Researchers hypothesize that granitic soil is the ideal construction material for the desert tortoise because it is not so hard that it makes burrowing difficult or so soft that it could cause tunnels to collapse.

(A) so hard that it makes burrowing difficult or so soft that it could cause

(B) hard enough to make burrowing difficult or soft enough as to cause

(C) so hard as to make burrowing difficult or soft enough so it causes

(D) as hard as to make burrowing difficult or as soft as to cause

(E) too hard, making burrowing difficult, nor too soft, so as to cause

Mr. Ahmann hypothesized that granitic soil was ideal for a tortoise because it was not too hard, which could make burrowing difficult, or too soft, which could cause tunnels to collapse. He said dirt high in calcium was frequently too hard and collected water.

A) it doesn't have a clear referent
B)as to is awkward in this context
C) not parallel
E) so as to is unidiomatic

so D is the only one that survives

"so as to" is not unidiomatic. it is perfectly idiomatic. rather "as .. as to" in D is unidiomatic.

contarary to the aboves, go with A cuz "so.. that" is correct expression..

Researchers hypothesize that granitic soil is the ideal construction material for the desert tortoise because it is not so hard that it makes burrowing difficult or so soft that it could cause tunnels to collapse.

A. so hard that it makes burrowing difficult or so soft that it could cause OK - "so X that" is the correct idiom because "that" allows for a subordinate clause to follow, and a clause is needed. Trap is the "so x that" clause, since it is not frequently used.

B. hard enough to make burrowing difficult or soft enough as to cause "hard enough to" or "soft enough as to" are not parallel; "hard enough" should be replaced with "as hard as" as to convey an equal degree

C. so hard as to make burrowing difficult or soft enough so it causes "so hard as to" and "soft enough so it" is not parallel

D. as hard as to make burrowing difficult or as soft as to cause "as hard as" and "as soft as" should be used between two nouns for proper comparison

E. too hard, making burrowing difficult, nor too soft, so as to cause "making burrowing difficult" or "so as to cause" are not parallel

Researchers hypothesize that granitic soil is the ideal construction material for the desert tortoise because it is not so hard that it makes burrowing difficult or so soft that it could cause tunnels to collapse.

A. so hard that it makes burrowing difficult or so soft that it could cause -> Correct
B. hard enough to make burrowing difficult or soft enough as to cause -> as breaks the parallelism
C. so hard as to make burrowing difficult or soft enough so it causes -> So X as Y is not a correct idiom."as X so Y" or "as X as Y" are correct usage. Also "soft enough" breaks the parallelism
D. as hard as to make burrowing difficult or as soft as to cause -> As X as Y is used to compare the similarities about X and Y and not provide reasons. So X that Y is a better construction
E. too hard, making burrowing difficult, nor too soft, so as to cause -> Combination of idioms doesn't correct the problem

I choose A. That is the only sentence which don't have any parallel issue.
As for D, " as hard as to" is unidiomatic. I only heard of " so as to". " as hard as" can be used for comparison but then again, we run into parallel issue: it is not as hard as it is to make - we need "it is" to make the sentence parallel.

i think in D, we are incorrectly comparing soil with hardness which is incorrect. it refers to soil....as hard as to make burrowing difficult or as soft as to cause

A, is correct because it refers to soil and soil is not so hard or so soft. we do not repeat not.

hope this helps.

C. is out because hardness is compared with burrowing.

I can see why people don't love A, but the "it" in A clearly refers to "soil." If you had any doubt about that, it might help to notice that "it" is already used for that purpose in the fixed portion of the sentence, and the GMAT will never switch antecedent for the same pronoun in the same sentence. In other words, once it=soil, that will remain true throughout the sentence, just like a variable in an equation.

There's also no problem with parallelism; we just shift from the simple present ("it makes") to a hypothetical ("it could cause"). It's perfectly fine to switch in this way when the meaning demands.

The odd thing is that we end up saying that the soil could make the tunnels (made of soil) collapse, but most other ways of saying this would run into problems, too. In the end, A is the only choice that works. (As others have stated, "as hard as to make" in D is not idiomatic.)

I think you mean "so X as to Y." That can work, although it's not the clearest way to say what we want to say. C has bigger problems, though. First, "soft enough so it causes" is not idiomatic. We need "soft enough to cause" or "so soft that it causes." Even if this were okay, it wouldn't be parallel with "so hard as."

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.

Experts, there is a lot of confusion pertaining to this one. Can you please elaborate why D is incorrect, and why A is the correct answer?
