Choose the correct imperfect form of ser for the subject 'ellos'.

• A. Era
• B. Eras
• C. Éramos
• D. Eran

Answer: (D)

In the imperfect tense, the verb ser changes by person. For ellos (they), the form is eran. This comes from the set: era, eras, era, éramos, erais, eran—the third-person plural form is eran. So "Ellos eran ..." means "They were ..." or "They used to be ..." in a past, ongoing sense. The other forms don’t fit because they correspond to different persons: era is singular (he/she/you), eras is second person singular (you), éramos is first person plural (we), and erais is second person plural (you all). The accent in éramos marks the first-person plural form, which isn’t used with ellos.
