Ans: The emulsion test
Ques: Context: The emulsion test is a method to determine the presence of lipids using wet chemistry. The procedure is for the sample to be suspended in ethanol, allowing lipids present to dissolve (lipids are soluble in alcohols). The liquid (alcohol with dissolved fat) is then decanted into water. Since lipids do not dissolve in water, when the ethanol is diluted, it falls out of solution to give a cloudy white emulsion.

Question: what do you use to test for lipids?
CoT: To answer this question, we should know that: The emulsion test is a method to determine the presence of lipids using wet chemistry.

CoT: This is the relevant information: Until the middle of the 20th century the paint used for the outer coating could contain high concentrations of lead, and this could be ingested when the pencil was sucked or chewed.

Answer: the maximum aperture diameter , or minimum f - number , of a photographic lens. Now, what could be the question and solution-maybe?
Ques: Lens speed refers to the maximum aperture diameter, or minimum f-number, of a photographic lens. A lens with a larger maximum aperture (that is, a smaller minimum f-number) is called a "fast lens" because it can achieve the same exposure with a faster shutter speed. Conversely, a smaller maximum aperture (larger minimum f-number) is "slow" because it delivers less light intensity and requires a slower (longer) shutter speed.

What does the speed of a lens mean?
CoT: The relevant sentence in the passage is: Lens speed refers to the maximum aperture diameter, or minimum f-number, of a photographic lens.
