Read the following passages and make an inference about the character’s feelings. Explain how you arrived at this inference.
Question: 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 identified as the source of infection in cattle, Ferber's syndrome is only rarely observed in chickens.
It can be inferred from the statement that the fact in the last sentence does not indicate that most chickens are immune to the virus that causes Ferber's syndrome because?
1
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
2
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.
3
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.
4
Chickens and cattle take more than a year to show symptoms of Ferber's syndrome and chickens are commercially raised for meat, unlike cattle, are generally brought to market during the first year of life
