Problem: Swaziland:

In 2005, the constitution was put into effect. There is still much debate in the country about the constitutional reforms. From the early seventies, there was active resistance to the royal hegemony. Despite complaints from progressive formations, support for the monarchy and the current political system remains strong among the majority of the population.[citation needed] Submissions were made by citizens around the country to commissions, including the constitutional draft committee, indicating that they would prefer to maintain the current situation.

What do progressive formations support besides the current political system?

Problem: Film speed:

Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor.

Higher sensitivity leads to greater what?

A: unanswerable


Problem: Railway electrification system:

Disadvantages of electric traction include high capital costs that may be uneconomic on lightly trafficked routes; a relative lack of flexibility since electric trains need electrified tracks or onboard supercapacitors and charging infrastructure at stations; and a vulnerability to power interruptions. Different regions may use different supply voltages and frequencies, complicating through service. The limited clearances available under catenaries may preclude efficient double-stack container service. The lethal voltages on contact wires and third rails are a safety hazard to track workers, passengers and trespassers. Overhead wires are safer than third rails, but they are often considered unsightly.

Third rails are considered safer than overhead wires, but are considered what?

A: unanswerable


Problem: Queen Victoria:

Victoria was physically unprepossessing—she was stout, dowdy and no more than five feet tall—but she succeeded in projecting a grand image. She experienced unpopularity during the first years of her widowhood, but was well liked during the 1880s and 1890s, when she embodied the empire as a benevolent matriarchal figure. Only after the release of her diary and letters did the extent of her political influence become known to the wider public. Biographies of Victoria written before much of the primary material became available, such as Lytton Strachey's Queen Victoria of 1921, are now considered out of date. The biographies written by Elizabeth Longford and Cecil Woodham-Smith, in 1964 and 1972 respectively, are still widely admired. They, and others, conclude that as a person Victoria was emotional, obstinate, honest, and straight-talking.

What kind of person was Victoria?
---
A:
emotional, obstinate, honest, and straight-talking
