Problem: Light-emitting diode:

High-power LEDs (HP-LEDs) or high-output LEDs (HO-LEDs) can be driven at currents from hundreds of mA to more than an ampere, compared with the tens of mA for other LEDs. Some can emit over a thousand lumens. LED power densities up to 300 W/cm2 have been achieved. Since overheating is destructive, the HP-LEDs must be mounted on a heat sink to allow for heat dissipation. If the heat from a HP-LED is not removed, the device will fail in seconds. One HP-LED can often replace an incandescent bulb in a flashlight, or be set in an array to form a powerful LED lamp.

What can one high-power LED replace?
---
A: incandescent bulb in a flashlight

Problem: Bush's margin of victory in the popular vote was the smallest ever for a reelected incumbent president, but marked the first time since his father's victory 16 years prior that a candidate won a majority of the popular vote. The electoral map closely resembled that of 2000, with only three states changing sides: New Mexico and Iowa voted Republican in 2004 after having voted Democratic in 2000, while New Hampshire voted Democratic in 2004 after previously voting Republican. In the Electoral College, Bush received 286 votes to Kerry's 252.
What was the first state Bush's father campaigned in?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Spielberg then revisited his Close Encounters project and, with financial backing from Columbia Pictures, released Close Encounters: The Special Edition in 1980. For this, Spielberg fixed some of the flaws he thought impeded the original 1977 version of the film and also, at the behest of Columbia, and as a condition of Spielberg revising the film, shot additional footage showing the audience the interior of the mothership seen at the end of the film (a decision Spielberg would later regret as he felt the interior of the mothership should have remained a mystery). Nevertheless, the re-release was a moderate success, while the 2001 DVD release of the film restored the original ending.
What new footage did Columbia require for a Close Encounters revisit?
A: the interior of the mothership

Context and question: By 59 BC an unofficial political alliance known as the First Triumvirate was formed between Gaius Julius Caesar, Marcus Licinius Crassus, and Gnaeus Pompeius Magnus ("Pompey the Great") to share power and influence. In 53 BC, Crassus launched a Roman invasion of the Parthian Empire (modern Iraq and Iran). After initial successes, he marched his army deep into the desert; but here his army was cut off deep in enemy territory, surrounded and slaughtered at the Battle of Carrhae in which Crassus himself perished. The death of Crassus removed some of the balance in the Triumvirate and, consequently, Caesar and Pompey began to move apart. While Caesar was fighting in Gaul, Pompey proceeded with a legislative agenda for Rome that revealed that he was at best ambivalent towards Caesar and perhaps now covertly allied with Caesar's political enemies. In 51 BC, some Roman senators demanded that Caesar not be permitted to stand for consul unless he turned over control of his armies to the state, which would have left Caesar defenceless before his enemies. Caesar chose civil war over laying down his command and facing trial.
Who started the invasion of the Parthian Empire?
Answer: Crassus

Question: In 1998, Democratic voters dominated areas of the state with a high percentage of racial minorities and transplanted white liberals from the northeastern United States, known colloquially as "snowbirds". South Florida and the Miami metropolitan area are dominated by both racial minorities and white liberals. Because of this, the area has consistently voted as one of the most Democratic areas of the state. The Daytona Beach area is similar demographically and the city of Orlando has a large Hispanic population, which has often favored Democrats. Republicans, made up mostly of white conservatives, have dominated throughout much of the rest of Florida, particularly in the more rural and suburban areas. This is characteristic of its voter base throughout the Deep South.
Is there an answer to this question: What party dominates South Florida and Miami

Answer: racial minorities and white liberals. Because of this, the area has consistently voted as one of the most Democratic areas of the state

Question: Microbiological culture is a principal tool used to diagnose infectious disease. In a microbial culture, a growth medium is provided for a specific agent. A sample taken from potentially diseased tissue or fluid is then tested for the presence of an infectious agent able to grow within that medium. Most pathogenic bacteria are easily grown on nutrient agar, a form of solid medium that supplies carbohydrates and proteins necessary for growth of a bacterium, along with copious amounts of water. A single bacterium will grow into a visible mound on the surface of the plate called a colony, which may be separated from other colonies or melded together into a "lawn". The size, color, shape and form of a colony is characteristic of the bacterial species, its specific genetic makeup (its strain), and the environment that supports its growth. Other ingredients are often added to the plate to aid in identification. Plates may contain substances that permit the growth of some bacteria and not others, or that change color in response to certain bacteria and not others. Bacteriological plates such as these are commonly used in the clinical identification of infectious bacterium. Microbial culture may also be used in the identification of viruses: the medium in this case being cells grown in culture that the virus can infect, and then alter or kill. In the case of viral identification, a region of dead cells results from viral growth, and is called a "plaque". Eukaryotic parasites may also be grown in culture as a means of identifying a particular agent.
Is there an answer to this question: What is a planet of dead cells resulting from viral growth called?

Answer:
unanswerable
