Why I believe B is wrong.
No where does it say in the passage that it is impossible to figure out whether the chicken has the disease before it shows symptoms. There may be tests they COULD run, even before the chicken shows symptoms, that would show the chicken has the disease. We just are not told anything about this.
However, since commercial chicken populations are brought to market BEFORE the symptoms show up——(symptoms show up > 1 year and the chickens are brought to market in 1 year or less)——
What C says must be True. A chicken can have the disease, be brought to market before showing any symptoms, and no one would be able to tell.
This is why a failure to observe the symptoms in commercial chickens is NOT good evidence that these chicken are immune. Maybe the chickens have the disease but it’s BEFORE the time when the symptoms start to show. After all, we are told that chickens are brought to market before any symptoms have a chance to appear.
I’ll admit it isn’t the best written passage and there are a few holes....but C is more strongly supported by the Facts.

Hi
Fdambro294 ,
My thoughts on between B and C, since these two are close calls.
As you rightly mentioned, in B there can be ways to find the disease in the chicken. So it's not necessarily true.
But as far as C is concerned I agree with
Vinodsai1995 there is no mention of immunity in the stimulus. So for C to be absolute correct it should mention "more immune than cows" in it IMO.
Experts, what do you think.?

Hello,
Nups1324 and
Fdambro294. The language of the two answer choices in question offers insights into why one answer is overreaching and the other is not. Also, note that despite the
Must be True tag, the question itself states
most strongly supported. This is a difference worth considering. A must-be-true answer
cannot deviate from what the passage lays out; a most-strongly-supported answer merely needs to be the most logical endpoint—among the five answer choices provided—of the information presented in the passage. With that said, how about we take a closer look, with a focus on the two answers in question?

Lofgren's disease has been observed frequently in commercially raised cattle but very rarely in chickens. Both cattle and chickens raised for meat are often fed the type of feed that transmits the virus that causes the disease. Animals infected with the virus take more than a year to develop symptoms of Lofgren's disease, however, and chickens commercially raised for meat, unlike cattle, are generally brought to market during their first year of life.
Which of the following is most strongly supported by the information provided?
B. There is no way to determine whether a chicken is infected with the Lofgren's disease virus before the chicken shows symptoms of the disease.
C. A failure to observe Lofgren's disease in commercial chicken populations is not good evidence that chickens are immune to the virus that causes this disease.
What has been discussed above about (B) is accurate. For all we know, there could exist some sort of blood test or just about any other way for scientists or even farmers to be able to determine that a chicken was infected with Lofgren's disease. The passage provides no insight into the matter. The definitive
is no way is too strong. Meanwhile, choice (C) touches on a notion that
is supported by the passage, namely that chickens can be
infected with the virus, since
Lofgren's disease has been observed, albeit
very rarely, in chickens. The passage even goes out of its way to posit why the disease may have only rarely been observed in chickens, since these animals are
generally killed within
their first year of life, and symptoms take
more than a year to present. We can conclude, therefore, that chickens are not immune to the virus, and also that not observing symptoms of Lofgren's in chickens is not proof that the chickens do not have the disease. In other words, choice (C) is
most strongly supported by the information provided, and that is all we are looking to do.
I hope that helps. Trust the
exact phrasing of the question stem in approaching a CR question. Thank you for thinking to bring me into the dialogue.
