PROBLEM: Passage: The softness of copper partly explains its high electrical conductivity (59.6×106 S/m) and thus also high thermal conductivity, which are the second highest (to silver) among pure metals at room temperature. This is because the resistivity to electron transport in metals at room temperature mostly originates from scattering of electrons on thermal vibrations of the lattice, which are relatively weak for a soft metal. The maximum permissible current density of copper in open air is approximately 3.1×106 A/m2 of cross-sectional area, above which it begins to heat excessively. As with other metals, if copper is placed against another metal, galvanic corrosion will occur. Question: What is the explanation for copper's capacity for electrical conductivity?

SOLUTION: The softness

PROBLEM: Passage: Modern adult contemporary can be a variation of hot AC, and includes modern rock titles in its presentation. In 1997, Mike Marino of KMXB in Las Vegas described the format as reaching "an audience that has outgrown the edgier hip-hop or alternative music but hasn't gotten old and sappy enough for the soft ACs." The format's artists included Alanis Morissette, Counting Crows, Gin Blossoms, Bon Jovi, Train, No Doubt, The Script, The Cranberries, Lifehouse, Sarah McLachlan, Sara Bareilles, John Mayer, Jewel, and Ingrid Michaelson. Unlike modern rock, which went after 18-34 men, this format appealed to women. Question: What age demographic is modern rock radio focused on?

SOLUTION:
18-34
