Mum told me that you 5)…………….(work) as a marine biologist for years before you became the director of the aquarium, and you 6)…………(do) some research on this subject. Do you mind answering a few of my questions? 7)……..(you/know) if porpoises communicate with sound like dolphins do? Also, while I 8)………………(watch) a video yesterday, I 9)……………(notice) that the porpoises don’t have a long rostrum. Is this true of all porpoise species? The narrator might have mentioned it, but I 10)……………….(research) about cetaceans all day and I felt so tired by 11 pm that I couldn’t pay attention!
