[請益] 黃金閱讀 Depletion of the Ogallala Aquifer

[cinqjoy (5JOY)]

Paragraph 1：
The vast grasslands of the High Plains in the central United States were
settled by farmers and ranchers in the 1880’s. This region has a semiarid
climate, and for 50 years after its settlement, it supported a low-intensity
agricultural economy of cattle ranching and wheat farming. In the early
twentieth century, however, it was discovered that much of the High Plains was
underlain by a huge aquifer (a rock layer containing large quantities of
groundwater). This aquifer was named the Ogallala aquifer after the Ogallala
Sioux Indians, who once inhabited the region.

1．According to paragraph 1, which of the following statements about
   the High Plains is true?

○Until farmers and ranchers settled there in the 1880’s, the High Plains
  had never been inhabited.
○The climate of the High Plains is characterized by higher-than-average
  temperatures.
○The large aquifer that lies underneath the High Plains was discovered by the
  Ogallala Sioux Indians.
○Before the early 1900’s there was only a small amount of farming and
  ranching in the High Plains.

我選B 答案是D

選B是因為我看到This region has a semiarid climate

有人可以解惑嗎?謝謝!
