　　Questions 19-22
　　Along a street that is currently without trees， seven trees are to be planted in the pattern
　　1 3 5 7
　　2 4 6
　　Where each number designates the position of a tree. No
　　more than two kinds of trees can be planted. If maples
　　are used， no maple can be planted adjacent to or immedi-
　　ately diagonally opposite another maple. Two trees are
　　adjacent to each other if the numbers of their positions
　　differ by two， and immediately diagonally opposite if
　　their numbers differ by one. The following trees， of three
　　kinds， are available for planting：
　　Three red oaks
　　Four maples
　　Four sycamores
　　19.Which of the following can be the trees planted along
　　the side of the street that has four trees， in order of
　　their positions beginning with position 1？

　　（E）at most one red oak

　　23.A list of the fifteen operas most frequently performed
　　in recent times includes no works by the nineteenth-
　　century German composer Richard Wagner. Although
　　music producers tend to produce what audiences want，
　　relative infrequency of performance probably does
　　not indicate lack of popularity in Wagner's case， since
　　Wagner's operas are notoriously expensive to perform
　　on stage.
　　Which of the following， if true， most strongly
　　supports the conclusion of the argument above？
　　（A）The list of most frequently performed operas
　　does not include operas produced by small
　　amateur groups.
　　（B）Some opera companies are backed by patrons
　　who are willing to commit large sums of
　　money in order to enjoy lavish productions.
　　（C）All of the fifteen most frequently performed
　　operas of recent times are works that have
　　been popular for at least 75 years.
　　（D）More recordings have been produced recently of
　　the works of Wagner than of the works of any
　　other composer of opera.
　　（E）Operatic works of all kinds have been increasing
　　in popularity in recent years.
　　24.The bodies of dwarf individuals of mammalian
　　species are generally smaller in relation to those of
　　nondwarf individuals than are the teeth of the dwarf
　　individuals in relation to those of the nondwarf indi-
　　viduals. Fragmentary skeletal remains of an adult
　　dwarf woolly mammoth were recently found. The teeth
　　are three-fourths the size of the teeth of an average
　　adult nondwarf woolly mammoth.
　　The statements above， if true， most strongly support
　　which of the following？
　　（A）The body of the dwarf woolly mammoth was
　　less than three-fourths the size of the body of
　　an average adult nondwarf woolly mammoth.
　　（B）None of the teeth of the dwarf woolly mammoth
　　that were recently discovered was as large as
　　any of the teeth of nondwarf woolly mammoths
　　that have been discovered.
　　（C）The teeth of most adult dwarf individuals of
　　mammalian species are three- fourths the size of
　　the teeth of the adult nondwarf individuals of
　　the same species.
　　（D）Dwarf woolly mammoths had the same number
　　of teeth as did nondwarf woolly mammoths.
　　（E）Dwarf individuals of most mammalian species
　　are generally no more than three-fourths the
　　size of the adult nondwarf individuals of those
　　species.

25.Excluding purchases by businesses， the average　　amount spent on a factory-new car has risen 30 per-
　　cent in the last five years. In the average household
　　budget， the proportion spent on car purchases has
　　remained unchanged in that period. Therefore the
　　average household budget must have increased by
　　30 percent over the last five years.
　　Which of the following is an assumption on which
　　the argument relies？
　　（A）The average number of factory-new cars pur-
　　chased per household has remained unchanged
　　over the last five years.
　　（B）The average amount spent per car by businesses
　　buying factory-new cars has risen 30 percent in
　　the last five years.
　　（C）The proportion of the average household budget
　　spent on all car-related expenses has remained
　　unchanged over the last five years.
　　（D）The proportion of the average household budget
　　spent on food and housing has remained
　　unchanged over the last five years.
　　（E）The total amount spent nationwide on factory-
　　new cars has increased by 30 percent over the
