What does 2-3 pages mean? Different website? or same website but different post/page?

I can’t understand any of these tasks.

Already did multiple jobs. I clicked on the highlighted link then waited for the countdown to end but it stuck at 1 sec. Then the job just disappeared telling me I failed.

I don’t understand what it means to visit the link then click 2-3 similar pages. Example if I visit a blog and the timer ends (or stuck at 1) what do I do next? Click on other blog post or go back in the search engine and find another 2-3 websites?
