Problem: Alloy:

Alloying a metal is done by combining it with one or more other metals or non-metals that often enhance its properties. For example, steel is stronger than iron, its primary element. The electrical and thermal conductivity of alloys is usually lower than that of the pure metals. The physical properties, such as density, reactivity, Young's modulus of an alloy may not differ greatly from those of its elements, but engineering properties such as tensile strength and shear strength may be substantially different from those of the constituent materials. This is sometimes a result of the sizes of the atoms in the alloy, because larger atoms exert a compressive force on neighboring atoms, and smaller atoms exert a tensile force on their neighbors, helping the alloy resist deformation. Sometimes alloys may exhibit marked differences in behavior even when small amounts of one element are present. For example, impurities in semiconducting ferromagnetic alloys lead to different properties, as first predicted by White, Hogan, Suhl, Tian Abrie and Nakamura. Some alloys are made by melting and mixing two or more metals. Bronze, an alloy of copper and tin, was the first alloy discovered, during the prehistoric period now known as the bronze age; it was harder than pure copper and originally used to make tools and weapons, but was later superseded by metals and alloys with better properties. In later times bronze has been used for ornaments, bells, statues, and bearings. Brass is an alloy made from copper and zinc.

Who do smaller atoms exert a compressive force on?

Problem: Termed "the acoustic equivalent to Prozac", soft adult contemporary, a more adult-oriented version of AC, was born in the late 1970s and grew in the early 1980s. WEEI-FM in Boston was the first station to use the term "soft rock", with ad slogans such as, "Fleetwood Mac ... without the yack" and "Joni ... without the baloney". The vast majority of music played on soft AC stations is mellow, more acoustic, and primarily solo vocalists.
What processed meat, featured in WEEI-FM's ad slogan, rhymes with Joni?

Answer: baloney

The team placed fifth in the Premier League automatically qualifies for the UEFA Europa League, and the sixth and seventh-placed teams can also qualify, depending on the winners of the two domestic cup competitions i.e. the FA Cup and the Capital One Cup (League Cup). Two Europa League places are reserved for the winners of each tournament; if the winner of either the FA Cup or League Cup qualifies for the Champions League, then that place will go to the next-best placed finisher in the Premier League. A further place in the UEFA Europa League is also available via the Fair Play initiative. If the Premier League has one of the three highest Fair Play rankings in Europe, the highest ranked team in the Premier League Fair Play standings which has not already qualified for Europe will automatically qualify for the UEFA Europa League first qualifying round.
The team which has the highest ranking in the Fair Play standings is guaranteed qualification for which qualifying round in the Europa League?
A: first

Context and question: Late Carboniferous and Early Permian insect orders include both extant groups, their stem groups, and a number of Paleozoic groups, now extinct. During this era, some giant dragonfly-like forms reached wingspans of 55 to 70 cm (22 to 28 in), making them far larger than any living insect. This gigantism may have been due to higher atmospheric oxygen levels that allowed increased respiratory efficiency relative to today. The lack of flying vertebrates could have been another factor. Most extinct orders of insects developed during the Permian period that began around 270 million years ago. Many of the early groups became extinct during the Permian-Triassic extinction event, the largest mass extinction in the history of the Earth, around 252 million years ago.
Higher levels of what substance possibly contributed to the phenomenon of gigantism?
Answer: oxygen

Question: According to a study done by Helmut Fend (who had always been a fierce proponent of comprehensive schools) revealed that comprehensive schools do not help working class students. He compared alumni of the tripartite system to alumni of comprehensive schools. While working class alumni of comprehensive schools were awarded better school diplomas at age 35, they held similar occupational positions as working class alumni of the tripartite system and were as unlikely to graduate from college.
Is there an answer to this question: To which system didn't Fend compare comprehensive school alumni?

Answer: unanswerable

Arsenal appointed Herbert Chapman as manager in 1925. Having already won the league twice with Huddersfield Town in 192324 and 192425 (see Seasons in English football), Chapman brought Arsenal their first period of major success. His revolutionary tactics and training, along with the signings of star players such as Alex James and Cliff Bastin, laid the foundations of the club's domination of English football in the 1930s. Under his guidance Arsenal won their first major trophies victory in the 1930 FA Cup Final preceded two League Championships, in 193031 and 193233. In addition, Chapman was behind the 1932 renaming of the local London Underground station from "Gillespie Road" to "Arsenal", making it the only Tube station to be named specifically after a football club.
What was Herbert Chapman's last year as Arsenal's coach?
A:
