Here you are being asked to provide a comparison in detail of the causes and any possible effects of how the thing under consideration has developed or happened. Wherever it is possible ,try to give examples, this is especially true if the material offered has examples within it. If the term “critically" is prior to the term analyse. This is telling you that you need to make suggestions as to possibly why or why not something may or may not, in your own opinion, be appropriate considering the issue or event being analysed. Always try to offer support to your findings and/or opinions. For example: Analyse the extent to which foreign aid promotes economic development.

Apply
This as the word suggests is asking you to apply your knowledge of a particular thing, say the monetary or fiscal policy, to a given situation. It is asking you to relate your own specific knowledge of the issue from the syllabus area to the particular situation that has been given to you.

Assess

Compare/Compare and contrast
Asks students to describe two situations and present the similarities and differences between them. A description of the two situations does not on its own meet the requirements of this key term.

Students should weigh the nature of the evidence available and discuss the convincing aspects of an argument as well as its implications and limitations, and the less convincing elements within an argument. For example: Evaluate alternative policies designed to reduce inflation.
Evaluation occurs when a judgment is made. It is the weighing or measuring of factors followed by an attempt to give relative weight to those factors. Questions that begin "evaluate", "assess", "critically assess", "discuss" or "to what extent" require students to show their skills of evaluation in order to reach the highest achievement levels.
There are many ways that students can be encouraged to improve their skills of evaluation.
When factors such as causes, consequences or remedies are asked for, students should attempt to identify the most important ones and then to justify the reason for the choice.
When advantages and disadvantages are asked for, students should attempt to identify the most important advantage (or disadvantage) and then justify the reason for the choice.
When strategies are asked for, students should attempt to assess the short term and long term implications.
When data is offered, students may question its validity, in terms of whether it is appropriate, whether it is reliable, or whether it is still relevant

What

Which
This question is asking you to make a decision from the range of choices, decisions or methods etc. You must offer reasons as to why you chose to support the decision that you did.
