To determine which guidewords would appear on the same dictionary page as the word "infer," we should look for guidewords that are alphabetically adjacent to "infer."
The word "infer" begins with "in" and is alphabetically arranged among words that also start with "in." Now, let's examine the options:
- inept/infantry - "inept" is before "infer," and "infantry" is after, so this pair is a possibility.
- infinitude/informatics - "infinitude" comes after "infer," so this pair is not valid.
- infantryman/infinitive - "infantryman" comes after "infer," making this pair invalid.
- induction/ineluctable - "induction" is before "infer," and "ineluctable" is after, so this pair is also valid.
Considering the pairs, both "inept/infantry" and "induction/ineluctable" would be possible guidewords. However, typically you'll look for guidewords that bracket "infer," and "inept/infantry" is more adjacent.
So the correct answer would be:
inept/infantry
