1. B is out because WERE (a consistency)
D is out ARE
E sounds bad...
A i'm not sure what's wrong (HELP)

2. you need to understand the point (logic) of the sentence, the NAT want to united families because NOT ALL their members are... so A,C,E out
D is awkward so B

In the first one, I go with A.

The clause "that was once thought to be" presented in C sounds awkward to me, while "as once thought to be" in A sounds fine.

Also, in C, the word order "achieving in farm animals a consistency of quality and production" is weird. IMO, it should be "achieving (What?) a consistency... (Where?) in farm animals".

i think the first one OA : C is incorrect when achieving in is incorrect idiom.

IMO: D, "are" for consistancy of quality and production "are" -right verb use.

in the second,
A is fault meaning. if all members cannot unqualify 5 years reside but some.

B is right meaning.

So does this mean that the gmat prep's answer is wrong ?

Can we have the experts comment on the first question please ?
