explanations? oh no. no no no nooooooo no.
(you must be relatively new here; i've made this point in many, many different places on this forum.)
the explanations are usually incomplete, and often actually wrong.the answer explanations were not written by the people who created the problems (presumably because those people's time is too valuable). rather, they were 'outsourced' to writers of considerably lesser ability, with predictable results.
one time when it's particularly important to keep this in mind is when the answer explanation mentions that something is 'wordy' and/or 'awkward'.
remember,
'wordy' and/or 'awkward' is NEVER the sole reason why a choice is wrong. (first, these things constitute bad writing, but they're not objectively
errors. second, if 'awkwardness' were a criterion, then the test would be fatally biased aganst non-native speakers of english, who are generally unable to acquire a sense of what is 'awkward').
