premise: Abdessadeq Cheqara (1931 – October 31, 1998) (in Arabic: عبد الصادق شقارة) was a Moroccan singer of traditional Andalusian classical music and Moroccan folk music. Known as the "grand master of al-Ala (Andalusian music)", he was also a violin and oud virtuoso.
hypothesis: He was well-regarded in his field.
reason: He was known as 'the grand master', which suggests he was held in high esteem. The system probably didn't fully understand this phrase!
