Hola, antes de responde tu pregunta quiero explicarte lo siguiente para que te pueda ayudar:
WAS y WERE por el pasado del TO BE (am, is y are)
WAS lo usas con (I, He, She, it)
WERE lo usas con (You, We, They)

Voy a reemplazar los nombres por pronombres para que te sea mas facil entender.

luego de lo dicho te indico las respuestas:

1.the cat  (It ) WAS  In the garden
2.fede and david (they)   WERE . Very sleepy last night
3.my baughter (she)  WAS    Barn in august
4.you   WERE  Very noisy in class yesterday
