Large language models (LLMs) are highly capable in various question-answering tasks, leveraging their extensive training on diverse datasets to provide accurate and contextually relevant answers. Here are some examples of the types of question-answering tasks that LLMs can perform:

**1. Fact-Based Question Answering

LLMs can answer factual questions based on a wide range of general knowledge acquired during training.

Example:

  • Question: "What is the capital of France?"
  • Answer: "Paris."

**2. Open-Domain Question Answering

In open-domain question answering, LLMs provide answers to questions that are not restricted to any specific domain. They use general knowledge to respond to diverse queries.

Example:

  • Question: "Who wrote the novel '1984'?"
  • Answer: "George Orwell."

**3. Contextual Question Answering

LLMs can provide answers based on specific contexts or passages of text provided by the user. This is often used in tasks like reading comprehension.

Example:

  • Context: "The quick brown fox jumps over the lazy dog. This phrase is often used as a pangram in the English language."
  • Question: "What is a pangram?"
  • Answer: "A pangram is a sentence that contains every letter of the alphabet at least once."

**4. Conversational Question Answering

LLMs can engage in multi-turn dialogues, answering questions based on the context of an ongoing conversation.

Example:

  • Conversation:
    • User: "Can you recommend a good mystery novel?"
    • LLM: "Have you read 'The Girl with the Dragon Tattoo' by Stieg Larsson?"
    • User: "No, I haven't. What's it about?"
    • LLM: "It's about a journalist and a hacker who investigate a wealthy family's dark secrets."

**5. Multiple Choice Question Answering

LLMs can answer questions where the user provides several options to choose from. This is commonly used in educational settings and standardized testing.

Example:

  • Question: "Which of the following is the largest planet in our solar system? A) Earth, B) Mars, C) Jupiter, D) Venus."
  • Answer: "C) Jupiter."

**6. Definition and Explanation

LLMs can provide definitions and explanations for terms, concepts, or phenomena, making them useful for educational purposes.

Example:

  • Question: "What is photosynthesis?"
  • Answer: "Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. It involves converting carbon dioxide and water into glucose and oxygen."

**7. Numeric and Calculation-Based Question Answering

LLMs can perform basic arithmetic calculations and provide answers to numeric questions.

Example:

  • Question: "What is the sum of 15 and 27?"
  • Answer: "The sum is 42."

**8. Temporal Question Answering

LLMs can answer questions related to dates, durations, or time-based events.

Example:

  • Question: "When did the Titanic sink?"
  • Answer: "The Titanic sank on April 15, 1912."

**9. Opinion-Based Question Answering

While LLMs do not have personal opinions, they can provide information on general opinions or viewpoints expressed in society or in specific texts.

Example:

  • Question: "What are some common opinions about the movie 'Inception'?"
  • Answer: "Common opinions about 'Inception' include praise for its complex narrative structure, impressive special effects, and strong performances, particularly by Leonardo DiCaprio."

**10. Complex and Multi-Part Question Answering

LLMs can handle complex questions that require synthesizing information from multiple parts of a text or combining different pieces of knowledge.

Example:

  • Question: "How does a solar eclipse occur, and what are its different types?"
  • Answer: "A solar eclipse occurs when the moon passes between the Earth and the sun, blocking all or part of the sun's light. There are three types of solar eclipses: total, partial, and annular. A total eclipse happens when the moon completely covers the sun, a partial eclipse occurs when only part of the sun is obscured, and an annular eclipse happens when the moon is too far from the Earth to completely cover the sun, leaving a ring of sunlight visible."

**11. Clarification and Follow-Up Question Answering

LLMs can handle follow-up questions that seek clarification or additional information on a previous answer.

Example:

  • Initial Question: "What is the tallest mountain in the world?"
  • Answer: "Mount Everest."
  • Follow-Up Question: "How tall is Mount Everest?"
  • Answer: "Mount Everest is approximately 8,848 meters (29,029 feet) tall."

**12. Comparison Question Answering

LLMs can compare two or more items, concepts, or entities based on provided criteria.

Example:

  • Question: "What are the main differences between Linux and Windows operating systems?"
  • Answer: "Linux is an open-source operating system known for its security and customization, often used in servers and development environments. Windows, developed by Microsoft, is a commercial operating system with a user-friendly interface, widely used in personal and business computers. Linux supports a wide range of distributions, while Windows has a more uniform ecosystem."

These examples illustrate the versatility and range of question-answering tasks that LLMs can handle, making them valuable tools for information retrieval, education, customer support, and many other applications.
