D. as hard as to make burrowing difficult or as soft as to cause

Welcome to discuss! Thanks.


regarding OR/NOR in the choices the matter is parallelism so , D is the answer

the OA is A,
but my question is why is "it makes burrowing" parallel to "could cause"?

Can anyone please help answer this question, thanks.

I had this question in my practice test. I also chose "D", but the right answer is "A". I guess that the problem of "D" is that it should be "as hard to make... as soft to cause.." and not "as x as to.."

I am not really sure, does anyone know the right reason why we should eliminate "d"?

One more for A. Close one between A and B. I would have chosen B if nor had been used instead of or.



"A"is the right answer, but I could not figure out why "D" is wrong. Does anyone know?
I guess that "as hard as to.." is unidiomatic and it would be better "as hard to".. but I'm not really sure.

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

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.

D - as ... as to is an incorrect idiom!
A is correct because so that is a correct idiom used correctly on both part of the sentence, also because here we need to use 'it makes' as singular & 'it could' as past.. As GMAT english goes always with the meaning first and not always with the grammer.. Here meaning says that 'could' must be used

I also have marked the option D as the correct answer and got the question wrong.

However, when i revisited the Question after appearing the exam and got the reason to choose answer Choice A over answer choice D.

I believe, As hard as X is correct idiom. If the answer choice had 'As hard as X to make.... or as soft as Y to ...', the Answer choice A would have been preferred over A.

I hope, i have understood the concept correctly. Please correct me if anyone finds any error in my reasoning.

Thanks!

I did not select D because it's not using "as hard as" correctly. You can say "as hard as a rock" but not "as hard as to make burrowing difficult", difference between those two is comparing two objects versus comparing an object to a result. Doesn't make sense.

Most people gloss over A because it sounds kind of funny, people don't really talk colloquially that way, but it's not incorrect either. Don't dismiss off gut only if you can help it :) GMAT knows what will be a "popular" gut check.

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.)

IMO A

Because 1) Not so hard ................ not So soft is the correct idiomatic representation.

Plus others have flaws in the sentence as discussed

B)Hard enough to make burrowing difficult makes sense in reverse context.
C) Both part of the sentence are not logically parallel
D)idiomatically correct but A is a better version (read concision)
E) Idiomatically wrong (Though, I marked it as the correct answer glancing through the answer choices )

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."

Hi,

DmitryFarber sayantanc2k

Any idea why the correct choice includes singular verb at one end and plural at other.

so hard that it makes burrowing difficult or so soft that it could cause

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


There are 5 clauses:

Clause 1: Researchers hypothesize (Independent clause)
Clause 2: that granitic soil is the ideal construction material for the desert tortoise (dependent clause)
(‘that’ acts as a connector between the two clauses)
Clause 3: because it is not so hard (dependent clause as it starts with ‘because’)
Clause 4: that it makes burrowing difficult (dependent clause)
Clause 5: or so soft that it could cause tunnels to collapse (dependent clause)

1) Every clause has its subject (bold) and verb (italics) pair and are correct.
2) The pronoun ‘it’ correctly refers to granitic soil.
3) The parallelism is correct in the original sentence: not so hard or so soft (not so hard or not so soft)
Answer is A.

I hope this understanding is correct.

not as hard as" needs to be followed by a noun, not an action; the usage of that phrase in D is incorrect.

as hard as to make burrowing difficult or as soft as to cause wromg
