んがため vs. べく help


Why does my textbook give 売らんがための as the phrase for ____ in
この雑誌には＿＿＿誇張表現が多いようだ and not 売るべく? From the usage info they give, either should
work as both have volitional verbs before the ___. Is it that 表現が多いようだ is not
expressing volition that makes 売るべく not appropriate? Thanks.




売るべく works adverbially, 売らんがため **の** works adjectivally (and 売らんがため without の
works adverbially). The modified phrase, 誇張表現, is a noun phrase, so it should
be modified by an adjectival expression.
