Answer:Purposive sampling
Explanation:
A purposive sampling :
A selection of the participants is done by looking at their characteristics as the overall group or population and dependent on the purpose of the study.
When one needs to tackle a target question fast without the worrying factor of proportinality this is a good sampling method to be chosen.
It can be divided into heterogeneous purposive sample and homogeneous sample .
Heterogeneous tackles various issues which relate to a particular phenomenon. Many number of participants are questioned in order to receive a broader view of the issue in question.
Homogeneous
A homogeneous purposive sample deals with participants that have similar characteristics. The above purposive sample can be said to be a homogeneous one because the professor has an interest on the students who are all high achievers and that is their similar characteristic.
Trench warfare is a type of land warfare using occupied fighting lines consisting largely of trenches, in which troops are significantly protected from the enemy's small arms fire and are substantially sheltered from artillery. The most famous use of trench warfare is the Western Front in World War I. It has become a byword for stalemate, attrition, sieges and futility in conflict.
Trench warfare occurred when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage.[2] On the Western Front in 1914–18, both sides constructed elaborate trench and dugout systems opposing each other along a front, protected from assault by barbed wire, mines, and other obstacles. The area between opposing trench lines (known as "no man's land") was fully exposed to artillery fire from both sides. Attacks, even if successful, often sustained severe casualties
