I will go with C "in contrast with". Any reason why this shouldnt be true?

one advantage of ..... is that the contact [is effected cont over a board] rathar than at a seriers

one advantage of ..... is that the contact [is effected cont over a board] in contrast with a seriers

Contact at a series of regularly spaced points is better that with a series of regularly spaced points

Hope this help!

I want coffe instead of tea .
rather than -- used to preference.

A)
= ...advantage of X over Y is that the contact.. is effected continously "over a broad surface" (O) instead of
"a series of regulary spaced points..." (S)
O and S are not parallel. also "instead of" is incorrec here.

D) ...advantage of X over Y is that the contact.. is effected continously "over a broad surface" (O) rather than
"at a series of regulary spaced points..." (S)
O and S are ll... and also rather than makes sense here.

correct me if i am wrong

this is not a prallelism question. this is purely a meaning based question.

option A misses out the preposition at, which is necessary to describe where the bonding is affected. ‘is effected continuously over a broad surface rather than (at) a series of regularly spaced points with no bonding in between’. We need something to pin point a location which can only be done by ‘over’, ‘on’, ‘in’ and ‘at’.

'and hence the bonding, is a non-essential modifier in the midddle.

I selected B because it brings in a contrast. Why is B wrong. I believe its making more sense by meaning and its parallel too. Please some one throw some light on this [58 sec]

"in contrast to " is the correct idiom.

(D) rather than at
(E) as against being at

Source --> OG 10

I understood
A - Wrong, Because a contrast is needed in this sentence so instead of is not appropriate
C - Wrong, In contrast with -- Unidiomatic
E - Wrong, Being not correct

Now i am confused between Option B and D, I feel Option B could have also been helpful in reflecting the contrast and thus the right answer.

From the GMAT point of view, I think the important Idioms are: 'Instead of' and 'rather than'. The Idioms 'In contrast to' and 'As opposed to' are not as important as the former in GMAT. This distinction would have been unnecessary, but for the fact that meanings of 3 out of the 4 idioms above are fairly similar. So strictly from the GMAT POV, I would chose 'Rather than' if I knew for sure 'Instead of' is incorrect AC.

Taking the sentence out of the GMAT Context I would definitely prefer B - 'As opposed to' over 'Rather than at'.

If an expert can shed some light over the usage then it will be really helpfull.

One more reason that I think goes in favour of D is Parallelism.

Sentence:
In metalwork one advantage [strike]of adhesive-bonding over spot-welding[/strike] is that the contact[strike], and hence the bonding,[/strike] is effected continuously over a broad surface instead of a series [strike]of regularly spaced points with no bonding in between[/strike].

I have struck out all the Middle Men.
Now to maintain the Parallelism, the correct structure should be:
Phrase starting with Preposition < Idiom > Phrase starting with preposition.
Option A: Does not maintain the above structure as 'Instead of' is the preposition and hence the phrase does not start with a preposition
Option B: Same problem structure is not maintained because 'As opposed to' entirely is the idiom.
Option C: Same problem structure is not maintained because 'In contrast to' entirely is the idiom.
Option D: CORRECT - The structure is perfectly maintained as 'Rather Than' is the idiom and hence the next Phrase begins with the preposition 'At'

Aside the fact that the big boss always prefers rather than over instead of, beyond GMAT too I will rather not like to use expressions such as opposed to and as against in issues of comparison. In my opinion and as per custom, you can use as against or as opposed to when you are opposed to or against something materially or conceptually. The element of dislike or repudiation should be innate in such contexts. For example, when I say that I am opposed to smoking either within office or in the public or when state that I am against public display of affection, I am meaning to say that I just don’t like them. But you can not use the same expressions to say tha admission in business schools this year has been nearly 150 thousand as opposed to or as against 100 thousands last year as if the relevant years are fighting between themselves. In these cases. proper diction requires to say that admission in business schools has been nearly 150 thousand this year in comparison to ( or as compared to or in contrast to blah, blah )100 thousand last year. Have I made my point?

E is out "being"
B is awkward out
C - "in contrast with" is used to compare like things. It is inappropriate in this context
A - instead of cannot be used to compare clauses

D remains.

Moreover the comparison is

bonding is effected continuously over a broad surface rather than at a series of regularly spaced points

How to decide between instead of and rather than here??
I think the verb is effected makes it necessary to use rather than and not instead of.

Experts pls comment on that.

‘Instead of’ means ‘in the place of’. In contexts when we have a dilemma of choosing between one or the other 'rather than' is more befitting.

In metal work one advantage of adhesive-bonding over spot-welding is that the contact, and hence the bonding, is effected continuously over a broad surface in the place of a series of regularly spaced points with no bonding in between

We can see how 'rather than' fits in better. I have hardly seen 'instead of' being approved by GMAT in such circumstances.
