Answer 1

Resposta:

Did they finish their test?

They didn't finish their test. (pode ser também: They did not finish their test.)

Didn't they finish their test?

Explicação:

lembre que quando usa auxiliar (do/does/did/ etc...) o verbo volta pra forma regular, por isso fica "finish" ao invés de "finshed"
