Approaching False Answers Creation with LLMs

In this lesson, we will explore the art of crafting effective multiple-choice questions with plausible false options. This skill is crucial for educators who want to create engaging and challenging quizzes. While LLMs are powerful tools, they often struggle with generating non-obvious false answers. By the end of this lesson, you will understand how to guide LLMs to produce better distractors, enhancing the quality of your quizzes.

When using LLMs to generate false options, a common issue is that these options can be too obvious or unrelated to the question. This can undermine the effectiveness of a quiz, as it makes the correct answer too easy to identify. It's important to recognize these pitfalls to avoid them and create more challenging and educational questions.

In this lesson, we will explore a set of useful tricks to make the LLM's false options better.

Precise wording in prompts is key to guiding LLMs in generating plausible false options. Let's explore how specificity can make a difference.

Imagine you are creating a history quiz about famous inventors. A vague prompt might lead to unrelated or obvious false options. Instead, you can use a more specific prompt:

Context:

I am making a history quiz about famous inventors. I need multiple-choice questions where the incorrect options are not too obvious.

Ask:

Create 5 multiple-choice questions about famous inventors. For each question, provide one correct answer and three incorrect options that are plausible but not too easy to eliminate.

Constraints:
- Avoid using options that are obviously unrelated to the question.
- Make sure all options are similar in style and plausibility.

By specifying constraints, you guide the LLM to focus on generating options that are similar in style and plausibility, making the quiz more challenging.

Generally, you can approach explaining constraints to an LLM in the same manner as explaining it to a human. For example:

To craft plausible false options, consider the following strategies:

- **Similarity in Style**: Ensure that all options, including the false ones, are similar in style. This means using similar language, structure, and complexity.
- **Contextual Relevance**: Use context to generate believable distractors. For example, if the question is about inventors, the false options should also be related to inventors or inventions.
- **Plausibility**: The false options should be plausible enough to make the quiz-taker think twice before eliminating them.

You can include precisely this explanation in the prompt and achieve a better answer from an LLM.

One efficient approach is to include an example with an explanation. This will help LLM build it's own "reasoning" properly to generate the questions.

For instance, you can include this in the prompt.

Example Question:

Who invented the telephone?
A) Alexander Graham Bell
B) Thomas Edison
C) Elisha Gray
D) Nikola Tesla

In this example, the false options (B, C, and D) are all plausible because they are well-known inventors, making them more challenging to eliminate. This approach enhances the quality of the quiz by requiring deeper knowledge and consideration.

You can also ask LLM to explain each generated question similarly.

Finally, you can always help the LLM yourself! LLM is a powerful tool, but they require human input, guidance and adjustments to achieve the result. Here is what you can do to approach the false options problem, if LLM fails to generate it:

• LLM can help you a lot with generating quiz questions, but there is no reason to delegate this job completely. You can always come up with some false options yourself
• Ask LLM to provide you with more options that you really need. For example, ask LLM to generate 12 false options for each question. You will be able to choose once that you like the most.

In this lesson, we explored the importance of precise wording in prompts and techniques for crafting plausible false options. By understanding these concepts, you can guide LLMs to generate more effective multiple-choice questions. As you move on to the practice exercises, remember to apply these strategies to create engaging and educational quizzes. This will not only improve your skills but also enhance the learning experience for your students.
