▶ Your Answer :
The reading passage contends that the role
of Lambeosaurus crest can be fully explained by three theories. On the other
hand, the lecturer brings up several points that contradict these theories this argument.
First, the reading passage states that the crests
were used to appeal to mates. However, the lecturer rebuts the reading passage’s
assertion by saying that most reptiles depend on behavior and sound rather than their crests
to attract the mates. To be specific, a Lambeosaurus would have lifted its head into
the air and made noise such in order to appeal to the opposite gender. This
implies that it is unlikely that the crests would have been used to obtain
mates.
Second, the reading passage explains that
the crests would have been used for combat. However, the lecturer thinks that
it<(what is it?) is not enough to prove it. This is because the crest is pointed backwards instead of forward, thus, it could not have functioned as protective helmets. Also,
the crests were was hollow inside, which means that it was too fragile to attack other
members of dinosaurs.
Third, the reading passage contends that
the function of the crests was to supply air while Lambeosaurus held its head
underwater to eat. However, the lecturer is in the opposition of this in the idea. The
lecturer claims that because Lambeosaurus were massive dinosaurs, they needed a
lot of oxygen. However, because the crests were so small compared to the body, they
could not have supplied enough oxygen to the Lambeosaurus’s body efficiently. Also,
Lambeosaurus would have kept keep their head underwater by deep breathing.
