Answer 2

a)No, They weren't (Because Batman was created in 1939 and The Bat-signal didn't appear until Detective Comics #60 in 1942. The Batcave didn't appear until 1948.)

b)Yes, it was (Because who gave The shield was Tony Stark's Father, you can watch The Captain America: The first Avenger movie.)

c)Before Was/were (Em português: Nós não usamos antes(Before) de was, por que o verbo to be é sempre depois do was, por ex: (I was tired yesterday) não ( I tired was yesterday)

d)Before the subject (Em português: Nós usamos o sujeito Eu depois do Was/were, por ex:(Was I sleeping early?).
