Problem: Symbiosis:

Synnecrosis is a rare type of symbiosis in which the interaction between species is detrimental to both organisms involved. It is a short-lived condition, as the interaction eventually causes death. Because of this, evolution selects against synnecrosis and it is uncommon in nature. An example of this is the relationship between some species of bees and victims of the bee sting. Species of bees who die after stinging their prey inflict pain on themselves (albeit to protect the hive) as well as on the victim. This term is rarely used.

Why do bees sting even though it will kill them?
---
A: to protect the hive


Problem: Clothing:

Clothing can and has in history been made from a very wide variety of materials. Materials have ranged from leather and furs, to woven materials, to elaborate and exotic natural and synthetic fabrics. Not all body coverings are regarded as clothing. Articles carried rather than worn (such as purses), worn on a single part of the body and easily removed (scarves), worn purely for adornment (jewelry), or those that serve a function other than protection (eyeglasses), are normally considered accessories rather than clothing, as are footwear and hats.

Footwear and hats are consider clothing rather than what?
---
A: unanswerable


Problem: A cappella:

In the Byzantine Rite of the Eastern Orthodox Church and the Eastern Catholic Churches, the music performed in the liturgies is exclusively sung without instrumental accompaniment. Bishop Kallistos Ware says, "The service is sung, even though there may be no choir... In the Orthodox Church today, as in the early Church, singing is unaccompanied and instrumental music is not found." This a cappella behavior arises from strict interpretation of Psalms 150, which states, Let every thing that hath breath praise the Lord. Praise ye the Lord. In keeping with this philosophy, early Russian musika which started appearing in the late 17th century, in what was known as khorovïye kontsertï (choral concertos) made a cappella adaptations of Venetian-styled pieces, such as the treatise, Grammatika musikiyskaya (1675), by Nikolai Diletsky. Divine Liturgies and Western Rite masses composed by famous composers such as Peter Tchaikovsky, Sergei Rachmaninoff, Alexander Arkhangelsky, and Mykola Leontovych are fine examples of this.

What type of music made a cappella versions of instrumental accompaniment?
---
A: unanswerable


Problem: Dwight D. Eisenhower:

That evening, Eisenhower's body was placed onto a train en route to Abilene, Kansas, the last time a funeral train has been used as part of funeral proceedings of an American president. His body arrived on April 2, and was interred later that day in a small chapel on the grounds of the Eisenhower Presidential Library. The president's body was buried as a General of the Army. The family used an $80 standard soldier's casket, and dressed Eisenhower's body in his famous short green jacket. His only medals worn were: the Army Distinguished Service Medal with three oak leaf clusters, the Navy Distinguished Service Medal, and the Legion of Merit. Eisenhower is buried alongside his son Doud, who died at age 3 in 1921. His wife Mamie was buried next to him after her death in 1979.

When did Mamie Eisenhower die?
