Okay, I need to write an original article about "What Animals Are Smart" using the provided context. Let me start by understanding the requirements. The user wants the article between 600-900 words, with natural headings and avoidance of unsupported claims. Also, no mention that it's AI-generated. First, I'll look at the context given. The context mentions various animals like African Gray Parrots, dolphins, octopuses, elephants, and crows. There's also a mention of measuring intellect and some experiments. I need to structure the article around these animals, making sure each has factual, supported information. The introduction should set the stage about animal intelligence being a complex topic. Maybe start with a hook about how humans often think they're the smartest, but there are many intelligent animals. Then mention that measuring intellect is tricky, which ties into the context about scientists making it testable. For each animal section, I need to include specific examples and credible facts. The African Gray Parrot outperforming kids in cognitive tasks is a good point. Dolphins have complex communication and social structures. Octopuses can solve puzzles and escape enclosures. Elephants show empathy and long-term memory. Crows use tools and recognize human faces. Maybe mention a sixth animal if needed, like chimps or another bird. I should avoid unsupported claims, so each fact should be backed by known research. For example, the parrot experiment is referenced in the context, so that's solid. Dolphins' use of sponges as tools is a real study. Octopuses escaping enclosures is documented. Elephants mourning dead is a known behavior. Crows making tools is factual. Headings need to be natural. Maybe start with an introduction, then each animal as a subheading. Then a conclusion about why studying animal intelligence matters. I need to make sure the article flows well, connecting each animal's intelligence to the broader topic. Also, include the call to action for creating an account as per the context, but the URL might be a placeholder. The user provided "https://my.happylearning.tv/" for that. Check the word count. Let me outline each section: - Intro: 100 words - African Gray Parrot: 100 - Dolphins: 100 - Octopuses: 100 - Elephants: 100 - Crows: 100 - Conclusion: 100 That should be about 700 words. Let me start drafting each section with proper headings and supported facts. Wait, the user mentioned not to use markdown, but in the response, they want HTML tags. So I need to structure the article using

    1. , , . Let me make sure to format accordingly. Also, the user wants natural headings. Maybe use h2 for main sections and h3 if needed, but probably just h2 for each animal. Let me check the example response to see how they structured it. Looking at the example response, they used h2 for the intro, then h2 for each animal section. The conclusion was another h2. That's a good model. Let me follow that structure. Now, start writing each section. For the introduction, perhaps a hook about humans not being the only smart beings. Then mention the difficulty in measuring intellect, referencing the context's point about scientists making it testable. Each animal section should have an h2 header, then paragraphs explaining their intelligence. Use specific examples from the context and other known facts. Avoid fluff, stay concise. For the African Gray Parrot, mention the experiment with five-year-olds. Dolphins with their communication and tool use. Octopuses escaping and solving puzzles. Elephants with memory and empathy. Crows using tools and face recognition. In the conclusion, tie it all together, emphasizing that intelligence varies and studying these animals helps us understand cognition better. End with the call to action for the website. Check for any unsupported claims. For example, "octopuses can solve puzzles" is supported by studies. "Crows recognize human faces" is a known fact. All the claims are credible. Make sure the article is engaging and SEO-friendly. Use the keyword "What Animals Are Smart" in the title and naturally within
