Problem: Please answer a question about the following article about Incandescent light bulb:
To improve the efficiency of the lamp, the filament usually consists of multiple coils of coiled fine wire, also known as a 'coiled coil'. For a 60-watt 120-volt lamp, the uncoiled length of the tungsten filament is usually 22.8 inches (580 mm), and the filament diameter is 0.0018 inches (0.046 mm). The advantage of the coiled coil is that evaporation of the tungsten filament is at the rate of a tungsten cylinder having a diameter equal to that of the coiled coil. The coiled-coil filament evaporates more slowly than a straight filament of the same surface area and light-emitting power. As a result, the filament can then run hotter, which results in a more efficient light source, while reducing the evaporation so that the filament will last longer than a straight filament at the same temperature.
What is the advantage of a coiled-coil filament over a straight filament?
A: The coiled-coil filament evaporates more slowly

Problem: Please answer a question about the following article about Northwestern University:
The Chicago Transit Authority's elevated train running through Evanston is called the Purple Line, taking its name from Northwestern's school color. The Foster and Davis stations are within walking distance of the southern end of the campus, while the Noyes station is close to the northern end of the campus. The Central station is close to Ryan Field, Northwestern's football stadium. The Evanston Davis Street Metra station serves the Northwestern campus in downtown Evanston and the Evanston Central Street Metra station is near Ryan Field. Pace Suburban Bus Service and the CTA have several bus routes that run through or near the Evanston campus.
What was Chicago's Purple Line train route named after?
A:
Northwestern's school color
