until September 9, 1850. California existed in the unusual condition of a region under military control. There was no civil legislature, executive or judicial body for the entire region. Local residents operated under a confusing and changing mixture of Mexican rules, American principles, and personal dictates. Lax enforcement of federal laws, such as the Fugitive Slave Act of 1850, encouraged the arrival of free blacks and escaped slaves.While the treaty ending the Mexican–American War obliged the United States to honor Mexican land grants, almost all the goldfields were outside those grants. Instead, the goldfields were primarily on "public land", meaning land formally owned by the United States government. However, there were no legal rules yet in place, and no practical enforcement mechanisms.The benefit to the forty-niners was that the gold was simply "free for the taking" at first. In the goldfields at the beginning, there was no private property, no licensing fees, and no taxes. The miners informally adapted Mexican mining law that had existed in California. For example, the rules attempted to balance the rights of early arrivers at a site with later arrivers; a "claim" could be "staked" by a prospector, but that claim was valid only as long as it was being actively worked.Miners worked at a claim only long enough to determine its potential. If a claim was deemed as low-value—as most were—miners would abandon the site in search for a better one. In the case where a claim was abandoned or not worked upon, other miners would "claim-jump" the land. "Claim-jumping" meant that a...  answer the following question:  What were the mining rules that established that a claim was valid only as long as it was being actively worked?

The answer is:
Mexican mining law
