To develop auditory discrimination, a teacher prepares sentences containing English words that differ by one sound. Students listen to each sentence and identify the word they hear. Match the word pairs in Column I with the phonological contrast described in Column II.

Column         I
1.Ship   /  Sheep 2.Fan    /   Van 3.Rice    /  Rise 4.Bet      /  Bat

Column II

I.Contrast between voiced and voiceless consonants.
II.Contrast between a short front vowel and a long front vowel.
III.Contrast involving the final consonant sound.
IV.Contrast between two front vowel sounds.

Select the alternative that presents the correct matching.
