A$.$ Parse the singular, singular definite, and plural nouns in $(1)$ into root plus suffix and isolate the alternations. For each alternation, justify your choice of an underlying representation. Formulate rules to account for the alternations. Must the rules be ordered? Provide derivations for the forms of 'sea'. $($Transcription notes: $,,$ are voiced fricatives, $d$ is a retroflex stop and $r$ is a retroflex fricative.$)$

B$.$The data in $(2),$ which we looked at earlier, require an additional rule. What is it$?$

C$.$ The data in $(3)$ show a vowel$-$zero alternation. Justify your choice of an underlying representation and formulate the rule to account for the alternation. Must the rule be ordered with any other rules? If yes, tell why for each ordering. Give derivations for the forms of 'mule' and 'hole'.

D$.$ The verbs in $(4)$ provide additional examples of the alternations already encountered. What underlying representations does your analysis assign to the verb roots and affixes? Illustrate how your analysis works by giving derivations for the forms of 'talk'.

E$.$ Does you analysis contain any rules that must be defined on intermediate levels of representation? Illustrate and discuss their theoretical significance.
