Answer 2

Have you ever seen an Ostrich in ____ house?

• The article ''a'' would be an erroneous choice because it refers to the entire species, not just any ostrich. Plus, 'an' would be used if it was about any ostrich bird.
• English has two articles: the and a/an.
• The is used to refer to specific or particular nouns, while a/an is used to modify non-specific or non-specific nouns.
• The is the definite article, while a/an is the indefinite article.
