"A pair of architects in Britain, (...) , and already designed/and they have already" are wrong, the last part cannot follow the first part. Subject , (...), verb is the structure. The same reasoning can be applied to D.
Only C and E respect that structure. E is not the correct answer because:1) comparison "giant arches made of artificial bone could be easier to design than with conventional structures" 2)use of "which" that modifies "bridge" (which cannot show how their idea works).
now this is GMAT like question....and preety well explained by Zarrolou,,but i am also not clear whether a pair of architects is singular or plural..
although i know " a set of mutants" is singular...but here where i am going wrong.
Zarrolou and Daagh ...i request to explain this.
thanks

Please explain why and is wrong in B and already wrong in D
hi rrkan,
the original given sentence is as follows:
A pair of architects in Britain,
who say that giant arches, bridges, and walls made of artificial bone could be easier to design and [u]build than conventional structures, and already designed a number of structures, including a bridge, for showing how their idea would work.
the coloured part starting with "who say .....than conventional structures"...actually this whole part is acting as a modifier and it is modifying a pair of architects.
now good thing with modifier is that if you remove the modifier from the sentence then also sentence must make sense.
now lets remove this modifier and hence resulting sentence will become like this:
A pair of architects in Britain and already designed a number of structures, including a bridge, for showing how their idea would work.
now reading the sentence do you think does this makes sense.
the use of parallelism marker AND conveys that both side of the and should be parallel but here
A pair of architects in Britain
and
already designed a number of structures
is not parallel ALSO THERE IS NO MAIN VERB TOO IN THIS SENTENCE.
hence use of and is wrong. in the same way option B is also wrong.
again now in option D after removing the modifier the resulting sentence becomes:
A pair of architects in Britain already designed a number of structures, including a bridge,which shows how their idea would work.
now if you read the above sentence then you will find that there is no verb in the sentence for the subject "a pair of architect"
and the use of HAVE before already rectifies this error which is done in option C.
so in this case use of already is not wrong but rather highlighted already indicates that a verb is required before already.
