Direction: “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.Q. Choose the option that is true for the two statements given about the information in the extract: Statement 1- Starling feeds on Viceroys.Statement 2- Starling does not eat Seeds and Insects.- a)Both statements are clearly mentioned in the extract.
- b)Statement 1 cannot be clearly inferred from the Text and statement 2 is true.
- c)Statement 1 is false and statement 2 cannot be clearly inferred from the Extract.
- d)Both statements need to be inferred from the given Extract.
Correct answer is option 'C'. Can you explain this answer?

Starling likes to eat Monarchs and not Viceroys. What the author means by ordinary Bird food is not clarified in the passage, so Statement 2 cannot be inferred from the extract.

Direction: 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.Q. 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.

Understanding Ebright's Reaction
Ebright’s subdued reaction to his discovery is intriguing, and option 'B' best captures the essence of his achievement. Here’s a detailed explanation of why this option is the most appropriate:
Discovery of New Knowledge
- Ebright was on the brink of uncovering a significant biological concept.
- His findings, combined with the photos he analyzed, provided a key insight into how cells interpret their DNA blueprint.
The Meaning of 'Eureka'
- The term 'Eureka!' is often associated with sudden realizations or important discoveries.
- It signifies a moment of triumph when someone finds the solution to a complex problem.
Why 'B' is Correct
- Ebright's work was groundbreaking, as it contributed to understanding a fundamental biological process.
- His realization was a significant intellectual leap, warranting a celebratory cry like 'Eureka!'.
Comparison with Other Options
- Option 'A': While collaboration is important, Ebright's primary achievement was the discovery itself, not the need for a partner.
- Option 'C': Relief from hard work does not align with the excitement that comes with a major discovery.
- Option 'D': While he valued his teachers' influence, the essence of his reaction stemmed from the new knowledge he was uncovering.
Conclusion
- Ebright's journey represents the spirit of scientific inquiry.
- His subdued response highlights that true discoveries often evoke a deep sense of understanding rather than mere excitement.
- Hence, option 'B' encapsulates the essence of his experience perfectly.
