Hi,
From various sources including instructors on this forum (See:http://www.manhattangmat.com/forums/climatic-shifts-are-so-gradual-as-to-be-indistinguishable-at-t3570.html), I have gathered that the following idiomatic usage is correct -
So X [adjective] as to Y
For example: The soil erosion was so gradual as to be destructive for the nearby forest land.
Can someone explain if the following (related) usage is also idiomatic -
So X [adjective] that Y
For example: Hosani Mobarak was so despised that he was overthrown from his regime by his own people.
Thanks for your help.
