VR4-4

civilians.

through a remote camera.

unethical.
B Injury to civilians is an ethical
consequence of warfare.
C Acts of war are always
unethical.
D Drone attacks can have
unethical consequences.
A humans will always fight one another.
B there were no humanitarian conventions before 1949.
C there is no justification for the con ict in Afghanistan.
D civilians in civil wars have no legal rights.
VR4-3 According to the passage, the writer most probably agrees that:
A the Geneva Conventions are
ineffective.
B the mass bombing of cities
in wartime is an international
crime.
C there will be fewer wars in the
future.
D developments in technology
will prevent wars.

Verbal Reasoning
VR5 – Greener Jet Engines
The recent decision by the European Parliament to include air traffic in the EU’s Emissions Trading Scheme (ETS) has increased the pressure on aircraft manufacturers to produce ‘greener’ aircraft. An estimated 3% of Europe’s entire greenhouse gas emissions are currently generated by airlines, and with it potentially doubling by 2020 the introduction of this controversial tariff has increased the pace of innovation. There are two areas of potential fuel saving in aircraft design – the engines and the airframe. The ratio of lightweight materials and recycled components in wing and body production is growing, but creating an engine that reduces fuel consumption, noise and nitrous oxide pollution is key.
In normal turbofan designs, an intake fan at the front reduces the speed of air passing around the engine, mixing it with the much faster moving hot gases generated by burning fuel and air to create greater thrust. This
calls for larger engine chambers which can allow this slowed air to pass through but the bigger the engine, the greater the weight, fuel consumption and noise. An American company, Pratt and Whitney, have developed such an engine by introducing a geared turbofan to their designs. This is based on the principle that turbines are most effective at high speeds and fans at much lower revolutions.
