Praxis 5002 Practice Test Practice Question

Which THREE of the following words contain diphthongs?

Correct Answer: A,C,E

Rationale: Diphthongs are complex vowel sounds that begin with one vowel sound and glide into another within the same syllable.

Option A, "Boy," contains the diphthong /ɔɪ/, where the sound transitions from the "o" to the "y." Similarly, option C, "Buy," features the diphthong /aɪ/, transitioning from "a" to "y." Option E, "Coin," includes the diphthong /ɔɪ/, moving from "o" to "i."

In contrast, option B, "Mother," has a single vowel sound /ʌ/ and does not feature a glide, while option D, "Apple," contains the vowel sound /æ/ and also lacks a diphthong. Thus, A, C, and E are the correct choices.
