    34、 be theadministration of energy. This gives rise tothe social organism known as the ayllu, the(10) agrarian community that regulates the pro-curement of food. The ayllu formed the basicstructure of the whole Inca empire.The central idea of this organization was akind of closed economy, just the oppo

    35、site of(15) our economic practices, which can bedescribed as open. The closed economyrested on the fact that the Inca controlledboth the production and consumption offood.

    39、rld was also vanquished.(45) These considerations permit us to classifyQuechua culture as absolutely static or, moreaccurately, as the expression of a mere stateof being. Only in this way can we under-stand the refuge that it took in the germina-(50) tive center of the cosmic mandala as revealedby Q

    40、uechua art. The Quechua empire wasnothing more than a mandala, for it wasdivided into four zones, with Cuzco in thecenter.

    44、tion. The National Origins Quota System, which had been in effect since 1924, determined which immigrants should be allowed to come to the United States based solely on their national origin. The 1965 Immigration Act changed all this by making individual work skills and relationships with current U.

    45、S. citizens the criteria for immigration. President Johnson captured the essence of this exciting change by declaring that “those who can contribute most to this country-to its growth, to its strength, to its spirit-will be the first that are admitted to this land.“ The authors attitude toward the I

    46、mmigration Act is best characterized as one of A. resentment B. derision C. appreciation D. wonder E. confusion(分数:1.00)A.B.C.D.E.(5).A bag contains 3 red, 4 white, and 5 blue marbles.
