A. we should replace chips and sweetened soft drinks with healthier raw veggies, fruits, whole-grain biscuits and low-fat cheese. - use of should is incorrect with "suggest"
SUGGEST can be used in conjunction with SHOULD/MUST/WILL/MIGHT/CAN etc. This is NOT a repetition.
A search for ""suggest that we should"" gives 12M results in google.
If that doesn't convince you, look at
OG 12 question number 13.
Intresting....
But please could you elaborate what exactly you are trying to say?
Thanks,

First take a look at the rules about command subjunctive:
Command subjunctive mood is used alongwith certain bossy verbs such as demand, require, propose etc. When such verbs are used the action that is demanded / required /proposed should take the command subjunctive mood, i.e. the raw form of verb, the form you would use to command someone something. e.g.
Be physically fit, Arunpriya!
I demand that you
be physically fit.
Here
demand is the bossy verb, and it requires a command subjunctive mood for the action demanded (
be).
Another example ..... observe that the usage of simple present is wrong in the second sentence below!
Close the department !
The management requires that the department close....right.
The management requires that the department closes....
wrong !!The management requires that the department should be closed... wrong again !
Here
requires is the bossy verb, and it requires a command subjunctive mood for the action required (
close)
Now coming back to your query.......
TheGMATGameRussia is trying to say that we
can use
should instead of the hypothetical subjunctive alon with a bossy verb - i.e. following usage is correct:
The management requires that the department should be closed.
It is true that the above usage is seen in British English, but in strict GMAT terms generally the command subjunctive form is valid with a bossy verb. Nonetheless as TheGMATGameRussia pointed out the British style may have been used in a rare occasion - cannot cross-check since I do not have the OG12.
