Wow - this is complicated! This paragraph is a major confusion of tenses. Let's try to simplify it. I'm sure that will make it much easier.
First, sit back and think about where we are in time. It seems the research has taken place, and this is your report. Now locate all the working verbs in the four sentences. Where are they? Highlight them. This should help you to link the tenses in a way that makes sense. Your verbs need to 'agree' with each other, which means that the tenses you choose should keep the text moving smoothly, rather than jumping from one time to another!
Now let's separate the four sentences and look at what they do. The first sets out the objective of the research, the second tells us what you did, the third what you found and the last is a conclusion.
So: now we know where we are and what we have to do. Start at the beginning with the very first verb and work through it one sentence at a time. Give it a try and post it up again so I can see how you get on.
Also I would suggest some other changes:
'How they pertain to the text' not 'pertaining to', because this is not a continuing action with a start and finish but something that happens all the time;
'clarify its meaning' not 'understand its meaning', because a figure of speech cannot understand anything;
'gave it visualization' not 'gave for the text visualization', because you've already just used 'the text' so you can use a pronoun here. 'for' is unnecessary;
'stimulate imagination' would be better than 'bring about', because imagination is not something that can be brought about - it's always there, but can be stimulated, or encouraged.
No need to be embarrassed about admitting defeat with this - it's not at all easy. I think you're doing very well indeed to be working at this level.
