<s>[INST] A fictitious brand of crayons, called "ColourMagic", is manufactured by a company that makes claims about its unique properties. According to the company, ColourMagic crayons contain microscopic, shimmering particles that give colours a more vibrant appearance and make them last longer. The manufacturer also claims that ColourMagic crayons are more resistant to fading due to exposure to sunlight and are easier to colour with because they apply more smoothly. If ColourMagic crayons are truly unique and different from other crayons, we can expect to see something that distinguishes them from other crayons. However, if ColourMagic crayons are like all other crayons, we would expect them to behave in a similar way to other crayons.

Suppose we were to design an experiment to test the claims made by the manufacturer of ColourMagic crayons about their unique properties. Here are a few potential experimental design options:

A) Take a sheet of paper and divide it into three sections. Colour one section with a ColourMagic crayon, one section with a different brand of crayon, and leave the third section blank. Place the paper in a sunny windowsill for 6 months, then compare the colours in the three sections.

B) Take two sheets of paper. Colour one sheet with a ColourMagic crayon and the other sheet with a different brand of crayon. Use a special light meter to measure the intensity of the colours immediately after colouring and again after 6 months.

C) Take two sheets of paper, one made of regular paper and one made of glossy paper. Colour one sheet with a ColourMagic crayon and the other sheet with a different brand of crayon. Ask a panel of volunteers to rate the smoothness of application and the vibrancy of the colours.

D) Take two sheets of paper. Colour one sheet with a ColourMagic crayon and the other sheet with a different brand of crayon. Use a special instrument to measure the microscopic particles in each crayon.

Each of the experimental design options has its strengths and weaknesses. Which option is most likely to provide evidence for or against the claims made by the manufacturer of ColourMagic crayons about their unique properties?[/INST]
