This LL Study Guide pulls together a quietly wild mix of topics: the NFL’s first regular-season game in Brazil, a wrap-around marching tuba, a modernist Irish poem that inspired the best‑known African novel, the geography and law of tequila, million‑dollar unsolved math problems, and a cartoon pig reshaping kids’ accents. The Eagles–Packers opener in São Paulo marked the league’s first regular‑season game in South America, expanding a global push that had already taken games to London and Germany.(packers.com) At the other end of the cultural spectrum, Peppa Pig’s four‑year‑old heroine and her love of “jumping in muddy puddles” have become so ubiquitous that lockdown binge‑watching reportedly nudged some American preschoolers toward British pronunciations like “mummy” and “holiday.”(storymuseum.org.uk)

Along the way you’ll see how John Philip Sousa’s sousaphone reshaped band music, why Chinua Achebe titled Things Fall Apart after a line from Yeats’s “The Second Coming,” how Jalisco and the town of Tequila anchor a tightly regulated denomination of origin for Mexico’s signature spirit, and why the Clay Mathematics Institute put a US$1 million bounty on seven famous unsolved problems, including Yang–Mills, Navier–Stokes, Birch and Swinnerton‑Dyer, and the Hodge conjecture.(en.wikipedia.org) Use these notes to solidify the core facts, notice clue paths you might have missed during the match, and find pop‑culture hooks that make the material stick.

Study Notes

Question 1: NFL in Brazil & the International Series

GAMES/SPORT - The Philadelphia Eagles’ 34-29 Week 1 win over the Green Bay Packers in 2024 was the first NFL regular season game played in what country, the third country to host one outside North America and the first south of the equator?

The game was played in Brazil, at Arena Corinthians in São Paulo, on 6 September 2024, marking the NFL’s first-ever regular‑season game in South America and first in Brazil.(packers.com) Before that, the league’s regular‑season International Series had taken games outside North America only to the United Kingdom and Germany, so Brazil became the third non‑North‑American host country and the first in the Southern Hemisphere.(en.wikipedia.org)

Question 2: Sousaphone & John Philip Sousa

CLASS MUSIC - “The Stars and Stripes Forever”, “El Capitan”, and “The Liberty Bell” are among the first musical pieces to include what instrument, in no small part because they were composed by the man who originated its design?

The instrument is the sousaphone, a wrap‑around tuba created around 1893 by maker J.W. Pepper at the direction of American bandleader John Philip Sousa so that the bass voice could project over his band while being easier to carry than a concert tuba.(en.wikipedia.org) Sousa’s most famous marches—including “The Liberty Bell” (1893), “The Stars and Stripes Forever” (composed 1896, premiered 1897) and the operetta El Capitan (1896)—came from the same 1890s period when the sousaphone was being adopted into his ensembles.(en.wikipedia.org)

Question 3: Yeats’s “The Second Coming” & Achebe’s Things Fall Apart

LITERATURE - Turning and turning in the widening gyreThe falcon cannot hear the falconer;[REDACTED]; the centre cannot hold;Mere anarchy is loosed upon the worldWhat phrase is redacted from this opening of William Butler Yeats’s 1919 poem, and provides the title of what is often considered the most widely read book in modern African literature?

The missing phrase is “Things fall apart”, from W. B. Yeats’s 1919 poem “The Second Coming” (“Things fall apart; the centre cannot hold”), and Nigerian writer Chinua Achebe used it as the title of his 1958 novel Things Fall Apart.(poetryfoundation.org) Achebe’s debut, set in an Igbo community in colonial Nigeria, has sold over 20 million copies, been translated into more than 50 languages, and is frequently described as the most important or most widely read book in modern African literature.(en.wikipedia.org)

Question 4: Tequila, Jalisco & Denomination of Origin

FOOD/DRINK - The Mexican state of Jalisco’s various claims to fame include its status as the primary source of what trago, whose birthplace and namesake is a city approximately 40 miles northwest of the state capital, Guadalajara?

The drink is tequila, a distilled spirit made from blue Weber agave that has a protected Denomination of Origin restricting production to specific regions of Mexico—most centrally the state of Jalisco, where the town of Tequila gives the beverage its name.(en.wikipedia.org) The city of Tequila lies about 60 km (roughly 37–40 miles) northwest of Guadalajara and, together with the surrounding agave landscape and historic distilleries, is recognized by UNESCO as the “Agave Landscape and Ancient Industrial Facilities of Tequila” World Heritage Site.(en.wikipedia.org)

Question 5: Millennium Prize Problems & Million‑Dollar Math

MATH - The Yang-Mills existence, Navier-Stokes existence, Birch and Swinnerton-Dyer conjecture, and Hodge conjecture are all associated collectively with what prize?

These four problems are among the seven Millennium Prize Problems selected by the Clay Mathematics Institute in 2000; each carries a US$1 million prize for the first correct solution.(en.wikipedia.org) As of early 2026, only the Poincaré conjecture has been solved (by Grigori Perelman), so Yang–Mills, Navier–Stokes existence and smoothness, the Birch and Swinnerton‑Dyer conjecture, the Hodge conjecture, plus the Riemann Hypothesis and the P vs NP problem all remain officially unsolved.(en.wikipedia.org)

Question 6: Peppa Pig & the “Peppa Effect”

TELEVISION - Many American children reportedly began to develop English accents and adopt words and phrases such as “mummy”, “on holiday”, “telly”, and “ready, steady, go” due to COVID-19 lockdown-era binge watching of what animated series, headlined by a good-hearted four-year-old who loves jumping in muddy puddles?

The show is Peppa Pig, a British preschool animated series (first aired 2004) about Peppa, a four‑year‑old pig who lives with Mummy Pig, Daddy Pig and her little brother George and famously “loves jumping in muddy puddles.”(storymuseum.org.uk) During COVID‑19 lockdowns, heavy streaming of Peppa Pig in U.S. households led to widely reported anecdotes of the “Peppa Effect,” with American toddlers mimicking British accents and vocabulary such as “mummy,” “holiday,” “telly,” “satnav” and British pronunciations of words like “tomato” and “zebra.”(theguardian.com)
