Question 1-5:

2. NO (para 2, first 3 lines: “More than 4,000 species of these remarkable creatures have
evolved and adapted to the world’s different climates and the dung of its many animals.

3. YES (para 3, line 2-7: “at the Australian Government’s premier research organisation, the
Commonwealth Scientific and Industrial Research Organisation (CSIRO), suggested that
dung beetles should be introduced to Australia to control dung-breeding flies. Between
1968 and 1982, the CSIRO imported insects from about 50 different species of dung
beetle, from Asia, Europe and Africa, aiming to match them to different”)

4. YES (para 2, last 3 lines: “climatic zones in Australia. Of the 26 species that are known
to have become successfully integrated into the local environment, only one, an African
species released in northern Australia, has reached its natural boundary”)

5. NO (para 3, last 5 lines: “beetles are released, a handful at a time, into fresh cow pats in
the cow pasture. The beetles immediately disappear beneath the pats digging and
tunneling and, if they successfully adapt to their new environment, soon become a
permanent, self- sustaining part of the local ecology. In time they multiply and within
three or four years the benefits to the pasture are obvious”)

Question 6-8:
6. South Africa

7. French

8. Spanish(para 5, line 3-9: “directly underneath the pats, which are hollowed out from within.
Some large species originating from France excavate tunnels to a depth of approximately

tunnels. The shallowest tunnels belong to a much smaller Spanish species that buries
dung in chambers that hang like fruit from the branches of a pear tree. South African
beetles dig narrow tunnels of approximately 20 cm below the surface of the pat. Some
surface-dwelling beetles, including a South African species, cut perfectly”)

Question 9-13:
9. „temperature‟ (para 6, line 3-4: “state of Victoria, the large French species (2.5 cms long)
is matched with smaller (half this size), temperate-climate Spanish species. The former
are slow to recover from”)

10. „early spring‟
11. „2-5‟(para 6, line 6-7: “spring until autumn. The latter, which multiply rapidly in early spring,
produce two to five generations annually. The South African ball-rolling species, being a

12. „sub-tropical‟

13. South Africa tunneling
(para 6, last 4 lines: “to five generations annually. The South African ball-rolling species,
being a sub- tropical beetle, prefers the climate of northern and coastal New South Wales
where it commonly works with the South African tunnelling species. In warmer climates,
many species are active for longer periods of the year”)
