Here's how a good student (you) should do it:
1) Read the title. It's about age and how old you feel. What do you know about that?
2) Quickly read the text. Reading the two paragraphs gives us an idea of the topic - the gerontologist thinks we should test for biological age to see when people should retire.
3) Look at question 1. Which option collocates with every? Maybe you think every position and every aspect sound good, but you're not sure which one is right. Just choose one and go to the next question. This is a part of the test where we don't want to spend too much time.
