Guiderbook writer: i havevisited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that hotels built afterward. Clearly carpenters working on hotels before 1930 typically worked with more care, skill, and efforts than carpenters who have worked on hotels built subsequently.


Which of the following, if true, most seriously weakens the guidebook writer’s arguement ?


(A)The quality of original carpenters in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores.
(B)Hotels built since 1930 can generally accomendate more gusts than those built before 1930
(C)The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930

(D)The beter quality of original carpentry in a building, the less likely that building is fall into disuse and be demolished
(E)The average length of apprenticeship for carpenters has declined significantli since 1930




Codex Berinensis, a Florentine copy of an ancient Romen medical treatise, is undated but contains clues to when it was produced. Its first 80 pages are by a single copist, but the remaining 20 peges are by three different copist, which indicates some significant disrution. Since a letter in handwriting identified as that of the fourth copist mentions a plague that killed many people in Florence in 1148, Codex Berinence was probably produced in that year.


Which of the following, if true, most strongly supports the hypothesis that Codex Berinence was produced in 1148


(A)Other than Codex Berinence, there are no known samples of handwriting of the first three copist
(B)According to the account by fourth copist, the plague went on for 10 months
(C)A scribe would be able to copy a page of text the size and style of Codex Berinence in a day
(D)There was only one outbreak of plague in Florence in the 1100s

(E)The number of pages of Codex Berinence produced by a single scribe becomes smaller with each successive change of copist


The spacing of the four holes on a fragment of a bone flute ecavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatonic scale ---the seven-note musical scale used in much of Western music sice the Renaissance. Musiclogists therefore hypothesis that the diatonic musical scale was developed and used thousands of years before it was adopted by Western musicans


Which of the following, if true, most strongly supports the hypothesis ?


(A)Bone flutes were probably the only musical instrument made by Neanderthal
(B)No musical instruments that is known to have used a diatonic scale is of an earlier date than the flute found at the Neanderthal campsite
(C)The flute was made from a cave-bear bone and the campsite at which the flute fragment was excavated was in a cave that also contained skeletal remains of cave bears
(D)Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale
(E)The cave bera leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing a complete diatonic scale







The everage hourly wage of television assemblers in Vernland has long been significantly lower than in neighboring Borodia. Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold anually in Borodia has not changed. Howerer, recent statistics show a drop in the number of assemblers in Borodia. Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.


Which of the following is an assumption on which the arguement depends ?


(A)The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased
(B)Televisions assembled in Vernland have features that televisions assembled in Borodia do not have
(C)The average number of hours it takes a Borodian television assembler to assemblea television has not increased significantly during the past three years

(D)The number of televisions assembled annually in Vernland has increased significantly during the past three years
(E)The difference between the hourly wage of television assemblers in Vernland and the hourly wage of television assemblers in Borodia is likely to decrease in the next few years
