Short Answer Questions (30-40 words)

Answer: Ebright tried to find the cause of a viral disease that killed monarch caterpillars every few years. He thought disease may be caused by beetles. He tried to raise caterpillars in the presence of beetles. He did not get any result but he showed his experiment.

He won a prize.




Answer: According to Weinherer, Ebright always used to put in extra efforts for every activity. Ebright was competitive. He was not interested in winning for the sake of winning or winning to get a prize. He was winning because he wanted to do the best. For right reasons he wanted to be the best.

Answer: In an experiment Ebright had defined the purpose of twelve tiny golden spots on the wings of monarch pupa. He showed that these spots secrete a hormone necessary for development of pupa into an adult butterfly.

He won first prize for this project.




Answer: His mother took Ebright to  several places, bought him telescope, microscope and other equipments. She ensured good company to him. She always kept him busy. She bought a book ‘The Travels of Monarch X’ for Ebright, which proved to be a turning point in his life.

Answer: In addition to collecting butterflies, he used to collect rocks, fossils and coins. He became an eager astronomer. He used to gaze at start all night.




Answer: Ebright realised that by chasing butterflies, one would not catch many butterflies. So he would catch a female monarch, take her eggs and raise them in his basement through their life cycle. Now he had many butterflies to tag.

Answer: Viceroys try to copy monarchs because birds do not like to eat monarchs. In order to save their own life, viceroy try to copy monarch.

Answer: Ebright showed that the golden spots produce a hormone necessary for the full development of butterfly. He grew a cell from a monarch’s wing in culture and showed that the cells would divide and develop only if they were fed the hormones from the golden spots.

Answer: When Ebright was looking at the X-ray photo of chemical structure of hormone, he got new idea about cell life. Combined with the finding of insect hormone, he now found out how cell can read blueprint of DNA.

Answer: Dr Urquhart was a scientist in Canada. He was doing experiments on butterflies.

Ebright had started tagging butterflies after reading a book. In his first science fair, he understood that he had to do some experiments to win a prize. He wrote to Dr. Urquhart to suggest some ideas for doing experiments.

Answer: Ebright had tagged a large number butterflies to study their migration. But information about only two of them was received. These were not more than seventy five miles from his home.

So he lost the interest.

Long Answer questions (120-150 words)

Answer: Success never comes straight at the first instance. Through dedication and constantly learning, failure can be turned into success.

Ebright started his journey by collecting butterflies. Then he moved on to tagging these. When he did not find enough butterflies he started raising these in his basements.

In his first attempt at the science fair he did not win any prize. He understood that it was necessary to conduct experiments and show it to the world.

He requested help of Dr. Urquhart to obtain ideas about experiments. During those experiments he found that viceroys tried to copy monarch to avoid being prey to birds. This time he won a prize.

He later conducted series of experiments about twelve gold spots on wings of monarch. Eventually this led to a remarkable discovery how a cell communicates with DNA.

Thus we infer that Ebright faced failure many times in his life. But every time he turned it into a success through dedication.

Answer: During his early childhood Ebright had started collecting butterflies. He also collected rocks, fossils and coins. He was an eager astronomer. Sometimes he spent the full night gazing at stars.

During his high school he started participating in debating and Model United Nations clubs. He became a champion debater and an excellent public speaker. His teacher of social studies Mr Weiherer was the advisor to both the clubs.

Weiherer had written that Richard always gave extra efforts. He was not interested in the winning for the sake of winning. He was winning because he wanted to do everything in the best possible way.

Ebright was an expert photographer particularly of nature and scientific exhibits. He was a good canoeist. Actually Ebright was a perfect outdoor person.

We can infer that Ebright had several interest besides his scientific research.
