Problem: Indigenous peoples of the Americas:

Most Venezuelans have some indigenous heritage, but the indigenous population make up only around 2% of the total population. They speak around 29 different languages and many more dialects, but some of the ethnic groups are very small and their languages are in danger of becoming extinct in the next decades. The most important indigenous groups are the Ye'kuana, the Wayuu, the Pemon and the Warao. The most advanced native people to have lived in present-day Venezuela is thought to have been the Timoto-cuicas, who mainly lived in the Venezuelan Andes. In total it is estimated that there were between 350 thousand and 500 thousand inhabitants, the most densely populated area being the Andean region (Timoto-cuicas), thanks to the advanced agricultural techniques used.

What do most Venezuelans have?

A: some indigenous heritage

Problem: The word "public" implies the highest level of inclusivity the public sphere by definition should be open to all. However, this sphere was only public to relative degrees. Enlightenment thinkers frequently contrasted their conception of the "public" with that of the people: Condorcet contrasted "opinion" with populace, Marmontel "the opinion of men of letters" with "the opinion of the multitude," and d'Alembert the "truly enlightened public" with "the blind and noisy multitude". Additionally, most institutions of the public sphere excluded both women and the lower classes. Cross-class influences occurred through noble and lower class participation in areas such as the coffeehouses and the Masonic lodges.
Whixh population groups were excluded from most institutions of the public sphere?

Answer: women and the lower classes

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Wildfires plague the forested areas of Guam every dry season despite the island's humid climate. Most fires are man-caused with 80% resulting from arson. Poachers often start fires to attract deer to the new growth. Invasive grass species that rely on fire as part of their natural life cycle grow in many regularly burned areas. Grasslands and "barrens" have replaced previously forested areas leading to greater soil erosion. During the rainy season sediment is carried by the heavy rains into the Fena Lake Reservoir and Ugum River, leading to water quality problems for southern Guam. Eroded silt also destroys the marine life in reefs around the island. Soil stabilization efforts by volunteers and forestry workers (planting trees) have had little success in preserving natural habitats.
What causes water quality problems in Guam?
A: sediment is carried by the heavy rains into the Fena Lake Reservoir and Ugum River

Context and question: Furthermore, Apple had created too many similar models that confused potential buyers. At one point, its product lineup was subdivided into Classic, LC, II, Quadra, Performa, and Centris models, with essentially the same computer being sold under a number of different names. These models competed against Macintosh clones, hardware manufactured by third parties that ran Apple's System 7. This succeeded in increasing the Macintosh's market share somewhat, and provided cheaper hardware for consumers, but hurt Apple financially as existing Apple customers began to buy cheaper clones which cannibalized the sales of Apple's higher-margin Macintosh systems, yet Apple still shouldered the burden of developing the Mac OS platform.
What did Apple's creation of too many similar models do to potential buyers?
Answer: confused potential buyers

Question: Archival descriptions of the permanent holdings of the federal government in the custody of NARA are stored in Archival Research Catalog (ARC). The archival descriptions include information on traditional paper holdings, electronic records, and artifacts. As of December 2012, the catalog consisted of about 10 billion logical data records describing 527,000 artifacts and encompassing 81% of NARA's records. There are also 922,000 digital copies of already digitized materials.
Is there an answer to this question: As of the end mid December of 2012, how many logical data records are stored at NARA?

Answer: 10 billion

In additive color devices such as computer displays and televisions, one of the primary light sources is typically a narrow-spectrum yellowish-green of dominant wavelength ~550 nm; this "green" primary is combined with an orangish-red "red" primary and a purplish-blue "blue" primary to produce any color in between the RGB color model. A unique green (green appearing neither yellowish nor bluish) is produced on such a device by mixing light from the green primary with some light from the blue primary.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What are examples of devices that do not use additive systems?
Ah, so..
unanswerable
