Reading Comprehension

I was going through the OG-12 RC section.
I found that the last 8-10 paragraphs are extremely difficult to me.
Forget about 8-12 minutes, I cann't solve them correctly in 20-30 minutes.
I don't know, what to do for such type of passages.

Just want to know others response for OG-12 last RCs.
Also can somebody tell me that out of 4 passages, how many are simple, difficult or very difficult ?

I felt that length of passage and complexity of arguement is considered as a difficulty measuring tool. Many passages in OG 12th ed are as difficult as the last one. Sometime scientific terms make passage difficult and sometime writing structure.
