Q6.A · 5 marks · Reading comprehensionCompetency-basedThe Making of a Scientist

Read the given extracts and answer the questions for ANY ONE of the two, given.

The question he tried to answer was simple: What is the purpose of the twelve tiny gold spots on a monarch pupa?
"Everyone assumed the spots were just ornamental," Ebright said.
"But Dr Urquhart didn't believe it."

To find the answer, Ebright and another excellent science student first had to build a device that showed that the spots were producing a hormone necessary for the butterfly's full development. This project won Ebright first place in the county fair and entry into the International Science and Engineering Fair. There he won third place for zoology. He also got a chance to work during the summer at the entomology laboratory of the Walter Reed Army Institute of Research.

(The Making of a Scientist)

  1. i

    State any one inference about Dr Urquhart from the given context:
    Everyone assumed the spots were just ornamental," Ebright said. "But Dr Urquhart didn't believe it."

    1 mark
  2. ii

    State TRUE or FALSE.

    None of the terms (a) -(d) below, can be applied to the question - What is the purpose of the twelve tiny gold spots on a monarch pupa?
    (a) A hypothesis - a proposed explanation for a phenomenon
    (b) An assumption - something that is taken for granted or assumed to be true without proof
    (c) A premise - a proposition that forms the basis of an argument
    (d) A theory - a well-substantiated explanation for a natural phenomenon

    1 mark
  3. iii

    Ebright's approach towards finding the purpose of the gold spots on a monarch pupa was highly effective. Elaborate in about 40 words, with reference to the extract.

Hints

Open one hint at a time and try again before the next.

Hint 1

For (i), think about what it means to disbelieve what everyone assumes.

Hint 2

For (ii), the sentence is a question, not a claim.

Hint 3

For (iii), name what he built, what it showed, and the rewards he got.

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. (i) Dr Urquhart questioned accepted assumptions and was curious and open-minded about other explanations. (Any one.)

    1 mark

  2. (ii) TRUE. The question is only a statement of what Ebright wanted to find out, so it is not a hypothesis, assumption, premise or theory.

    1 mark

  3. (iii) Ebright's approach was effective because he built a device showing that the spots produce a hormone needed for the butterfly's full development. This disproved the belief that they were only ornamental and won him a county fair prize, a place at the International Science Fair and a summer lab opportunity.

    2 marks

  4. (iv) 'An opportunity'.

    1 mark

Answer: (i) Dr Urquhart was curious and questioned assumptions; (ii) TRUE; (iii) the device proved the spots produce a hormone, which earned him awards and lab work; (iv) an opportunity

Where the marks are

  • (i) One valid inference (1 mark)
  • (ii) TRUE (1 mark)
  • (iii) Evidence of effectiveness from the extract, specific points (2 marks)
  • (iv) an opportunity (1 mark)
