Question: Emperor Penguins

Comment on Emperor Penguins

I'm not too clear on why B isn't the answer.Where in the passage does it say that age and size have a relationship?

The last sentence says that smaller penguins are typically younger than larger penguins.

Your way of teaching is incredible,using higher level reasoning. Thank you.

Hello Brent,
i dont understand why "Smaller P's Typically younger" is considered to be a premise as the "since" in front of the sentence showcases that it's there to explain why size is not a factor.

I'm not sure why the word "since" diminishes the validity of the premise that smaller penguins are typically younger. Can you elaborate?

what i am saying is the folowing :

SIze is not a Factor Because "Smaller P's typically younger".
It seems to me that the main point here is that size is not a factor ilustrated by the fact that they have different ages.
So how can we give the same weight to
P : SIze is not a factor
P : Smaller P's are typicaly younger.

Therefore i am not clear why B is not the right answer

One of the premises is that smaller penguins are typically younger, and answer choice B says that there's no relationship between size and age.

Here's the basic idea of the passage: Scientists found that most of the dead penguins were large. So, the conclusion was that the larger penguins were more susceptible to dying. However, the author suggests that the larger penguins (which are older) may just be dying from old age.

Ok Thanks
