E9: Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the
questions.
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.
Question 1: The word “substitute” in the passage is closest in meaning to ____.
A. addition
B. alternative
C. imitation
D. solution

C. petrol
D. water
Question 4: The word “vanished” in the passage is opposite in meaning to ____.
A. appeared
B. produced
C. introduced
D. invented
Question 5: It is stated in the passage that water-fuelled cars may contribute to ____.
A. save energy
