With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Sunni and Shia hadith collections differ because scholars from the two traditions differ as to the reliability of the narrators and transmitters. Narrators who took the side of Abu Bakr and Umar rather than Ali, in the disputes over leadership that followed the death of Muhammad, are seen as unreliable by the Shia; narrations sourced to Ali and the family of Muhammad, and to their supporters, are preferred. Sunni scholars nonetheless put trust in the factual accuracy offered by narrators such as Aisha, whom the Shia vocally accept. Differences in hadith collections have contributed to differences in worship practices and shari'a law and have hardened the dividing line between the two traditions.
text_B: From this passage, could someone mostly unschooled in Islam conclude that Aisha was on the side of Ali?
YES.
