cuál sería el presente perfecto hay q subrayar

I have been to some interesting museums in my city. I've visited the Museum of Technology, the Art Museum, and the Natural History Museum. Of the three museums, I've gone to the Museum of Technology the most. It is definitely my favorite. In fact, I went there last month. They had an exhibit on communications technology through the years. The exhibit was really popular, and they have extended it for another month. The Art Museum is also excellent. I've gone there only once, but I really enjoyed it. The Natural History Museum is famous for its dinosaurs. I went there a couple years ago on a school trip, but I haven't been there since. My cousins tell me that the museum has gotten a lot better recently. They visited two months ago, and they told me the exhibits were great. Maybe I'll go next weekend!​
