Commonly confused with
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones ～にほかならない is tested against.
vs にすぎない
にほかならない emphasizes 'it is precisely this (and nothing else)' with conviction; にすぎない downplays something as 'merely / nothing more than', a limiting nuance.
vs というものだ
にほかならない pinpoints the sole identity/cause; というものだ gives a general evaluative conclusion about what something amounts to.
