THE VANISHING INVENTION
In 1998, a Valencian professor made an amazing claim. Professor Antonio Cervilla discovered how to use water as a
substitute for petrol. The scientist said that you could drive from Bilbao to Valencia on just half a litre of water His invention
uses a molybdenum compound to break down water into hydrogen and oxygen. Unlike other methods,no electricity is required
and the reaction happens at atmospheric temperature. This impressive technology is based on the way plant enzymes break down
water. The use of molybdenum is the perfect choice because, although rare, it is cheap and found all around the planet.
Since the claims were made nothing more has been heard about this fabulous technology. There is no explanation for the
disappearance anywhere on the internet, apart from a list of similar inventions which have also vanished . An inventor from the
Philipines called Daniel Dingel developed a water -fuelled car but was arrested and sentenced to 20 years in prison. If this
technology were to become widely available, it would prove disastrous for petrol station owners and would also save the planet
from the impending environmental catastrophes being caused by pollution.

1. Từ "substitute" trong đoạn văn có nghĩa gần nhất với "alternative" (thay thế).<br />2. Cervilla's invention không sử dụng enzyme để phân giải nước, vì vậy đáp án là "It uses enzymes to break down water."<br />3. Từ "it" trong đoạn văn đề cập đến "petrol".<br />4. Từ "vanished" trong đoạn văn có nghĩa đối lập với "appeared" (xuất hiện).<br />5. Đoạn văn nói rằng xe chạy bằng nước có thể góp phần cứu môi trường, vì vậy đáp án là "save environment".
