Problem: Charleston, South Carolina:

On June 28, 1776, General Sir Henry Clinton along with 2,000 men and a naval squadron tried to seize Charles Towne, hoping for a simultaneous Loyalist uprising in South Carolina. When the fleet fired cannonballs, they failed to penetrate Fort Sullivan's unfinished, yet thick, palmetto-log walls. No local Loyalists attacked the town from the mainland side, as the British had hoped they would do. Col. Moultrie's men returned fire and inflicted heavy damage on several of the British ships. The British were forced to withdraw their forces, and the Americans renamed the defensive installation as Fort Moultrie in honor of its commander.

Who was the commander of the American forces defending South Carolina?
---
A: Col. Moultrie

Problem: High-definition television:

Colour broadcasts started at similarly higher resolutions, first with the US NTSC color system in 1953, which was compatible with the earlier monochrome systems and therefore had the same 525 lines of resolution. European standards did not follow until the 1960s, when the PAL and SECAM color systems were added to the monochrome 625 line broadcasts.

How many lines of resolution did the US NTSC color system have in 1953?

A: 525

Problem: Incandescent light bulb:

Incandescent bulbs are much less efficient than most other types of electric lighting; incandescent bulbs convert less than 5% of the energy they use into visible light, with standard light bulbs averaging about 2.2%. The remaining energy is converted into heat. The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared with 60 lm/W for a compact fluorescent bulb or 150 lm/W for some white LED lamps. Some applications of the incandescent bulb deliberately use the heat generated by the filament. Such applications include incubators, brooding boxes for poultry, heat lights for reptile tanks, infrared heating for industrial heating and drying processes, lava lamps, and the Easy-Bake Oven toy. Incandescent bulbs typically have short lifetimes compared with other types of lighting; around 1,000 hours for home light bulbs versus typically 10,000 hours for compact fluorescents and 30,000 hours for lighting LEDs.

Which is more efficient: compact fluorescent or LED lights?
---
A: LED
