Should I read the long convoluted experimental passages for bio/biochem too before answering qs?

Usually I'm fine with reading the bio passages and answering them, but when I come across the longer experimental passages I feel like it takes me too much time to read and so I definitely lose some accuracy in later answering the questions. Is it super crucial to read the passage beforehand or would it be a decent idea to head to the questions first which will then give me an idea for where to look. (I just feel like I'm wasting a lot of time looking at/ figuring out the relationships etc.... Should I read the long convoluted experimental passages for bio/biochem too before answering qs?
