Correct Response: C. A schwah is a neutral, or lax, vowel sound, meaning that the tongue is in a neutral position in the mouth; it is not positioned front, back, high, or low. Schwah is a common vowel sound in English in unstressed syllables, such as the first syllable of words like ago and amaze or in the middle syllable of words like possible. Schwah is also the vowel sound of the common English final syllable –le . Thus, the word possible actually contains two schwah sounds. A, B, and D are incorrect because the given words contain a variety of vowel sounds but not the neutral vowel sound schwa.
