‘Noah's Ark’ seed vault chalks up a million crop varieties
A special vault storing the world's most precious seeds has now amassed over one million different plant varieties. It recently took delivery of a consignment of seeds from 70,000 different crops. Global Seed Vault is buried deep in an icy mountain in the Arctic Circle area of Svalbard, Norway. It was started ten years ago to safeguard the future of the world's food supply. Climate change is causing more and more droughts around the world, which are threatening different species of plants. The vault holds back-ups of seed samples stored in other seed banks around the world. Hannes Dempewolf, a senior scientist at the Crop Trust, said: “Hitting the million mark is really significant.” Workers at the vault were not sure they would reach the million mark so soon. The crisis in Syria meant there was a shortfall of 90,000 seeds at the vault. The latest delivery to the vault included cereal staples. There were also more unusual crops like the onion potato from Estonia and the Bambara groundnut, which is being developed as a drought tolerant crop in Africa. Marie Haga, executive director of the Crop Trust, spoke about the importance of the vault. She said: “Safeguarding such a huge range of seeds means scientists will have the best chance of developing nutritious and climate-resilient crops that can ensure future generations don't just survive, but thrive.”

Which alternative is grammatically correct according to the Passive Voice?
The Gilmours have bought a new house in Iceland.
A new house has bought by the Gilmours in Iceland.
A new house has being bought by them in Iceland.
A new house has been buying by the Gilmours in Iceland.
A new house has been bought by them in Iceland.
Gabarito:
A new house has been bought by them in Iceland.
A) INCORRECT: pois nessa sentença não houve uma mudança expressiva para o past participle para estar na voz passiva. Pelo contrário, foi usado o mesmo verbo no mesmo tempo que do enunciado, mudando apenas o sujeito.
B) INCORRECT: pois nessa expressão, o uso de "being" indica uma ação que está acontecendo no presente, o que é inválido para a passive voice.
C) INCORRECT: pois mesmo que o "been" indica a ideia do past participle, o uso de buying expressa uma ideia de presente ainda acontencendo, o que não é possível para a voz passiva.
D) CORRECT: pois, nesse caso, o verbo foi corretamente colocado no past participle com as mudanças em relação ao verbo do enunciado, adicionando o "been" e mantendo o verbo no passado, fazendo as devidas substituições do verbo auxiliar (has) em detrimento do sujeito.
