To answer these questions you should have read the background text "Aviation" very well.
You may need a sheet of paper and a pencil. A calculator would be helpful.

Find the right answers!

1) Above Ireland in May 1992 there was per grid area of 1 x 1 degree a daily combustion of fuel by civil aircrafts of a magnitude of:
a) 1 - 10 kg.
b) 100 - 1 000 kg.
c) 10 000 - 100 000 kg.
d) 1 000 000 - 10 000 000 kg.

2) The unit tonne-kilometre is a:
a) measure of the fuel consumption of aircrafts.
b) measure of the total cargo transported by aircrafts including
        passengers.
c) measure of the total cargo transported by aircrafts excluding
        passengers.
d) measure of volumetric capacity of the complete air traffic.

3) Given a world population of 5.7 billion in 1995, every human being flew an
        average of:
a) 125 km by plane.
b) 235 km by plane.
c) 445 km by plane.
d) 655 km by plane.

4) Which kind of clouds forms as a result from air traffic in or close to the
        tropopause?
a) altostratus cloud
b) stratus cloud
c) cumulus cloud
d) cirrus cloud

5) One part of the exhaust gases of aircrafts contributes to the
        diminuation of the greenhouse effect.
a) carbon dioxide
b) sulphate
c) water
d) exhaust soot

6) A future consequence could be that the effect mentioned in question
        no.5 will be reversed because
a) this substance contributes to the formation of cirrus clouds that have
        a positive greenhouse effect.
b) under the influence of light this substance breaks down into
        constituents that have a positive greenhouse effect.
c) this substance reflects the infrared radiation of the earth back to the
        earth.
d) this substance promotes the growth of plants on soils with a high lime
        component.

7) Prognoses for the future concerning the effect of air traffic on the
        climate can be made:
a) very precisely, because all effects of all substances in this complex
        contaxts are well-known. The future development of the earth
        population is also well-known.
b) with only one uncertainty. Scientists could clear up most
        interrelationships. Only the future development of the earth
        population is not well-known.
c) with a few uncertainties, because not even the future
        development of the earth population and the effect of cirrus clouds
        are known today.
d) presently very vaguely, because only very few aspects of the
        complex interrelationships have been thoroughly investigated
        and are predictable.
