Answer:
The correct answer is Él ve a la duquesa.
Explanation:
The important thing about this sentence is knowing how to locate the article.
Articles always accompany a noun with which they agree in gender (masculine, feminine) and number (singular, plural). In Spanish, there are two types of articles: indeterminate articles (un, una, unas, unas) and definite articles (el / los, la / las, lo).
The way in which this sentence would be correctly written would be:
Pronoun + verb + preposition + definite article + noun.
Él ve a la duquesa.
You say airport in Spanish “Avión”
The answer would be "sabes" it means "do you know" conoces mean also "do you know" but it refears if you know someone and sabes is if you know about something, "sabemos" means we know and "conosiste" means did you meet
