a) my grandparents wrote a book by ____________​

Answer 1

My grandparents wrote a book by themselves.

Answer 2

Resposta:

themselves

Explicação:

Os pronomes reflexivos em inglês são

myself - I

yourself - you

himself - he

herself - she

itself - it

ourselves - we

yourselves - you (plural)

themselves - they

Quando precedidos por by, os pronomes ganham um sentido novo, tendo o sentido de "sozinho, sozinha".

então o pronome reflexivo deles seria themselves

R: by themselves
