    Which of the following most logically completes the
    argument?
    Ferber’s syndrome, a viral disease that frequently
    affects cattle, is transmitted to these animals through
    infected feed. Even though chickens commercially
    raised for meat are often fed the type of feed
    identifi ed as the source of infection in cattle, Ferber’s
    syndrome is only rarely observed in chickens. This
    fact, however, does not indicate that most chickens
    are immune to the virus that causes Ferber’s
    syndrome, since.....................

    (A) chickens and cattle are not the only kinds of
    farm animal that are typically fed the type of
    feed liable to be contaminated with the virus that
    causes Ferber’s syndrome
    (B) Ferber’s syndrome has been found in animals
    that have not been fed the type of feed liable to
    be contaminated with the virus that can cause
    the disease
    (C) resistance to some infectious organisms such
    as the virus that causes Ferber’s syndrome can
    be acquired by exposure to a closely related
    infectious organism
    (D) chickens and cattle take more than a year to
    show symptoms of Ferber’s syndrome, and
    chickens commercially raised for meat, unlike
    cattle, are generally brought to market during
    the fi rst year of life
    (E) the type of feed liable to be infected with the
    virus that causes Ferber’s syndrome generally
    constitutes a larger proportion of the diet
    of commercially raised chickens than of
    commercially raised cattle


    OA is D ? Need help understanding the answer.

    Help appreciated Smile

    The only option which supports the last line of the parent argument
    "This
    fact, however, does not indicate that most chickens
    are immune to the virus that causes Ferber’s
    syndrome, since..................... "

    is D. It is pretty evident from the options.

    Hope you understand that only D can logically conclude the argument.

    We have to find a reason about why only cattle not chicken (commercially raised for meat) are affected by this disease when both are fed by the same feed.

    Here are our options,

    Quote:
    (A) chickens and cattle are not the only kinds of
    farm animal that are typically fed the type of
    feed liable to be contaminated with the virus that
    causes Ferber’s syndrome
    'are not the only kinds' tries to bring in other types of animals and thus, out of scope since argument talks only about cattle and chicken.

    Quote:
    (B) Ferber’s syndrome has been found in animals
    that have not been fed the type of feed liable to
    be contaminated with the virus that can cause
    the disease
    This option talks about animals contaminated with disease even when they are not fed with the contaminated feed. Thus, out of scope.

    Quote:
    (C) resistance to some infectious organisms such
    as the virus that causes Ferber’s syndrome can
    be acquired by exposure to a closely related
    infectious organism
    This option talks about how resistance can be gained against the virus. Since nothing about resistance is described in argument, this is again out of scope.

    Quote:
    (D) chickens and cattle take more than a year to
    show symptoms of Ferber’s syndrome, and
    chickens commercially raised for meat, unlike
    cattle, are generally brought to market during
    the fi rst year of life
    This talks about the time, which is more than a year, for the virus to become active. Thus, tries to justify why most chickens though fed with infected feed are not infected with the virus. This is because the meat is supplied to market in less than a year (which is less than the time required for the virus to become active). Thus, correct.

    Quote:
    (E) the type of feed liable to be infected with the
    virus that causes Ferber’s syndrome generally
    constitutes a larger proportion of the diet
    of commercially raised chickens than of
    commercially raised cattle
    The argument doesnot show any relation between the quantity of feed consumed and the chances of getting infected by eating the infected feed. Thus, incorrect.

    Hope it helps. Smile
