Hi Experts,

I have a couple questions regarding this sentence:

Choice C: so hard as to make burrowing difficult or soft enough so it causes -- I believe the issue here is parallelism. so "hard as to make" is not parallel to "soft enough so it causes".
Question - is the idiom "so X as to Y" correct? If we write choice C as - "so hard as to make burrowing difficult or soft as to cause ..." -- Would this be correct?

Choice E - In addition to parallelism issues. Is the usage of "nor" wrong here? Usually when presented in a list "nor" should be preceded by a "neither". Is the standalone "nor" usage incorrect here?

Thanks a lot for your help!

1. (A) it doesn't have a clear referent.
What else other than 'soil' can 'it' refer to logically? Can 'it' refer to the tortoise, meaning that tortoise is not hard for X and not soft for Y? So no doubt need be entertained about the ambiguity of the pronoun reference in A because logic is the leading light in such cases.
2. Why D is not equal to A.
D uses and infinitive as 'to make' burrowing difficult and as soft as to cause tunnels to collapse. the infinitive 'to make' implies that the action is not a finite action but at best a surmise or notion. On the other hand, A uses the subordinator 'that' using a clause with definitive action verbs 'makes' and 'could cause'. The premises of their hypothesis, in fact, are real happenings. This intention is rather feebly presented in D, making it depend upon some yet - to - happen notions rather than upon some real happenings as in A.. Therefore, it can be reckoned In D the original intent has been diluted, however grammatically normal it sounds.
Therefore, A IMO.
I have also seen that when a negative factor such as 'not' is involved, so…. as is used while in positive contexts as… as is used. Example:
Tom is not so tall as Dick
Tom is as tall as Dick.
This looks more like a convention than a decree.

Hi Daagh,

Can "as hard as" or "as soft as" be used as verb or noun phrase like it is used here in D?

Thanks!
