in how many days of daily article reading can one become good at comprehension for cat

It depends on how you read the articles. If you read passively then you won't see any improvement. What you have to do is Active Reading- Mentally summarize every paragraph in your mind. Understand the main idea of the passage, the tone of the author, the inferences and everything properly. And read very slowly. Right now Reading speed is not your concern but comprehending the passage is your target. Speed will follow. So read one or two articles and understand it properly instead of rushing and not understanding anything. Get 30-40 mins of continuous reading. You can read Aeon essays because it contains dense topics...keep doing it and you'll see improvement within a month. All the best!

Yes, ut totally depends on how you analyse the RCs one by one. The vocab, the linking between phrases, the connectors, the inferences, everything that authors means has to be consumed by us when we sit to analyse the RC we just solved.
