Read carefully through the paragraph below, and decide which of the options is correct. A shallow sea existed in North America approximately 425 million years ago.  This ancient geography was interpreted based on the sedimentary rocks in the region of that age. Mudstone, limely shale and shaley sandstone mark the location of the shallow sea.  Sandstone occurred near the ancient shoreline and conglomerate occurred near the source area.  Clasts of volcanic and plutonic rocks in the conglomerate imply the uplift and erosion of igneous rocks of nearby mountains.
A) The word " mudstone" should be replaced by " limestone".
B) The word " shallow" should be replaced by "deep".
C) The word "shale" should be replaced by " sandstone".
D) The word "igneous" should be replaced by "metamorphic".
