Final answer:
The class representing a single question in a question answer subquery depends on the programming language or framework being used. In a database system, the question may be represented as a row in a table, with each column representing the different attributes of the question. In an object-oriented programming language, the question may be represented as an instance of a Question class, which has properties and methods.
Step-by-step explanation:
The class representing a single question in a question answer subquery depends on the programming language or framework being used. In a database system, the question may be represented as a row in a table, with each column representing the different attributes of the question, such as the question itself, the correct answer, and the difficulty level. In an object-oriented programming language, the question may be represented as an instance of a Question class, which has properties and methods to handle the question and its answers.
For example, let's consider a Java program that handles a question answer subquery:
- Create a Question class with properties like question, correctAnswer, and difficultyLevel.
- Create an array or a collection of Question objects to store multiple questions.
- Use methods to add, remove, or retrieve questions from the collection.
This way, each question in the subquery can be represented by an instance of the Question class.
