The words
Scientists say they have had a "conversation" [with / wither] a whale. They also say the chat could help them to [one / once] day talk to aliens. The scientists [are / be] from the University of California, the Alaska Whale Foundation, and SETI (Search for Extra-terrestrial Intelligence). The three organizations teamed [down / up] and spoke to a humpback whale [name / named] Twain. They spoke to her [at / in] "humpback language" for 20 minutes. Their conversation [took / gave] place after the scientists sent a "contact call" into the ocean off the [coast / cost] of Alaska. Twain heard the call and responded. She swam [at / to] the research boat and chatted. SETI said it was the first [ever / every] communication between humans and humpback whales.

The scientists say their conversation with Twain was not a [depth / deep] one. Professor Brenda McCowan said it was more like a [services / series] of greetings. Whales use contact calls to [bet / let] other whales know where they are. The scientists made the same call 36 times [over / under] a 20-minute period. Each time, Twain responded by calling back. She even matched the intervals [among / between] each call the researchers made. Professor McCowan [told / said] the Business Insider website that her research could make [it / them] easier to talk to aliens. She said: "There are [diverse / drivers] intelligences on this planet. By studying them, we can better [understand / understanding] what an alien intelligence might be like because they are not going to be [exact / exactly] like ours."
