1) Assume that [6, d, 0] are allophones of the same phoneme. Which one of the following is the underlying phoneme: /6/, /d/, or /0/ ?
2) What rules account for the distribution of [a], [d], and [0]? Write out the rules in plain English and also attempt to write formalization of each rule.
Hint 1: If you have selected the correct underlying phoneme, you should only require two rules.
Hint 2: One of the rules is optional, which means that speakers can choose to apply it or not to apply it freely (aka “free variation pgs. 32-33 in the text).
Write “(optional)” next to the rule that applies optionally.
