("美国西北部的俄勒冈州因其独特的地理位置和气候条件而成为美国最大的榛子产地。这里出产的榛果占全美产量的99%，其中一半用于出口，包括中国。过去5年来，种植榛子的美国农民平均每年获得的收益接近1亿美元")

Note:
(a) There is no need to read the rest, which does not say ANYTING -- not even explaining what 机会 is.
(b)
(i) "The hazel (Corylus) is a genus of deciduous trees and large shrubs native to the temperate Northern Hemisphere." en.wikipedia.org for hazel.
(ii) "The hazelnut is the nut of the hazel and therefore includes any of the nuts deriving from species of the genus Corylus, especially the nuts of the species Corylus avellana. * * * In the United States, Oregon accounted for 99% of the nation's production in 2014, having a crop value of $129 million that is purchased mainly by the snack food industry."  en.wikipedia.org for hazelnut (citation omitted).

(c) I fail to find out what is unique about Oregon that explains about its advantages, except "temperate ocean, mountain and river climates meet with rich volcanic soils to create prime hazelnut-growing country." Oregon Hazelnut Industry
(oregonhazelnuts.org).
