Researcher: Dinosaurs lack turbinates—nasal cavity bone structures in warm-blooded species that minimize water loss during breathing. █████████ ██ ████ ████████████████ ████ ███████ ████ ███ █████████ ████ █████████████ █████ ███████████████ ████ ██ █████████ ████████ ███ ██████ ███████ ████ ████ ████ ████████ ███████ █████ ██ █████████ ███ ███████ █████ ████████████ ████ █████ █████████ ████ ████████████ ███████ █████ ███████ ████ █████████████
Summarize Argument: Counter-Position
The author rejects the paleobiologists’ belief that all dinosaurs were cold-blooded. Since some dinosaurs lived in places where only warm-blooded animals could survive, the author implies that some dinosaurs must have been warm-blooded.
Identify Argument Part
It’s a premise. The author uses the claim that only warm-blooded animals could survive in those areas to prove that the dinosaurs that lived in those areas were not cold-blooded.

a
It is presented ██ █ █████████ ██████████████ ██ ███ ██████████ ████ ███████████
The last sentence supports the conclusion, so it can’t be a counter-example to it.
b
It is a ███████ ███████ ██ ███████ ██ ███ ██████████ ████ ███████████
This accurately describes the role of the last sentence. It’s a premise supporting the author’s conclusion.
c
It is presented ██ ███████████████ ██ ███ ████████████████ █████████ ████ █████████ ████ ███████████
The author never suggests that dinosaurs actually have turbinates. The claim that the author counters is the paleobiologists’ claim that all dinosaurs were cold-blooded.
d
It is the ██████████ ████ ███████████
The main conclusion is the claim that the paleobiologists are wrong. The last sentence supports that conclusion.
e
It is an ████████████ ██████████ ███ █████ ███ █████ ████ ████ ████████ ███████ █████ ██ █████████ ███ ██████ ██ ███████ ██ ████████
The claim that some dinosaurs lived in Australia and Alaska isn’t offered to help prove that only warm-blooded animals can live in freezing temperatures.
