Before you attempt to answer an assignment question, you need to make sure you understand what it is asking.
This includes the subject matter, but also the way in which you are required to write.
Different questions may ask you to discuss, outline, evaluate...and many more. The task words are a key part of the question.
Once you have broken down and understood your assignment question, you can start to jot down your ideas, organise your research, and figure out exactly what point you want to argue in your essay.
Here is something to try if you are struggling to get going with responding to the assignment question:
Directive or task words: Tell you exactly what to do e.g., discuss, argue etc.
Subject matter: Specifically what you should be writing about.
Limiting words: Parts of the question that may narrow or alter the focus of your answer.
Example: To what extent can the novel White Teeth by Zadie Smith be read differently in the light of the 9/11 Terrorist Attack?
Some essay questions may have a narrow focus e.g., 'To what extent can it be argued that Byron and Keats are second generation Romantic poets?'.
While other may be quite broad e.g., ' Evaluate the effect of landscape on the expansion of the town'.
The first example indicates exactly which poets to focus on, and which aspect of their work to explore. The second example is much broader: it doesn't specify which features of landscape, or which towns should be analysed.
Even if the essay question is broad, your answer should have a clear and specific focus. Therefore, you need to choose an area of the topic to concentrate on. If answering the second of the two questions above, you would not need to write about the impact if every type of landscape on every town in the world. It is normally better to write a lot about a little, rather than a little about a lot.
It is also important to note that, although the specific essay question tells you which poets to focus on and which aspect of their work to discuss, it does not dictate which way you have to argue. You are still free to choose your own standpoint (based on evidence) as to whether or not Byron and Keats can be seen as second generation Romantic poets.
