▶ Your Answer :
<Lambeosaurus>
The lecturer argues that the possible
function of crests do not matched with what we know.
This contradicts the reading passage’s
claim that possible uses have been identified.
To begin with, the lecturer contends that attracting
opposite sex is extremely doubtful.
Because animals mostly appeal to other mates
by using their behaviors and sounds, not appearances. For example, crocodiles
use noises to attract opposite sex.
This cast doubt on the reading passage’s
claim that lambeosaurus use their crest to appeal to mates.
On top of that, The lecturer argues that
crest is not appropriate gear to fight.
Actually, Crest is in the backwards of head,
So it is not proper battle tool. This crests are also hollow , which means it
is too fragile to use for defending or fighting.
This counter the reading passage’s claim
that lambeosaurus fight with other creature by using crests.
Finally, They can’t provide air.
Compared to its body, Crests are very small
to provide air to lambeosaurus.
The idea that lambeosaurus used their
crests to breathe when they submerged is logically wrong
This refutes the reading passage’s claim
that they supply air while dinosaurs eat plants in the water.
