▶ Your Answer : While the reading passage provides three
possible solutions to control Cane toads, the lecturer has the opposite point
of view for several reasons.First of all, reading passage points out
that building fences could be a practical and cost-effective way.
However, it encounters the lecturer's claim
that mounting fences simply will not work since cane toads will be still able
to use rivers and streams, which are not available for building fences, as
their migration routes.
Secondly, reading passage claims that recruiting
volunteers would be a solution in sweeping cane toads.
However, it contradicts the lecturer's
claim that it is hard to educate local volunteers since the similarity of cane
toads’ eggs and those of frogs.
Furthermore, if not properly educated, the
volunteers may fail to distinguish eggs of native frogs from cane toads',
resulting in the decrease in the native frog population.
Lastly, reading article argues that the new
virus can make cane toads to be eliminated.
However, it refutes the lecturer's claim
that the new virus will not only decrease the cane toads' population but also
have a possibility in decreasing the native ones. |
