"If fruits would not be sweet we would not have eaten them"
Translation:Matunda yasingekuwa matamu tusingeyala
The tenses don't match in the English translation. 'Were the fruits not to have been sweet' or, more concisely, 'had the fruits not been sweet' would match '... would not have eaten...'
'If fruits would not be...' expects '...would not eat them'.
Thank God I'm almost at the end of this skill...
