Question

I haven't read this newspaper yet . I only looked ... it Upafteroutinthrough

Answer 1

through, только просмотрел ее

Answer 2

It seems like you're describing a way of skimming through the newspaper without reading it thoroughly. The phrase "looked it up after out in through" doesn't seem to form a coherent sentence, so I'll assume you meant to say:

"I haven't read this newspaper yet. I only looked it up after flipping through it."

This means you haven't read the entire newspaper, but instead, you skimmed or flipped through its pages quickly. Then, you later searched for specific information by looking it up elsewhere (possibly online) to get more detailed or specific information about certain topics or articles that caught your attention during your initial browsing.
