The problem: Answer a question about this article:
LEDs have been developed by Seoul Semiconductor that can operate on AC power without the need for a DC converter. For each half-cycle, part of the LED emits light and part is dark, and this is reversed during the next half-cycle. The efficacy of this type of HP-LED is typically 40 lm/W. A large number of LED elements in series may be able to operate directly from line voltage. In 2009, Seoul Semiconductor released a high DC voltage LED, named as 'Acrich MJT', capable of being driven from AC power with a simple controlling circuit. The low-power dissipation of these LEDs affords them more flexibility than the original AC LED design.
What is so good about ac powered HP-LEDs?
****
The answer: more flexibility

Question: Read this and answer the question

The Middle Triassic spans from 247 million to 237 million years ago. The Middle Triassic featured the beginnings of the breakup of Pangaea, and the beginning of the Tethys Sea. The ecosystem had recovered from the devastation that was the Great Dying. Phytoplankton, coral, and crustaceans all had recovered, and the reptiles began to get bigger and bigger. New aquatic reptiles evolved such as Ichthyosaurs and Nothosaurs. Meanwhile, on land, Pine forests flourished, bringing along mosquitoes and fruit flies. The first ancient crocodilians evolved, which sparked competition with the large amphibians that had since ruled the freshwater world.

What type of animal began to flourish and become increasingly large?
Answer: reptiles

Problem: There are other annual events, ranging from the Seattle Antiquarian Book Fair & Book Arts Show; an anime convention, Sakura-Con; Penny Arcade Expo, a gaming convention; a two-day, 9,000-rider Seattle to Portland Bicycle Classic, and specialized film festivals, such as the Maelstrom International Fantastic Film Festival, the Seattle Asian American Film Festival (formerly known as the Northwest Asian American Film Festival), Children's Film Festival Seattle, Translation: the Seattle Transgender Film Festival, the Seattle Gay and Lesbian Film Festival, and the Seattle Polish Film Festival.
What anime convention is held in Seattle?
The answer is the following: Sakura-Con

About 40,000,000 tons were produced in 1984[needs update]. It is obtained as the "heavy" (i.e., difficult to distill) fraction. Material with a boiling point greater than around 500 C is considered asphalt. Vacuum distillation separates it from the other components in crude oil (such as naphtha, gasoline and diesel). The resulting material is typically further treated to extract small but valuable amounts of lubricants and to adjust the properties of the material to suit applications. In a de-asphalting unit, the crude asphalt is treated with either propane or butane in a supercritical phase to extract the lighter molecules, which are then separated. Further processing is possible by "blowing" the product: namely reacting it with oxygen. This step makes the product harder and more viscous.
How many tons of bitumen ere produced in 1984?
40,000,000

Here is a question about this article: Unicode can be implemented by different character encodings. The most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same code values in both UTF-8 and ASCII encoding, and up to four bytes for other characters. UCS-2 uses a 16-bit code unit (two 8-bit bytes) for each character but cannot encode every character in the current Unicode standard. UTF-16 extends UCS-2, using one 16-bit unit for the characters that were representable in UCS-2 and two 16-bit units (4 8 bits) to handle each of the additional characters.
What is the answer to this question: What does UTF-8 use in terms of bytes?
****
So...
UTF-8 uses one byte for any ASCII character
