All light on the night
Our cities and towns are far from silent at night. As most of ______ are going to bed, a lot of workers are just going to their jobs. It is estimated that up to a fifth of the working population carries out its duties at night - running hospitals and
maintaining power stations, for example.
There is one problem: They have the same biological clock as day workers. Night workers often have trouble sleeping through the day, and sometimes find ______ harder to stay awake, which means mistakes are more likely to happen. Dr Lawrence Smith, a psychologist, [13] discovered that among people who1 do the same job, night workers suffered 20% more injuries than day workers.
He is now testing the theory that the light can be used to fool the human body clock.The body clock appears to be influenced by light, because one chemical at its disposal is sensitive to light.
Adapted from Advance your English
We can replace the pronoun 'who' (ref. 1) by
that.
whose.
which.
whom.
Gabarito:
that.
A) CORRECT: pois o that faz a referenciação à pessoa citada anteriormente da mesma forma que o who, sem mudar seu sentido nem sua sintaxe.
B) INCORRECT: pois o whose é utilizado para pessoas, mas tem o sentido de posse, algo que não está expresso aqui.
C) INCORRECT: pois o uso de which é feito para quando se tem duas ou mais opções, mas nesse caso s edeseja apenas se referenciar a quem já foi citado anteriormente.
D) INCORRECT: pois o whom é utilizado para se referir ao objeto da oração, sendo que, nesse caso, não temos um objeto da oração, mas sim o sujeito.
