Explanation: This is an excercise to distinguish between two confusing verbs in Spanish "ser" and "estar". In general, the verb "ser" is used for permanent situations and characteristics. That is why in Question 7 both blanks are filled with "es" (the verb form for the third person singular), as Martin is from Mexico (permanent characteristic) and he is her classmate (a current situation). In the case of Question 2 "ya son las ocho de la noche", it is a fixed expression used to convey surprise. As regards the verb "estar", it is used to indicate position, temporary situations or perceptions. Questions 2, 3. 4, 5, 8 and 9 indicate or ask where some person is (position). They have been conjugated according to the person in the sentence: estás: 2nd person singunlar vos (you), está: 3rd person singular el/ella (he/she), estoy: 1st person singular yo (I), and están: 3rd person singular ellos (they). Finally, Question 1 is a fixed expression "como estás" that means "how are you".
Esta ocupada (she is busy)
