CBSE Class 10 English The Making of a Scientist MCQs Set B

(A) When he saw those photos, Ebright didn’t shout, ‘Eureka!’ or even, ‘I’ve got it!’ But he believed that, along with his findings about insect hormones, the photos gave him the answer to one of biology’s puzzles: how the cell can ‘read’ the blueprint of its DNA. DNA is the substance in the nucleus of a cell that controls heredity. It determines the form and function of the cell. Thus, DNA is the blueprint for life. Ebright and his college room-mate, James R. Wong, worked all that night drawing pictures and constructing plastic models of molecules to show how it could happen. Together they later wrote the paper that explained the theory.

Question. Ebright was perhaps expected to shout ‘Eureka!’ because he had
a) realised that he needed a partner to work with to finalise his findings.
b) discovered something new and ‘Eureka!’ was a cry to announce it.
c) worked hard and was relieved at nearing the end of his project.
d) given shape to the teachings of his teachers by choosing this field of science.

Answer: B

Answer: D

(B) “I didn’t get any real results,” he said. “But I went ahead and showed that I had tried the experiment. This time I won.” The next year his science fair project was testing the theory that viceroy butterflies copy monarchs. The theory was that viceroys look like monarchs because monarchs don’t taste good to birds. Viceroys, on the other hand, do taste good to birds. So, the more they look like monarchs, the less likely they are to become a bird’s dinner. Ebright’s project was to see whether, in fact, birds would eat monarchs. He found that a starling would not eat ordinary bird food. It would eat all the monarchs it could get.
