A primary value in early twentieth-century Modernist architectural theory was that of “truth to materials”, that is, it was essential that a building’s design express the “natural” character of the building materials. This emphasis would have puzzled the architects of the Italian Renaissance (sixteenth century), a period widely regarded as the apex of architectural achievement, for Renaissance architects’ designs were determined only minimally by the materials employed. The diversity of Italy’s natural resources provided Renaissance architects with a wide variety of building materials. The builders of the Pitti Palace (1558-1570) used great blocks of Tuscan stone, just as Etruscans living in the same part of Italy had done some twenty centuries earlier. Had the Florentine Renaissance builders aped the Etruscan style, it might be said that their materials determined their style, since Etruscan style matched the massive, stark, solid character of the stone. But these same materials, which so suited the massive Etruscan style, were effectively used by the Florentine Renaissance to create the most delicate and graceful of styles.
A similar example of identical materials used in contrasting styles characterizes the treatment of Roman travertine marble. When Baroque architects of seventeenth-century Rome desired a massive and solid monumental effect, they turned to travertine marble, whose “natural effect” is, indeed, that of spacious breadth and lofty, smoothly rounded surfaces. Yet during the Renaissance, this same material had been used against its “nature,” in the Florentine tradition of sharply carved detail. Italian Renaissance architecture was shaped less by the “nature” of the materials at hand than by the artistic milieu of Renaissance Italy, which included painting and sculpture as well as architecture. While Roman travertine marble may have lent itself to fine carving, the Florentine passion for fine detail is no less marked in Florentine Renaissance painting than in Florentine Renaissance architecture. Similarly, in the next century, the emphasis on shading and corporeal density in Baroque painting mirrored the use of Roman travertine marble in Baroque architecture to create broad shadow and powerful masses.
The ingenuity of Renaissance architects extended beyond merely using a material in a way not suggested by its outward natural appearance. If they conceived a design that called for a certain material either too expensive or difficult to work with, they made no scruple about imitating that material. Their marbles and their stones are often actually painted stucco. When the blocks of masonry with which they built were not in scale with the projected scheme, the real joints were concealed and false ones introduced. Nor were these practices confined, as some scholars insist, to the later and supposedly decadent phases of the art. Material, then, was utterly subservient to style.

4. The passage suggests which of the following about the cited “scholars”?
A. They believe that a decadent phase is characteristic of any significant artistic movement.
B. They reject the popular view of the Renaissance as the apex of architectural achievement.
C. They believe that a vigorous and healthy architecture would not usually employ false surfaces or
imitation building materials.
D. They represent the mainstream in critical and historical thought about the Florentine
Renaissance.
E. They have focused on such technical matters as the cost of building materials rather than on
artistic concerns.
key:C

这道题该怎么做呢？不是很理解为什么选C, vigorous and healthy 在哪里体现的呢？

谢谢！~

vigorous and healthy 和 decadent 相反对应
前面提到的改变材料本身性质或者用假的材料这些practices were not confined to decadent phases of the art. 插入语as some scholars insist

我觉得负态度用decadent phrase来体现有点牵强诶，万一这是一个专有名词呢....（晕
