Explanation:

The most infamous and effective gas of the First World War was mustard gas, a vesicant introduced by the Germans in July 1917 before the Third Battle of Ypres. Known to the British as HS (or Hun Stuff), mustard gas was not intended to be a lethal agent (although it was in high doses), but was designed to harass and incapacitate the enemy and contaminate the battlefield. It fired inside artillery shells, and was heavier than air. It perched on the ground in the form of a liquid similar to sherry, and evaporated slowly without sunlight.

The polluting nature of the mustard gas meant that it was not always adequate to support an attack, since the assault infantry would be exposed to the gas during its advance. When Germany launched Operation Michael on March 21, 1918, they saturated the outgoing Flesquières with mustard gas instead of attacking it directly, believing that the harassing effect of gas coupled with threats to the flanks of the salient, would cause the British position was unsustainable.

The gas was never as successful as it was on April 22, 1915; however, it became a standard weapon that, combined with conventional artillery, was used to support most attacks in the final phases of the war. The Western Front was the main scenario in which the gas was used - the static and confined trenches system was ideal for achieving effective concentration. However, Germany used gas against Russia on the Eastern Front, where the lack of effective countermeasures would result in the death of thousands of Russian soldiers; For its part, the British experimented with gas in Palestine during the Second Battle of Gaza.

answer: a parliamentary system is a system of democratic governance of a state where the executive derives its democratic legitimacy from its ability to command the confidence of the legislature, typically a parliament, and is also held accountable to that parliament. in a parliamentary system, the head of state is usually a person distinct from the head of government. this is in contrast to a presidential system, where the head of state often is also the head of government and, most importantly, the executive does not derive its democratic legitimacy from the legislature.

countries with parliamentary democracies may be constitutional monarchies, where a monarch is the head of state while the head of government is almost always a member of parliament (such as the united kingdom, denmark, sweden, and japan), or parliamentary republics, where a mostly ceremonial president is the head of state while the head of government is regularly from the legislature (such as ireland, germany, india, and italy). in a few parliamentary republics, such as botswana, south africa, and suriname, among some others, the head of government is also head of state, but is elected by and is answerable to parliament. in bicameral parliaments, the head of government is generally, though not always, a member of the lower house.

parliamentarianism is the dominant form of government in europe, with 32 of its 50 sovereign states being parliamentarian. it is also common in the caribbean, being the form of government of 10 of its 13 island states, and in oceania. elsewhere in the world, parliamentary countries are less common, but they are distributed through all continents, most often in former colonies of the british empire that subscribe to a particular brand of parliamentarianism known as the westminster system.

explanation:

an interest group is an organization whose members share common concerns, and try to influence government policies that impact those concerns. elected officials frequently complain about the influence of "special interests" on american politics.
