Determiner agreement and noun conjunction

Determiner-noun agreement in English and many other languages appears to be straightforwardly describable; singular determiners go with singular nouns, and plural determiners go with plural nouns. The situation is more complicated with coordinated nouns, however, since unexpected agreement patterns often result. Our theory makes the correct predictions for English and other languages by combining two crucial insights: the dual nature of agreement features inside the noun phrase (Kathol 1999; Sadler 1999, 2003; Wechsler & Zlatić 2000, 2003) and the distinction between distributive and nondistributive features in coordination (Dalrymple & Kaplan 2000)
