A divide between aesthetic and technical considerations has played a crucial role in mapmaking and cartographic scholarship. Some nineteenth-century cartographers, for instance, understood themselves as technicians who did not care about visual effects, while others saw themselves as landscape painters. That dichotomy structured the discipline of the history of cartography. Until the 1980s, in what Blakemore and Harley called "the 'Old is Beautiful' paradigm.* scholars largely focused on maps made before 1800. marveling at their beauty and sometimes regretting the decline of the pre-technical age. Early mapmaking was considered art while modem cartography was located within the realm of engineering utility. Alpers. however, has argued that this boundary would have puzzled mapmakers in the seventeenth century, because they considered themselves to be visual engineers.

According to the passage. Alpers would say that the assumptions underlying the "paradigm" were

Larvae of many marine invertebrate species delay their metamorphosis into juveniles when cues signaling an appropriate juvenile environment are absent, thereby increasing their likelihood of thriving as juveniles and of ultimately reaching adulthood Nevertheless, delayed metamorphosis has potential costs for juveniles including reduced growth and increased mortality Nearly all evidence of such costs involves species whose larvae do not feed but rather subsist on stored nutrients, indicating that insufficient energy reserves may be an underlying cause of these costs. Supporting this hypothesis are laboratory studies showing that in a certain bryozoan. the prolonged larval swimming that results from delayed metamorphosis is associated with size reductions in the juvenile feeding organ (the lophophore) and that one factor influencing the size of juveniles of certain barnacle species is how long larvae delay metamorphosis However, other studies show that while significantly fewer juvenile Capitella worms survived to adulthood when metamorphosis had been delayed, prolonged larval swimming had no significant effect on juvenile size, suggesting, perhaps, that in some species, factors other than insufficient energy reserves account for the negative effects of the larval stresses that result from delayed metamorphosis.

The passage suggests that the, "bryozoan." the "barnacle species.'" and 'Capitella worms" all share which of the following characteristics?

The term "ragtime opera" was used frequently m the first years of the twentieth century, but more often than not its use was (i)_________. The very idea of "ragtime opera" was viewed as lii)_________: opera was regarded as the highest form of musical art; ragtime was at the opposite pole.
