B. The Strange Case of BeriBeri In 1887 a strange nerve disease attacked the people in the Dutch East Indies. The disease was BeriBeri. Symptoms of the disease included weakness and loss of appetite. Victims often died of heart failure. Scientists thought the disease might be caused by bacteria. They injected chickens with bacteria from the blood of patients with BeriBeri. The injected chickens became sick. However, so did a group of chickens that were not injected with bacteria from the blood of patients with BeriBeri. One of the scientists, Dr. Eijkman, noticed something. Before the experiment, all the chickens had eaten whole-grain rice, but during the experiment, the chickens were fed polished rice. Dr. Eijkman rescarched this interesting case. he found that polished rice lacked thiamine, a vitamin necessary for good health. 1. State the Problem. 2. What was the hypothesis? 3. How was the hypothesis tested?

![B. The Strange Case of BeriBeri
In 1887 a strange nerve disease attacked the people in the Dutch East Indies. The disease was
BeriBeri. Symptoms of the disease included weakness and loss of appetite. Victims often died of heart
failure. Scientists thought the disease might be caused by bacteria. They injected chickens with
bacteria from the blood of patients with BeriBeri. The injected chickens became sick. However, so did
a group of chickens that were not injected with bacteria from the blood of patients with BeriBeri. One
of the scientists, Dr. Eijkman, noticed something. Before the experiment, all the chickens had eaten
whole-grain rice, but during the experiment, the chickens were fed polished rice. Dr. Eijkman
researched this interesting case. he found that polished rice lacked thiamine, a vitamin necessary for
good health.
1. State the Problem.
2. What was the hypothesis?
3. How was the hypothesis tested?
4. Should the hypothesis be supported or rejected based on the experiment?
5. If it will be rejected, what should be the new hypothesis? The new hypothesis would be that the
lack of thiamine in the chick](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F71a1980b-262d-4b3f-b97e-d65a56cebc9b%2Fd9c5dd9b-4f72-4ccc-8687-7bdff581d8a2%2Fdlqcj6g_processed.png&w=3840&q=75)
