如題
想請問這篇閱讀的最後一題summary,選項如下:
○Sediments that hold water were spread by glaciers and are still spread by
rivers and streams.
○Water is stored underground in beds of loose sand and gravel or in cemented
sediment.
○The size of a saturated rock’s pores determines how much water it will
retain when the rock is put in a dry place.
○Groundwater often remains underground for a long time before it emerges
again.
○Like sandstone, basalt is a crystalline rock that is very porous.
○Beds of unconsolidated sediments are typically located at inland sites that
were once underwater.
答案是123 我選了234
我不懂4是錯在哪邊??
有誰可以幫我解答一下嗎?? >"<
