Problem: Glacier:

Glaciers form where the accumulation of snow and ice exceeds ablation. The area in which a glacier forms is called a cirque (corrie or cwm) - a typically armchair-shaped geological feature (such as a depression between mountains enclosed by aretes) - which collects and compresses through gravity the snow which falls into it. This snow collects and is compacted by the weight of the snow falling above it forming neve. Further crushing of the individual snowflakes and squeezing the air from the snow turns it into 'glacial ice'. This glacial ice will fill the cirque until it 'overflows' through a geological weakness or vacancy, such as the gap between two mountains. When the mass of snow and ice is sufficiently thick, it begins to move due to a combination of surface slope, gravity and pressure. On steeper slopes, this can occur with as little as 15 m (50 ft) of snow-ice.

What happens in a minimum of 15 feet of snow?
---
A: unanswerable

Problem: Tuberculosis:

In Europe, rates of tuberculosis began to rise in the early 1600s to a peak level in the 1800s, when it caused nearly 25% of all deaths. By the 1950s, mortality had decreased nearly 90%. Improvements in public health began significantly reducing rates of tuberculosis even before the arrival of streptomycin and other antibiotics, although the disease remained a significant threat to public health such that when the Medical Research Council was formed in Britain in 1913, its initial focus was tuberculosis research.

What British health organization made tuberculosis its top priority at its start?
---
A: Medical Research Council

Problem: Tuberculosis:

One way to decrease stigma may be through the promotion of "TB clubs", where those infected may share experiences and offer support, or through counseling. Some studies have shown TB education programs to be effective in decreasing stigma, and may thus be effective in increasing treatment adherence. Despite this, studies on relationship between reduced stigma and mortality are lacking as of 2010, and similar efforts to decrease stigma surrounding AIDS have been minimally effective. Some have claimed the stigma to be worse than the disease, and healthcare providers may unintentionally reinforce stigma, as those with TB are often perceived as difficult or otherwise undesirable. A greater understanding of the social and cultural dimensions of tuberculosis may also help with stigma reduction.

What do some people say is even worse than the effects of tuberculosis itself?
---
A: the stigma

Problem: Literature:

Hogan also explains that the temporal and emotional amount which a person devotes to understanding a character's situation in literature allows literature to be considered "ecological[ly] valid in the study of emotion". This can be understood in the sense that literature unites a large community by provoking universal emotions. It also allows readers to access cultural aspects that they are not exposed to thus provoking new emotional experiences. Authors choose literary device according to what psychological emotion he or she is attempting to describe, thus certain literary devices are more emotionally effective than others.

What determines what literary structure a literary author uses for expression of ideas?
---
A:
what psychological emotion he or she is attempting to describe
