Problem: Portugal:

After annexing the County of Portugal into one of the several counties that made up the Kingdom of Asturias, King Alfonso III of Asturias knighted Vimara Peres, in 868 AD, as the First Count of Portus Cale (Portugal). The region became known as Portucale, Portugale, and simultaneously Portugália — the County of Portugal. Later the Kingdom of Asturias was divided into a number of Christian Kingdoms in Northern Spain due to dynastic divisions of inheritance among the kings offspring. With the forced abdication of Alfonso III "the Great" of Asturias by his sons in 910, the Kingdom of Asturias split into three separate kingdoms of León, Galicia and Asturias. The three kingdoms were eventually reunited in 924 (León and Galicia in 914, Asturias later) under the crown of León.

Why was the Kingdom of Asturias divided?

A: dynastic divisions of inheritance among the kings offspring


Problem: Because of their long life, fast switching times, and their ability to be seen in broad daylight due to their high output and focus, LEDs have been used in brake lights for cars' high-mounted brake lights, trucks, and buses, and in turn signals for some time, but many vehicles now use LEDs for their rear light clusters. The use in brakes improves safety, due to a great reduction in the time needed to light fully, or faster rise time, up to 0.5 second faster[citation needed] than an incandescent bulb. This gives drivers behind more time to react. In a dual intensity circuit (rear markers and brakes) if the LEDs are not pulsed at a fast enough frequency, they can create a phantom array, where ghost images of the LED will appear if the eyes quickly scan across the array. White LED headlamps are starting to be used. Using LEDs has styling advantages because LEDs can form much thinner lights than incandescent lamps with parabolic reflectors.
 What color LEDs are now not used more?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Architectural design competitions are used by an organisation that plans to build a new building or refurbish an existing building. They can be used for buildings, engineering work, structures, landscape design projects or public realm artworks. A competition typically asks for architects and/or designers to submit a design proposal in response to a given Brief. The winning design will then be selected by an independent jury panel of design professionals and client representatives. The independence of the jury is vital to the fair conduct of a competition.
What is not provided to guide entrants in an architectural competition?
A: unanswerable


Context and question: Immigration to the United States of Spanish-speaking Cubans began because of Cuba's political instability upon achieving independence. The deposition of Fulgencio Batista's dictatorship and the ascension of Fidel Castro's government in 1959 increased Cuban immigration to the United States, hence there are some one million Cubans in the United States, most settled in southern and central Florida, while other Cubans live in the Northeastern United States; most are fluent in Spanish. In the city of Miami today Spanish is the first language mostly due to Cuban immigration.
Why did Baptista come to United States?
Answer: unanswerable


Question: Alaska is the northernmost and westernmost state in the United States and has the most easterly longitude in the United States because the Aleutian Islands extend into the eastern hemisphere. Alaska is the only non-contiguous U.S. state on continental North America; about 500 miles (800 km) of British Columbia (Canada) separates Alaska from Washington. It is technically part of the continental U.S., but is sometimes not included in colloquial use; Alaska is not part of the contiguous U.S., often called "the Lower 48". The capital city, Juneau, is situated on the mainland of the North American continent but is not connected by road to the rest of the North American highway system.
Is there an answer to this question: How many miles are between Alaska and Washington DC?

Answer: unanswerable


The alcohol in beer comes primarily from the metabolism of sugars that are produced during fermentation. The quantity of fermentable sugars in the wort and the variety of yeast used to ferment the wort are the primary factors that determine the amount of alcohol in the final beer. Additional fermentable sugars are sometimes added to increase alcohol content, and enzymes are often added to the wort for certain styles of beer (primarily "light" beers) to convert more complex carbohydrates (starches) to fermentable sugars. Alcohol is a by-product of yeast metabolism and is toxic to the yeast; typical brewing yeast cannot survive at alcohol concentrations above 12% by volume. Low temperatures and too little fermentation time decreases the effectiveness of yeasts and consequently decreases the alcohol content.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What could decrease alcohol content during the brewing process?
Ah, so..
Low temperatures
