Problem: Phonology:

In 1976 John Goldsmith introduced autosegmental phonology. Phonological phenomena are no longer seen as operating on one linear sequence of segments, called phonemes or feature combinations, but rather as involving some parallel sequences of features which reside on multiple tiers. Autosegmental phonology later evolved into feature geometry, which became the standard theory of representation for theories of the organization of phonology as different as lexical phonology and optimality theory.

What did operating tiers morph into?

A: unanswerable

Problem: Crucifixion of Jesus:

John Calvin supported the "agent of God" Christology and argued that in his trial in Pilate's Court Jesus could have successfully argued for his innocence, but instead submitted to crucifixion in obedience to the Father. This Christological theme continued into the 20th century, both in the Eastern and Western Churches. In the Eastern Church Sergei Bulgakov argued that the crucifixion of Jesus was "pre-eternally" determined by the Father before the creation of the world, to redeem humanity from the disgrace caused by the fall of Adam. In the Western Church, Karl Rahner elaborated on the analogy that the blood of the Lamb of God (and the water from the side of Jesus) shed at the crucifixion had a cleansing nature, similar to baptismal water.

Why did Jesus submit to crucifixion?
---
A: obedience to the Father

Problem: Bacteria:

Most bacterial species are either spherical, called cocci (sing. coccus, from Greek kokkos, grain, seed), or rod-shaped, called bacilli (sing. bacillus, from Latin baculus, stick). Elongation is associated with swimming. Some bacteria, called vibrio, are shaped like slightly curved rods or comma-shaped; others can be spiral-shaped, called spirilla, or tightly coiled, called spirochaetes. A small number of species even have tetrahedral or cuboidal shapes. More recently, some bacteria were discovered deep under Earth's crust that grow as branching filamentous types with a star-shaped cross-section. The large surface area to volume ratio of this morphology may give these bacteria an advantage in nutrient-poor environments. This wide variety of shapes is determined by the bacterial cell wall and cytoskeleton, and is important because it can influence the ability of bacteria to acquire nutrients, attach to surfaces, swim through liquids and escape predators.

Can shape of bacteria be beneficial to their survival?
---
A: can influence the ability of bacteria to acquire nutrients

Problem: Elizabeth II:

According to Paul Martin, Sr., by the end of the 1970s the Queen was worried that the Crown "had little meaning for" Pierre Trudeau, the Canadian Prime Minister. Tony Benn said that the Queen found Trudeau "rather disappointing". Trudeau's supposed republicanism seemed to be confirmed by his antics, such as sliding down banisters at Buckingham Palace and pirouetting behind the Queen's back in 1977, and the removal of various Canadian royal symbols during his term of office. In 1980, Canadian politicians sent to London to discuss the patriation of the Canadian constitution found the Queen "better informed ... than any of the British politicians or bureaucrats". She was particularly interested after the failure of Bill C-60, which would have affected her role as head of state. Patriation removed the role of the British parliament from the Canadian constitution, but the monarchy was retained. Trudeau said in his memoirs that the Queen favoured his attempt to reform the constitution and that he was impressed by "the grace she displayed in public" and "the wisdom she showed in private".

In what year did Pierre Trudeau become the Canadian prime minister?

A:
