: 謝謝~~~~

選項4沒錯 只是它是第一段在描述地下水循環時的其中一個環節 算是detail

選項6如果改成 beds of unconsolidated sediments can be found at inland sites
that were once underwater.就還可以考慮
但是它卻用typically這個字眼 整句話就變成 beds of.....【通常】都出現在 inland
site that were onec underwater
但是文章並沒有這樣的強調

而且第二段也提到

. Beds of this material, out of sight beneath the soil, are common. They are
found wherever fast rivers carrying loads of coarse sediment once flowed.
For example, as the great ice sheets that covered North America during the
last ice age steadily melted away, huge volumes of water flowed from them.
The water was always laden with pebbles, gravel, and sand, known as glacial
outwash, that was deposited as the flow slowed down.

所以beds of unconsolidated sediments還是有出現在其他地方
