It is believed that keeping poultry in brightly lit cages significantly increases the amount of head-pecking among them. However, in recent experiments, commercially reared chickens when kept in brightly lit cages were found to behave much less aggressively; instead, they indulged in an almost “sleepy” behavior – they tended to mostly put their heads between their wings and seemed to doze off, an action unusual for such chickens. This raises serious questions on the belief that the visibility accorded by the bright lights is majorly responsible for the increased display of head pecking among the poultry.
Which of the following, if true, most seriously weakens the argument?
  • a)
    The pecking order is established early in a chicken's life when raised in a flock; the young chicks peck each other and bully one another when they are around food.
  • b)
    Head-pecking, is almost always the result of high stress levels and when that happens, the birds will sometimes pluck each other’s feathers out, and can really hurt one another.
  • c)
    Commercially reared chicken when put in cages are often equipped with blinding glasses that prevent more than 90% of the light from entering the retina.
  • d)
    While Commercially reared chicken in the experiment exhibited a docile behaviour in cages, they were much more aggressive a few hours later when allowed to roam freely on the farm.
  • e)
    While most chicken in the experiment exhibited a docile behaviour when in cages, a few were unusually aggressive.
Correct answer is option 'C'. Can you explain this answer?

Argument summary:
The argument presents a contradiction between the belief that brightly lit cages increase head-pecking among poultry and the results of recent experiments, where commercially reared chickens in brightly lit cages exhibited sleepy behavior instead of increased aggression. The argument suggests that this challenges the belief that visibility due to bright lights is the main cause of head pecking.
We need to find the option that weakens this argument by providing an alternative explanation or a factor that could explain the observed behavior of the commercially reared chickens.
(A) This option provides information about the pecking order and aggressive behavior among young chicks. However, it does not directly address the behavior of commercially reared chickens in brightly lit cages. It does not weaken the argument.
(B) This option explains that head-pecking is the result of high stress levels and can cause harm to chickens. However, it does not provide an alternative explanation for the behavior of commercially reared chickens in brightly lit cages. It does not weaken the argument.
(C) This option states that commercially reared chickens in cages are equipped with blinding glasses that prevent most light from entering their retinas. This information weakens the argument by suggesting an alternative reason for the observed behavior. The lack of visibility due to the blinding glasses could explain why the chickens exhibited sleepy behavior instead of aggression. This option weakens the argument and is the correct answer.
(D) This option introduces a new factor where the commercially reared chickens were more aggressive when allowed to roam freely on the farm. However, this information does not directly relate to their behavior in brightly lit cages. It does not weaken the argument.
(E) This option states that a few chickens exhibited unusually aggressive behavior. However, it does not provide an alternative explanation for the majority of the chickens exhibiting sleepy behavior. It does not weaken the argument.
In conclusion, option C weakens the argument by providing an alternative explanation for the observed behavior of commercially reared chickens in brightly lit cages. The presence of blinding glasses suggests that visibility may not be the primary factor causing aggression or head-pecking.
