SUBJUNCTIVE MOOD

[navdeep_bajwa]

According to a recent study, hand sanitizers require a 60 percent minimum alcohol concentration for the killing of most harmful bacteria and viruses.

A require a 60 percent minimum alcohol concentration for the killing of
B require that there be a 60 percent minimum alcohol concentration to kill
C require that a 60 percent minimum alcohol concentration be present to kill
D require a 60 percent minimum alcohol concentration to kill
E require that there be a 60 percent minimum alcohol concentration for the killing of

why C is wrong isn't C represents subjunctive mood or its passive voice

Got a bit delayed to respond that IMO D. :)

Basically in subjunctive mood the verb represents either of these namely a demand,a command,a request,a statement of importance (such as suggest).
Here the verb require merely states a fact.

In a lighter sense,a good analogy can be the CR boldface question.Here a statement can be a premise (essentially just a fact,evidence) or a conclusion(essentially a kind of opinion - involves subjunctive). :)

Alternatively you may refer to :

this will definitely clear the cobwebs.

Happy GMATting.

first of all, (c) is a little bit weird. the whole thing with "present" is at best a circumlocution -- taking a lot of words to say what could be said in a few words -- and at worst conveys the wrong meaning: it seems to suggest that this alcohol concentration must already be present in order for the hand sanitizer to work.

also, it's unlikely that you'll be tested on this, but "require to" is normally used for actions with human subjects. here are some examples:
the company requires its employees to fill out the application in full.
the company requires that the application be filled out in full.
these may not be the world's greatest examples -- i just made them up off the top of my head -- but they convey the point: the use of "require ... to", in the first, is appropriate because the subject "employees" refers to humans. In the second, that constsruction wouldn't work, because the application is not a human being.

in any case, the latter paragraph here is a little bit too subtle for the gmat, in all likelihood. the weirdness of the wording is what truly kills the wrong answer here.

Are the following also correct along with the examples you gave:
1. The company requires that its employees fill out the form in full
2. The company requires the application to be filled out in full.

Thanks in advance.

Thanks in advance.

#1 would be fine, if a bit awkward.

#2 wouldn't work, for the reason cited above.

There's no way GMAC would ever test this.

Got it, thank you.

You're welcome.
