I have two arguments against "A", the first more serious

A agrees with the passage. The passage states "The bones had NEARLY the same body temperature in their limbs" Answer choice A writes that the core body temperature of warm-blooded animals is slightly higher, so these bones found very well may be from a warm-blooded animal, it does not weaken

Also what you said, we don't know anything about "large warm-blooded", these bones may be smaller animals, and answer choice A would not weaken either.


Are either of these the correct way to knowck out A? had a tougher time with this answer choice

Those are two very good reasons for eliminating that answer, sammydz! Great work!
