choose the best spanish equivalent to the phrase. they know the old salesman. conocen al vendedor viejo. saben al vendedor viejo.
Answer
Brief Explanations:
In Spanish, "conocer" is used to mean "to know (a person or place)", while "saber" is used for knowing information or facts. Here, "they know the old salesman" implies acquaintance with a person, so "conocer" is the correct verb. Also, when referring to a masculine - singular person after a verb, "al" (a + el) is used.
Answer:
Conocen al vendedor viejo.
