Problem: Wood:

If a heavy piece of pine is compared with a lightweight piece it will be seen at once that the heavier one contains a larger proportion of latewood than the other, and is therefore showing more clearly demarcated growth rings. In white pines there is not much contrast between the different parts of the ring, and as a result the wood is very uniform in texture and is easy to work. In hard pines, on the other hand, the latewood is very dense and is deep-colored, presenting a very decided contrast to the soft, straw-colored earlywood.

What type of tree has very little contrast between parts of its growth rings?
---
A: white pines


Problem: Several species of pines characteristic of the Appalachians are eastern white pine (Pinus strobus ), Virginia pine (Pinus virginiana), pitch pine (Pinus rigida ), Table Mountain pine (Pinus pungens) and shortleaf pine (Pinus echinata). Red pine (Pinus resinosa) is a boreal species that forms a few high elevation outliers as far south as West Virginia. All of these species except white pine tend to occupy sandy, rocky, poor soil sites, which are mostly acidic in character. White pine, a large species valued for its timber, tends to do best in rich, moist soil, either acidic or alkaline in character. Pitch pine is also at home in acidic, boggy soil, and Table Mountain pine may occasionally be found in this habitat as well. Shortleaf pine is generally found in warmer habitats and at lower elevations than the other species. All the species listed do best in open or lightly shaded habitats, although white pine also thrives in shady coves, valleys, and on floodplains.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
It is fairly clear that predators tend to lower the survival and fecundity of their prey, but on a higher level of organization, populations of predator and prey species also interact. It is obvious that predators depend on prey for survival, and this is reflected in predator populations being affected by changes in prey populations. It is not so obvious, however, that predators affect prey populations. Eating a prey organism may simply make room for another if the prey population is approaching its carrying capacity.
Predators lower what aspects of their prey?
A: survival and fecundity


Context and question: Anglicanism comprises the Church of England and churches which are historically tied to it or hold similar beliefs, worship practices and church structures. The word Anglican originates in ecclesia anglicana, a medieval Latin phrase dating to at least 1246 that means the English Church. There is no single "Anglican Church" with universal juridical authority, since each national or regional church has full autonomy. As the name suggests, the communion is an association of churches in full communion with the Archbishop of Canterbury. The great majority of Anglicans are members of churches which are part of the international Anglican Communion, which has 80 million adherents.
How many Anglican Communion members are there in the world?
Answer: 80 million


Question: Cockfighting is said to be the world's oldest spectator sport and may have originated in Persia 6,000 years ago. Two mature males (cocks or roosters) are set to fight each other, and will do so with great vigour until one is critically injured or killed. Breeds such as the Aseel were developed in the Indian subcontinent for their aggressive behaviour. The sport formed part of the culture of the ancient Indians, Chinese, Greeks, and Romans, and large sums were won or lost depending on the outcome of an encounter. Cockfighting has been banned in many countries during the last century on the grounds of cruelty to animals.
Is there an answer to this question: Why is cockfighting no longer something people want to be involved with?

Answer: unanswerable


QUES: In 1985, the combination of the Mac, Apple's LaserWriter printer, and Mac-specific software like Boston Software's MacPublisher and Aldus PageMaker enabled users to design, preview, and print page layouts complete with text and graphics—an activity to become known as desktop publishing. Initially, desktop publishing was unique to the Macintosh, but eventually became available for other platforms. Later, applications such as Macromedia FreeHand, QuarkXPress, and Adobe's Photoshop and Illustrator strengthened the Mac's position as a graphics computer and helped to expand the emerging desktop publishing market.

What applications strengthened Mac's position as a graphics computer?
What is the answer?
ANS:
Macromedia FreeHand, QuarkXPress, and Adobe's Photoshop and Illustrator
