黃金閱讀 RUNNING WATER ON MARS - 英檢

※ 引述《nash0227 (泡麵冰)》之銘言：
: 各位板友好
: 請問
: Furthermore, Mars Global Surveyor data released in 2003 seem to indicate that
: the Martian surface contains too few carbonate rock layers─layers containing
: compounds of carbon and oxygen─that should have been formed in abundance in
: an ancient ocean. Their absence supports the picture of a cold, dry Mars that
: never experienced the extended mild period required to form lakes and oceans.
: However, more recent data imply that at least some parts of the planet did in
: fact experience long periods in the past during which liquid water existed on
: the surface.
: 10. According to paragraph 4, what do the 2003 Global Surveyor data suggest
: About Mars?
: ○Ancient oceans on Mars contained only small amounts of carbon.
: ○The climate of Mars may not have been suitable for the formation of large
: bodies of water.
: ○Liquid water may have existed on some parts of Mars’ surface for long
: periods of time.
: ○The ancient oceans that formed on Mars dried up during periods of cold, dry
: weather.
: Ans:(B)
: 請問(A)哪裡錯?
: the Martian surface contains too few carbonate rock layers─layers containing
: compounds of carbon and oxygen─that should have been formed in abundance in
: an ancient ocean.
: 這句的意思不是說火星表面有很少的carbonate rock layers，而這個層應該在許多古代
: 的海洋中形成，所以(A)說的古代海洋只有一點點碳錯在哪呢?
: 麻煩各位板友解答了
: 謝謝!!
請問(C)哪裡錯?
他不是說
at least some parts of the planet did in fact experience long period...
所以C應該也是對的呀..
麻煩各位版友解答解答了..
感激不盡...

補充說明, 我剛剛去問一位老外
他說C才是正確答案呀..
B應該不是最適合的..
不知各位版友意見如何..
