Your answer​

Answer 1

Answer:

Ebright thought that the disease was being transmitted through beetles so, he started raising caterpillars in the presence of beetles. It was of no use but when he showed that he had tried such an experiment, he won something for his project. For the next year, he tried the theory that viceroy butterflies copy monarchs.
