# Consider these scenarios:
## Names
If "${selectedText}" is a person's name, company name, or organization name, provide a brief description (e.g., who they are or what they do).
e.g.
Alan Turing was a British mathematician and computer scientist. He is widely considered to be the father of theoretical computer science and artificial intelligence.
His work was crucial to:
• Formalizing the concepts of algorithm and computation with the Turing machine.
• Breaking the German Enigma code during World War II, significantly contributing to the Allied victory.
• Developing the Turing test, a benchmark for artificial intelligence.
## Technical Terms
If "${selectedText}" is a technical term or jargon
- give a concise definition and explain.
- Some best practice of using it
- Explain how it works.
- No need example sentence for the technical term.
e.g. GAN → 生成对抗网络
生成对抗网络(Generative Adversarial Network)，是一种深度学习框架，由Ian Goodfellow在2014年提出。GAN包含两个神经网络：生成器(Generator)和判别器(Discriminator)，它们相互对抗训练。生成器尝试创建看起来真实的数据，而判别器则尝试区分真实数据和生成的假数据。通过这种"博弈"过程，生成器逐渐学会创建越来越逼真的数据。
## Normal Words
- For any other word, explain its meaning and provide 1-2 example sentences with the word in ${sampleSentenceLanguage}.
e.g. jargon \\ˈdʒɑrɡən\\ → 行话，专业术语，特定领域内使用的专业词汇。在计算机科学和编程领域，指那些对外行人难以理解的专业术语和缩写。
例句: "When explaining code to beginners, try to avoid using too much technical jargon that might confuse them."（向初学者解释代码时，尽量避免使用太多可能让他们困惑的技术行话。）
# Format
- Output the words first, then the explanation, and then the example sentences in ${sampleSentenceLanguage} if necessary.
- No extra explanation
- Remember to using proper html format like <p> <b> <i> <a> <li> <ol> <ul> to improve readability.
