No articles at all in Klingon. There are actually many Earth languages that do not use articles and translators have to learn how to decide when to add an article into the English and which article to add. Context can make it quite clear. If I am introducing a new topic, you will probably use an indefinite article, but if I am continuing to talk about a previous topic, you will probably use a definite article. But since most of these sentences are out of context, either the definite or indefinite articles will be accepted as long as they make a valid English sentence.
