Question: Yale seniors at graduation smash clay pipes underfoot to symbolize passage from their "bright college years," though in recent history the pipes have been replaced with "bubble pipes". ("Bright College Years," the University's alma mater, was penned in 1881 by Henry Durand, Class of 1881, to the tune of Die Wacht am Rhein.) Yale's student tour guides tell visitors that students consider it good luck to rub the toe of the statue of Theodore Dwight Woolsey on Old Campus. Actual students rarely do so. In the second half of the 20th century Bladderball, a campus-wide game played with a large inflatable ball, became a popular tradition but was banned by administration due to safety concerns. In spite of administration opposition, students revived the game in 2009, 2011, and 2014, but its future remains uncertain.
Is there an answer to this question: What statue is it rumored to be bad luck to rub?

Answer: unanswerable

Question: Several molecular mechanisms of antibacterial resistance exist. Intrinsic antibacterial resistance may be part of the genetic makeup of bacterial strains. For example, an antibiotic target may be absent from the bacterial genome. Acquired resistance results from a mutation in the bacterial chromosome or the acquisition of extra-chromosomal DNA. Antibacterial-producing bacteria have evolved resistance mechanisms that have been shown to be similar to, and may have been transferred to, antibacterial-resistant strains. The spread of antibacterial resistance often occurs through vertical transmission of mutations during growth and by genetic recombination of DNA by horizontal genetic exchange. For instance, antibacterial resistance genes can be exchanged between different bacterial strains or species via plasmids that carry these resistance genes. Plasmids that carry several different resistance genes can confer resistance to multiple antibacterials. Cross-resistance to several antibacterials may also occur when a resistance mechanism encoded by a single gene conveys resistance to more than one antibacterial compound.
Is there an answer to this question: What is part of hje the make up of bacterial strains?

Answer: Intrinsic antibacterial resistance

Question: The Appalachian Mountains (i/plen/ or /pltn/,[note 1] French: les Appalaches), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period and once reached elevations similar to those of the Alps and the Rocky Mountains before they were eroded. The Appalachian chain is a barrier to east-west travel as it forms a series of alternating ridgelines and valleys oriented in opposition to any road running east-west.
Is there an answer to this question: What language does the name of the Alps come from?
