Problem: The capital village of each district administers and coordinates the affairs of the district and confers each district's paramount title, amongst other responsibilities. For example, the District of A'ana has its capital at Leulumoega. The paramount title of A'ana is the TuiA'ana. The orator group which confers this title the Faleiva (House of Nine) is based at Leulumoega. This is also the same for the other districts. In the district of Tuamasaga, the paramount title of the district the Malietoa title is conferred by the FaleTuamasaga based in Afega.
What district is Leulumoega the capital of?
The answer is the following: A'ana

Problem: The most common symptom of LED (and diode laser) failure is the gradual lowering of light output and loss of efficiency. Sudden failures, although rare, can also occur. Early red LEDs were notable for their short service life. With the development of high-power LEDs the devices are subjected to higher junction temperatures and higher current densities than traditional devices. This causes stress on the material and may cause early light-output degradation. To quantitatively classify useful lifetime in a standardized manner it has been suggested to use L70 or L50, which are the runtimes (typically given in thousands of hours) at which a given LED reaches 70% and 50% of initial light output, respectively.
What could cause early light-output degradation in LEDs?
The answer is the following: higher junction temperatures

Problem: It is remarkable that the inner heartwood of old trees remains as sound as it usually does, since in many cases it is hundreds, and in a few instances thousands, of years old. Every broken limb or root, or deep wound from fire, insects, or falling timber, may afford an entrance for decay, which, once started, may penetrate to all parts of the trunk. The larvae of many insects bore into the trees and their tunnels remain indefinitely as sources of weakness. Whatever advantages, however, that sapwood may have in this connection are due solely to its relative age and position.
Decay can spread to all of what part of a tree?
The answer is the following: the trunk

Problem: J'ouvert, or "Dirty Mas", takes place before dawn on the Monday (known as Carnival Monday) before Ash Wednesday. It means ""opening of the day". Revelers dress in costumes embodying puns on current affairs, especially political and social events. "Clean Mud" (clay mud), oil paint and body paint are familiar during J'ouvert. A common character is "Jab-jabs" (devils, blue, black or red) complete with pitchfork, pointed horns and tails. A King and Queen of J'ouvert are chosen, based on their witty political/social messages.
What is "Clean Mud"?
The answer is the following:
clay
