# mcq\_sample\_1

This sample demonstrates how QuML is used to model a simple multiple choice question (with multiple answers), configure the interactions & process the responses to produce results.

![sample mcq image](/files/-MkH_RZ36agfFJyvph8J)

This question is a multiple choice question where the correct answer has two values - “Hydrogen” and “Oxygen”. Below is the logic for evaluating and processing the question:

* If student selects both the correct answers, the score should be 1.0
* If student selects only one of the correct answers, the score should be 0.5
* If student selects any of the wrong answers, a value of 0.5 should be removed from the total score
* If total score if 1.0, show the message “Well done!!!” 
* If total score is between 0 and 1.0 (not including 0 and 1.0, i.e. 0 < score < 1.0), show the message “Better luck next time!!!”
* If total score is less than or equal to 0, show the message “You need to work harder!!!”

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://quml.sunbird.org/v1/samples/mcq_sample_1.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
