During the past 1,000 years, the climates of the British Isles and continental Europe have undergone various episodes of change. It has long been believed that the demographic and economic expansion of Europe between the tenth and thirteenth centuries coincided with, and was perhaps encouraged by, a period of relative warmth , favorable to the expansion of cereal cultivation and the colonization of previously inhospitable environments. This benign phase, although variously dated, was seen to lie between a period of less favorable conditions in the late and post-Roman centuries and the so-called Little Ice Age of the early moderm period, which was characterized by an overall cooling of the climate and, in particular,by an increased severity of winters. Climatic deterioration was seen to have begun by circa 1300, presaged by an increase in stormy conditions in Europe, and associated with runs of wet and cool summers and the widespread harvest failures and livestock mortality of the years 1315-1322.

The integrity of the so-called medieval warm period, once considered a global phenomenon, has, however, been called into question by recent paleoenvironmental research. The picture that now emerges is of a less coherent and perhaps more geographically restricted phase—variously dated—of relative warmth, when temperatures in northwest Europe and the North Atlantic area were on average higher than in the post-Roman and early modern periods,although probably not warmer than in the late twentieth century.Some types of evidence, including the records of the advance and retreat of Alpine glaciers, suggest that the later fourteenth and early fifteenth centuries may have seen a notable climatic downturn,followed by a temporary amelioration around 1500, before renewed cooling into the Late Maunder Minimum period of 1675-1715.The relationship between glacial advance or retreat and temperature is,however, complex. A study of winter severity in central Europe during the fourteenth century found no clear trend, rather the altermation of runs of cold and mild winters, with the most sustained period of severe winters falling in the period 1301-1328.English documentary sources have been used to suggest a cooling trend from circa 1240-1340, with a subsequent amelioration followed by renewed cooling from circa 1510, but the sporadic nature of this data series necessitates caution. A long-term cooling trend in the northern hemisphere between the twelfth/thirteenth and the seventeenth centuries does, however, emerge from a plethora of sources,including tree-ring data, the study of lake and ocean sediments, and analysis of Greenland ice cores.

which of the following can be inferred from the passage about the"period of relative warimth""?

lt may not have begun until the early moderm period. lt was probably not responsible for increases in European cereal cultivation. It appears to have occured across a less extensive area than was once thought.

1. 关于"相对温暖期"的推断：
  - It may not have begun until the early modern period. 这个说法未必正确，因为文章中可能没有提到相对温暖期的确切开始时间。
  - It was probably not responsible for increases in European cereal cultivation. 这个说法也未必正确，因为文章中可能未涉及相对温暖期对欧洲谷物种植增加的讨论。
  - It appears to have occurred across a less extensive area than was once thought. 这个说法可能是正确的，因为文章提到相对温暖期并不像过去认为的那样广泛，显示出地区性变化而非统一的气候变化。
  因此，从文章内容推断，最符合的选项是：它似乎发生在比之前认为的范围更为有限的地区。
