By the way—
For ANY usage in which regional differences exist, GMAC will provide proof of whatever is at issue.
E.g., check out #98 in the OG Verbal Supplement (can't reproduce here).
In that problem, "army" is singular, in accordance with standard American usage.
On the other hand, in many other countries, it's acceptable to write things like "The army are advancing". The GMAC writers, aware of these differences, have included the non-underlined "it" as indisputable proof that "army" is singular.
