Adding plural nouns

Extend the DCG so that it will also be able to handle plural nouns. It should for example accept the following sentences

• the women fight
• nurses whistle
• the bride kills the killers

and reject the sentences

• the women fights
• a nurses whistle
• the bride kill the killers

(The agreement between subject and verb or between determiner and noun is not correct in the last two sentences.)
