Apparently someone else had the same question as you. Well since I answered that person’s questions, I hope that the screenshots that I send you are helpful.
1. Juan Carlos y Sofia son de España.
2. Rosa es de Guatemala.
3. Tu eres de Mexico.
4. Orlando es de Cuba.
5. Luz y Marisol son de Colombia.
6. Mercedes y yo somos de Panama.
Estan Caminando isn't the answer as because "estan" implies to be another person, but this isn't the case as it's only the man, the man isn't walking (caminando either)
He isn't shopping (comprando) and he isn't painting (pintando)
The only logical answer is he's cooking (cocinando) which is also heavily implied as him having the bowl and whisk
B.) Esta Cocinando is your answer
1. Yo llegé a mexico en verano. 2. Almorze en un restaurante cerca de la catedral. 3. Luego cruze la avenida para subir al autobus. 4. Page el boleto y fui a chichen itza.
