Concept:A word can be matched to a sound only when the target phonetic symbol is known.Explanation:The given phonetic symbol is not shown in this question.So it is not possible to compare that sound with the vowel sounds in the options.For reference, the options have different vowel sounds:pour = /pɔː/count = /kaʊnt/tour = /tʊə/dear = /dɪə/Since the target sound is missing, no single option can be identified as the correct one.Answer:Cannot be determined because the phonetic symbol is missing.
