CR 1 Power Records, a music chain store, discovered that playing rock music in its stores increases sales of rock albums and that playing classical music leads to an increase in sales of classical music albums. Therefore, in order to increase sales of pop singer Frenchie Pear's new CD, her latest single Dazed and Confused should be constantly played in all Power Records stores.
The above argument relies on which of the following assumptions?
(A) Pop music is similar to rock music.
(B) All of Frenchie Pear's previous singles that were played in Power Records stores sold well.
(C) The said sales technique also works for specific songs.
(D) Frenchie Pear's latest single has received rave reviews.
(E) Power Records sells more pop albums than any other music chain store does.

CR 2 Due to oxidation, the iron components that are utilized in structures formed with reinforced concrete can potentially lose their strength over time, especially in coastal areas with high humidity levels. This phenomenon can be prevented by coating the iron components with a robust secondary substance, such as a polymer with anti-oxidant properties. Therefore, it is certain that buildings constructed in areas with high humidity using reinforced concrete that contains uncoated iron components will suffer structural damage in the form of corrosion due to oxidation.
Which of the following, if true, undermines the author's conclusion?
(A) Only when reinforced concrete is mixed disproportionately does it experience a more dramatic chemical reaction, leading to the release of abnormal amounts of heat, and as a consequence, becomes cracked, exposing its inner iron structure to the atmosphere.
(B) A range of polymer products with anti-oxidant properties are readily available from suppliers of construction equipment, but are almost always fairly expensive due to the chemical processes and patents required to produce such products commercially.
(C) Because of harsher conditions such as above-average moisture levels, strong winds, and higher exposure to sunlight, building materials tend to suffer structural disintegration at much higher rates in coastal areas than in areas that are further inland.
(D) Cracking is an inevitable result when concrete is used in large volumes, but if the inner iron components are protected by an epoxy or zinc phosphate layer, and if the cracks are treated early enough, serious weakening of the structure should not not take place.
(E) Building projects constructed in coastal areas are usually highly lucrative, and accordingly have higher budgets and the financial potential to invest in superior materials, such as coated iron components for structures built with reinforced concrete.
