Question

Was/were

Tengo entendido que WAS se emplea para el caso de I, he, she, it y para singular y que para WERE se emplea en you, we, they, plural y casos hipotéticos (Subjuntivos). Pero tengo confusión con unas oraciones D:

Henry and Todd was / were very absent-minded yesterday. (Tengo entendido que va WERE pero no entiendo muy bien el por qué)
13. Pat and Samantha was / were very busy.

Y bueno tengo dudas también en:
8. This was / were a very mild Summer.
9. These was / were my toys.
11. My parents was / were very sad yesterday.
(En una página vi que algunas estaban de diferente forma a como yo creo que es, de allí mi confusión)
7. My aunt Lucy .............. at the shopping centre last night.
8. Uncle Thomas ................ at home the whole weekend.
10. My family ............. in Madrid on holidays last Summer.
14. That was / were my sisters’ favourite doll.
15. Those was / were Ann’s best friends.


MUCHAS GRACIAS!!

Answer 1

Creo que tenes el mismo problema en todas. En las que tenes dos o mas personas (como "Henry and Todd" o "My parents"), es un plural, es como si dijera "They". Por ende, va were.
This es en singular, por lo que va was. These es plural, por lo que va were.
Basicamente te tenes que fijar de quién o quiénes estás hablando.
No te las quiero resolver así practicas.
