TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: What is Rayleigh scattering?, Context: In nature, the red color of blood comes from hemoglobin, the iron-containing protein found in the red blood cells of all vertebrates. The red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars. The red sky at sunset and sunrise is caused by an optical effect known as Rayleigh scattering, which, when the sun is low or below the horizon, increases the red-wavelength light that reaches the eye. The color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the human population has red hair; the color is produced by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin.

SOLUTION: optical effect

PROBLEM: What might be pleasing to look at?, Context: Lighting fixtures come in a wide variety of styles for various functions. The most important functions are as a holder for the light source, to provide directed light and to avoid visual glare. Some are very plain and functional, while some are pieces of art in themselves. Nearly any material can be used, so long as it can tolerate the excess heat and is in keeping with safety codes.

SOLUTION: Lighting fixtures

PROBLEM: How is the front of the station designed?, Context: In 2014, work was completed on the stations historic entrance. Glazing was placed over the historic arches and the Victorian architecture was enhanced; transforming the 19th century public portico. The station is one of only six Grade One listed railway stations in the UK. Opened in 1850 by Queen Victoria, it was the first covered railway station in the world and was much copied across the UK. It has a neoclassical façade, originally designed by the architect John Dobson, and was constructed in collaboration with Robert Stephenson. The station sightlines towards the Castle Keep, whilst showcasing the curvature of the station’s arched roof. The first services were operated by the North Eastern Railway company. The city's other mainline station, Manors, is to the east of the city centre.

SOLUTION:
neoclassical
