Concept:The question tests recognition of identical vowel sounds in different words.
Explanation:The word "fear" is pronounced as /fɪə/.
The vowel sound here is /ɪə/, a diphthong.
"beer" is pronounced as /bɪə/, which contains the same vowel sound /ɪə/.
On the other hand, "bear", "swear", and "spare" are all pronounced with the vowel sound /eə/.
Therefore, "beer" matches the vowel sound of "fear".
